hi, i'm planning on making one of these and i was wondering what is the best way to mount the sail poles? and i only weigh 130 pounds so how long/wide would the PVC pipe need to be? thnxs
@TheParkour907 - Good questions, and I wish you success with your cat. You will find information about size and length of pipe at my web site RebelCat.com, under Flotation Chart. It is not possible for me to explain here how to mount the mast or to build your cat - for that I created a DVD which shows and tell everything.
@wjionieis - I believe it. I don';t know what your cat looks like. Mine uses 8: 4 for the deck, 2 for the front and back spreaders. If you're making a cat like the small one here, you may not need any. I used 4 ropes to attach the deck, as you see in the video. Spreaders were tied through holes in the pontoons - a bad idea, because water got in. Ties would be better, so that still makes 8 places to attach the pontoons to what's on them.
@wjionieis - You can also use large pipe clamps made from stainless steel, 1/2" wide, with a screw to tighten it around the cone slipped over the pipe. Keep the screw out of the water to avoid drag. I found these clamps in a store selling wood stoves - I think they are used on the chimney. You can also use screws with flat heads every 3 inches or so. Leather-punch the cone and drill a pilot hole in the pipe, then put in the screw. To reduce drag, calk the trailing edge of the cone.
@wjionieis - Excellent. Be aware that Sch 40 is heavy, so pick cones as long as you can find, like 30", to add flotation front and back. On RebelCat 1 above, I just taped them on with clear packing tape - you will probably want something more durable. No space here to describe the method I used on RebelCat 5 - it's on my DVD.
Yea sure I tested it this summer to view all you have to do is to go on google sketch up and search PVC boat and will be the boat wiith a sail as for the pic I send it to you
@wjionieis - Sure, I'd like to see it. If it's a real boat, upload a pic of it to a free photo-sharing web site, like Flickr, Shutterfly, Picasa, Photobucket, or another of your choice and then post a message here telling where to see it. Even if it's only a 3-D drawing, others might like to see it. If it's a tested design (a real boat that works well), please take a pic of it sailing, so I can consider it for my web site.
@wjionieis - No. The elasticity would allow the deck to slide fore and aft on the pontoons. Ratchet tie downs are recommended. Regarding the drawings of RebelCat 6, they are available to those who buy the DVD.
@wjionieis - Good question. I designed a smaller version of RebelCat 5, but I have not built it. I am working on several other projects, like a house for me to live in, that are at the top of my priority list. Perhaps when I have a home, I will turn that design into a new cat model. For now, anyone who can build RebelCat 5 by following the DVD can probably also scale that model smaller (or larger). I will supply my drawings to help.
@wjionieis - Possibly, for a large order. I don't have their number right now, but it's online. Regarding your other comments on 8" pipe: Pipe this small is best for kids. Adults will be better served with 10" or 12" pipe. Notice that in this video, I am sitting in the middle of the deck, because if I sit on one side, over a pontoon, it goes under water! This cat has very little reserve flotation for an adult (140 lbs). I once carried a friend to the island on this cat - both pipes under water!
@wjionieis - Make sure you ask for PIP (Plastic Irrigation Pipe), not schedule 40 or other thick-walled pipe. You want the thinnest PIP - there are at least three grades,like 64, 80 and 100 - I think it's a rating for psi. You want the thinnest of those, it's also the cheapest. Some sellers price their pipe outrageously high. I paid about $80 for 40' of 10" pipe at Sierra Irrigation in Albuquerque - that's $2 per foot. The price is also affected by the price of oil.
@wjionieis - Yes, I do. First, this kind of PVC pipe is used mostly for irrigation in agriculture and golf courses, so if you have those around you, the pipe is probably also there. PIP means Plastic Irrigation Pipe, but it is not well known, even by PVC pipe distributors, in areas without large-scale irrigation. So do a search for irrigation pipe in your area. Good luck.
@wjionieis - As this cat was an experiment, I used packing tape. Later, I developed a much better method for joining the cones to the pipes which blends the edge of the cone with the pontoon, reducing drag. If you watch the video of RebelCat 5 sailing here on my channel, you will notice that the cones aft leave almost no wake, so the system works well. It's on my DVD but much to long to describe here.
@wjionieis - I don't know of a place that ships for free. PVC pipe comes in standard lengths of 20 and 40 feet, so it takes a truck to ship, and a long truck for the 40' stuff. If you find a free shipper, let me know. I'll post it on my web site. I suppose if you buy a lot of pipe from an irrigation supplier (best place to find it), they might ship for free. But small amounts? Unlikely. But you can ask. All they can say is no or yes.
@cosmicway - Yes, that works, but you will find the bows drag a lot in the water, right? Traffic cones are actually quite easy to attach and give a smooth ride. On RebelCat 5, I used them aft as well, and you can see the video on my channel here, showing how well cones reduce wake, even sailing quite fast. Small wake means more efficient design and more energy going to make the cat move forward.
@wjionieis - Yes,it would work, but not very well, because those reducers are not cones, they have a big step down in diameter which will drag in the water. Better are traffic cones, longer the better. My DVD shows how to attach them to the PVC pipe pontoons, front and rear if desired. At the rear, they leave absolutely no wake - really great for cats. A megaphone (cone) might work, but I haven't tried that. Good luck.
Great video as im defiantly going to make this my summer project even though im 14 but hey if its as easy as you say ill be on the water in no time thanks!
@htkendall - That's the spirit! See you on the water... Oh, be sure to check out my other video of "RebelCat 5 on the MOVE!" here on YouTube. You'll see what fun this cat can be on a breezy day. It MOVES!
@leno140 - Well, sure I survived, and thrived! If you mean was I stranded, no, I could leave anytime. But I wanted to get to that island, and a raft was what I made, then later transformed it into a sailboat. But yes, I did survive and live to tell about it. My DVD explains a bit of that, and my latest catamaran, RebelCat 5 is the subject of that DVD - how you can make one yourself. For a video of it, see my channel for the one ON THE MOVE!
I live in oregon and would love to make one using your plan so my question is, how would the rebel cat 6 do in deep deep water and a large river that sometimes gets pretty big wake and if not would u recommend the rebel cat 5?
@CSATexan - Well, I agree, and I have often wondered why he didn't put a sailboat together long before, making sails from woven palm fronds. But then, there would be no movie of him stick there.
@marjamada - I would not recommend a take-apart cat for large chop and waves. The structure will handle maybe three feet of chop, but that kind of stress on joints is not recommended on a daily basis. Both cat designs use a flexible joint which gives with tension, preventing breakage, but you're looking at a lot of flexing in big waves and chop - not what I would advise.
I've always been at peace on the water and I can see that you share the same feeling. I kayak and I've made some modifications and add ons. You can see my uploads on my channel joeebear. Thanks
@jackrakino - A step-by-step instructional DVD is available at my web site for $39.75, satisfaction guaranteed. This DVD covers the construction of RebelCat 5, which is the latest incarnation of the RebelCat series which this little sailboat - RebelCat 1 - began in Brazil. Using this DVD, you can make whatever size catamaran you need, from a small one-person cat to a large party boat, like RebelCat 4 (see RebelCat.com). See the sailing video on this channel 'RebelCat 5 on the move'.
so the rebel cat 6. its basically this, with just a few changes, and smaller than the rebel cat 5? i just want to clarify this. im 14, and probably going to buy plans
@crazytacostudios - Exactly right - RebelCat 6 is designed like RC 5, just smaller. The plans on DVD are clear enough that anyone can build a cat with 8" or 10" or 12" or even 15" pipe and have a usable cat. Just scale up or down from the plans. If you look at the video of RC 5 sailing (...on the MOVE! it's called) on this channel, you will get a better idea of how it performs.
@001grady - The parts are easy to move around and put together. Check PVC prices in your area - they differ widely. For a cat like this one, the rest of the parts are scrap wood, bamboo mast and boom, plastic tarp sail - stuff you might have already. The pipes are the only real cost. If you want to upgrade to a real sailboat, check out the video on my channel about RebelCat 5 on the MOVE! - it shows the latest version of this prototype which can be made smaller, even the size as this one.
Hey i have some questions. SO im looking to build one of these. i go to maine all summer to a bay called casco bay. Theres over 150 islands that are just asking to be explored. What size pvc pipes did you use. Also did you have to glue the end caps on or did they just fit on water tight. ?? please respond
@reidrr2 - This prototype was made from 20cm/8" diameter pipe, caps glued on, but later models use larger pipe and heat-shaped bows for better wave-piercing. Pipes here are about 10', but that's the shortest I would use, and 10" diameter is minimum for an adult to be safe. Notice I'm sitting in the middle of the deck - that's because the pontoons won't support me on one side. Great for kids, adults would probably be better served with 10" or 12" pipes.
@xXbloodbabaXx - Well, when you consider the diesel ferry and motor boats, fish, runoff from cattle fields, etc., I suppose my swimming there made little difference. So far, nobody complained about their water ;-)
@podboq2 - Good idea - I tried that with some gear in one hand, didn't make it, it's a long way. Besides, having a raft let me explore the whole reservoir, in style. Hard to do that swimming. And, the raft led me to the discovery of the catamaran design, so it was a productive experiment.
pbr2424 - If you check my web site, you will see that the DVD IS free... If you buy it and build the catamaran, then send me pics of it and 5 minutes of video of it sailing, to be posted on my web site, I will refund your money, if you are one of the first 20 people to do it. I keep my promise.
Sir, Im very impressed with your Catamaran Sail and this video. I've always wanted one of these but it costs a fortune to buy one (at least where im from).
I would like to build one, NO, im going to build one. Just a simple one like this.
But i dont know anything about installing the mast and the measurements and putting it together. How i wish i could buy your DVD, but i cannot afford it.
I would appreciate it if maybe you can give me a few tips.
As the sails were only needed for a month, I made them from sheet plastic from a hardware store. If you want better sails, you can use Tyvek or poly tarp, both relatively inexpensive.
Good question. As this was a quick experimental craft, I just taped them on with clear packing tape, then taped the tip closed - not at all what I would do for a permanent construction. See my other RebelCat videos for that.
As this was a 'temporary' cat which I would leave there, I just taped them on with clear packing tape and taped the tip closed. My DVD shows how to mount them on the pipes permanently.
you inspired me friend..I have made a few boats in my day. wanting to build a sun fish I came on here and saw your boat..inspiration!!!..I had to use 4 inch diameter drainage pipe for cost and availability reasons. I used 3 pieces of 4 inch diameter pvc by 15 foot. Made a triangle out of them, used end caps and 3 two liter coke bottles instead of traffic cones. cost per pontoon ...25$ each, and if one becomes punctured the other 2 will keep me afloat..your idea inspired me..thank you!!!
You inspired me friend..I have built a sea kayak and a canoe so far. I was looking on youtube because I wanted to make a sun fish and saw your vid. I am presently making a cat like yours with a few variations. Mainly I couldnt find affordable drainage pipe of the size diameter that would float 2 people.For cheep I could get 4 inch pvc. So I made my pontoon with 3 pieces of 4 inch pvc by 15 foot long. end caps and all each pontoon cost 25$ each.
im making one similar to urs. its gonna b lil bigger with some more deck space and a slight hightened deck in the back. my grandpa and i have sailed all out lives so he should b able 2 help =)
very nice story telling, just before bed for work in four hours, i could imagine me building a boat like this when i visit the philippines. Can you tell me, would a twin small electric motor in each hull be a good place? I want to make a simple solar boat with no sail for now. Thanks for the videos.
I'm about to make a cat myself. It's supposed to get a human propulsion system like pedals on a bike. Optionally a sail too. I was wondering how you came to using those PVC pipes in particular, and how you figured out they would be able to carry you on water and not sink like a brick. You even added a sail as well.
Currently, I'm working on the maths and figures of my overall design so I was curious about your method.
Very inspirational vid. This is similar to what happened to me and canoes.
I'm not using a pipe, I'm using a custom shape involving mathematical functions for easy integration. It's not a homogeneous body either as it has a skeleton. The function for the cross section is y=minimum_of(sqrt(a*x),sqrt(a-a*x)).
Lengthwise is a more complex function though.
I did check out your website and pipes are indeed easy; I just don't roll that way. My love for math is too big for easy solutions :-D
ok first of all, video, is inspirational. just wanted to say that, secondly Im intrested in the rudder and keel design you have on this. Seems simple, but I can't find anywhere on your website where you go in depth about it, I am planning to make a cat, out of 2 kayaks I have sitting in my back yard.
Thank you zekeWN. Check my site under RC5 Updates - I just uploaded new rudder and centerboard designs for RebelCat 5. They are covered in detail on my DVD. For this prototype cat, both were primitive and functional, but you can do much better for your project.
Wow, thank you. If you have not seen my latest video of my latest catamaran, check out the one that starts with 'PVC Pipe Catamaran'. Real video this time, finally.
I keep going back to this video and watching it. I guess I'm gearing up to building something like this. I'm a man much like yourself just younger. Your video inspires me and really speaks to me.
PVC pipe prices vary widely, so shop around. You want PIP (thinwall) pipe, NOT schedule 40 (thick). I got 40' of 10" diameter pipe for just over $80 last year. 8" pipe is cheaper, but I now think that 10" is the minimum for an adult's boat. 8" is okay for kids. Depends on how and where you plan to sail. If you stay close to shore, an adult can have fun on a cat made from 8" pipe, but flotation is barely adequate. For serious sailing, use 10" or 12". See my website FAQ for more info.
Before you make your boat, check the Flotation Chart on my website and calculate how much flotation you will have with your pipes. It should be TWICE your total weight (you and your boat). If you already have the pipe, good luck. If you don't have the pipe, I suggest getting pipe not smaller than 8" in diameter. Remember, 8" pipe has 4 times as much flotation as 4". As the diameter doubles, flotation quadruples. Too much flotation is always better than too little. Read the FAQs at my site.
I weigh 140 lbs. RebelCat 1 floated me with no reserve flotation. Put traffic cones front and back, fill them with foam, and you will be fine, if you are not heavier than I. Sure, go for it.
monohull sailor here:) catamarans have always intrigued me. What you have done is very unique, thanks for sharing! I would have never thought creating one would be so simple and cheep, you even included a jib sail! I subscribed
I'm pleased that you found this interesting. See the latest one if you haven't. And if you decide to make one, my DVD - which I just completed - will be available this month. It shows how to make the one in that recent video. Trailer coming soon.
Yes, the rudder is turned with a 'tiller' or handle, and it rotates on an axle or hinge. Tiller left, boat turns right. If you mean sewing the front edge of the sail to create a tube or pocket to slip over the mast, yes, that's one way to do it. In strong wind you can't lower the sail, but you can wrap it around the mast or roll it up. The cats I built since this little prototype have sails that can be raised and lowered and 'reefed' (made smaller). My DVD on RebelCat 5 shows how to do this.
Thank you, I'm glad my video inspired you. I'll be brief, because I get a 'ton' of emails asking how to make a cat. Yes, cut off the cone base. Attach with tape or rivets or glue. Megaphones might work instead. I can't draw a rudder here. Look on the web for possible shapes. Or, get my DVD coming out this month - it shows you everything, step-by-step. Good luck!
Yes, plans are in the works for RebelCat 5, the latest model and I believe the best of all, because I used the best ideas from the previous cats to make it. It is FAST, it is comfortable, it has lots of storage for long cruises, it carries either 2 or 4 people, depending on which version you make, and it is fairly inexpensive to build from materials you can find - no boat-building experience necessary. Coming soon, really.
I used one 20cm or 8" pipe of 6m or about 20 feet, cut off the 'bell' end (larger, for mating with another pipe), then cut the remaining pipe in two equal pieces of about 10' each, capped the ends, added traffic cones to the front (but the back needs them too, or it makes lots of noise and slows you down)..
ricnoah1993, thank you for hanging in there for so long. You really are a patient sailor. The good news is that I have just moved back into my old place and set up my office, after working for 4 months building a house on my land in a remote corner of AZ. I am here to do just what you asked - to complete the DVD of plans for RebelCat 5 and get them out there. Thanks again brother, and stay tuned for the unveiling of the long-overdue DVD.
I am going to complete this DVD within two months or I will eat my hat (low-calorie, all cotton). My house will be another DVD: Rainwater collection and storage, gravity fed to house, solar heating, solar hot water, underground air cooling system, graywater, composting toilet, solar electric and wind. Look for it here, one day.
Well, fast is a relative description. I'd say about as fast as I can run, but given a stronger wind, there is no way I could run that fast. See comment above. My latest cat is FAST.
That little prototype was fast, but my recent cats based on it are much faster, even though they are larger and heavier. RebelCat 5, my latest, is the fastest yet, due to shaped bows, long pontoons and lots of sail area. DVD of plans coming soon, finally.
hey great video but do you remember how far do the pipes sink down into the water, because im going on a trip and most of the water is only 1and a half foot deep amd i dont wantto be stuck on the rocks
Good question. Calculate your weights carefully and accurately. You should have twice the flotation as total weight, so you never go more than half the pipe/pontoon in the water. If you use 10" pipe, you should have 5" above water at max loading. But your rudder and daggerboard or centerboard will be well below your pontoons, so make them easy to pull up in the shallows.
Not really, but some have made small cats from inflatable pontoons. However, a blowout far out in the water would not be fun. I suppose you could make a mold and use fiberglass, but it will be heavy.
I really want tobuild this, but at my home depot, they only have up to 6" pvc pipe, I went to a plumbing supply store and it was extremly expensive, plz help
As gasoline prices went up, so did PVC. I got great deals in Albuquerque at Sierra Irrigation, like half the cost of AZ. Remember, you want PIP (thinwall) pipe, not schedule 40. It's the thinnest and cheapest.
I live near the water but have never been able to afford a sailing boat being a teenage myself. im currently building one of these since they look so cool but the main problem i seem to have is getting a tall enough mast pole. Since i live in the city, bamboo is quite hard to find--is there any alternative i could use--say joining two 3 m wooden poles together side by side?
I've been using aluminum pipe, up to 2" diameter, but it is now costly. Try salvage yards, old awning rollers from motor homes/trailers. Home Depot sells wooden railing, up to about 16' long. You can also shave down a 4 x 4 of good quality and straight.
ive been wanting to build a pontoon for the longest time and ive always wondered if the pvc would float. it does as youve prooved. thanks for this video as it has inspired me to build one as soon as i can.
That's good news, joshpick18, now you can build your dream. You may want PIP grade PVC pipe, thinwall and lightest of all of them, it's what I use. Don't go less than 8" diameter @ 10 feet long, 10" better for floating adults. I look forward to seeing your craft when you're done.
It IS fun. I've redesigned this little cat and will soon begin building it. The newer version is the same size, but it benefits from me having made three more since this one. I've now used 8", 10" 12" and 15" diameter PVC pipe. The fun factor increases as the size of the boat decreases.
You are awesome too, my friend, and yes, you will really enjoy one of these cats. A redesign and upgrade of the little one in this video is done and about to be built, so stay tuned.
These pontoons are 20cm (8") diameter, made from 6m (20') with the bell removed before cutting in half, so less than 10' each. However, flotation is minimal and best suited for a small adult or teenager. Sails are plastic sheeting. Poly tarps work well also.
Good news: I got 20' of 8" PVC pipe & caps in Albuquerque - must be the best price on Earth: Sierra Irrigation. Four traffic cones ordered. Bought the wood and the mast. This will be RebelCat 6, a remake and upgrade of RC 1 you see in this video, as promised. My guess is it can be built for about $150. Stay tuned.
i saw a kind of boat once, it had one big hull that you would sit it, and one smaller one, the smaller one was boyent so it didnt sink but heavy so the boat didnt capsize, the smaller hull was attached to the bigger one with a cuple of planks i guess, i dont know i didnt really look at it for a long time, what do you call this kind of boat?
I when to a local plumbing supply store, (i want 12" pvc by the way) and they said it was like $20 per yard! equaling $400, and the end caps are like $30 dollers per cap so thats like, $520! I dont see how this can be done for about $100.
Good idea. If you need step-by-step guidance while building your cat, my DVD of RebelCat 5 will be coming out soon. Watch for a video of it here, or subscribe and you will get an email when it's announced here. Good luck.
The yellow sail on this little boat is made from plastic sheeting from a hardware store. The boat was an experiment, and I knew I would leave the boat there when I left Brazil, so I used the cheapest material I could find. If you want a sail to perform well and also survive months or years of sailing, I suggest polyester fabric. Some use blue or white polytarp and make usable sails from it. Tyvek is also okay. Many non-stretch fabrics will work, cotton, light canvas, etc.
Do you know a date? or even a month? because I need to build 1 more, and if i could id like to build rebal cat 5. I also want to take a video of my and my friend sailing, would you let us do that if we linked to you?
The DVD of plans for RebelCat 5 will be ready at the end of Sept. at the earliest. Many people are waiting for them, but I want to be sure that the cat performs well under different conditions, including medium to strong wind, and that has not been possible so far. I'm also making some improvements and need to include them in the plans. Your other questions regarding mast, sail and rudder would require far more space than is possible here. I suggest reading more about how a sailboat works.
can you please just answer one question, how dose the sail attach to the boom? it you dont tell me I'm gonna sew on strips of fabric and put on snapes
There are many ways to attach the sail to the boom. Put grommets in the sail, one in the front lower corner (tack) and one at the rear corner (clew), then tie the sail to eyebolts or other hardware on the boom to stretch it out. Google 'tack' and 'clew' under 'images' and you'll see what they look like on some boats. Two attachments should be enough if your sail has a strong lower hem (foot) and can handle the forces. Reinforce the sail at the grommets to prevent tears. Good luck.
you could put a grove in the mast and boom and have some kind of plastic runer that would fit into the groves on the mast and boom and the one on the boom having an hole were u can conect the out haul to and another for the one on the mast that would conect to the hailyard
Good points. All later Rebel Cats have sail tracks on the mast, outhaul, downhaul, traveler, adjustable jib fairlead position, halyards, sheets, cleats... the works.
hi, i'm planning on making one of these and i was wondering what is the best way to mount the sail poles? and i only weigh 130 pounds so how long/wide would the PVC pipe need to be? thnxs

@TheParkour907 - Good questions, and I wish you success with your cat. You will find information about size and length of pipe at my web site RebelCat.com, under Flotation Chart. It is not possible for me to explain here how to mount the mast or to build your cat - for that I created a DVD which shows and tell everything.

You won't believe it but I just got 4 free cones also how many tie downs do I need 2 or 4?
wjionieis 3 months ago
@wjionieis - I believe it. I don';t know what your cat looks like. Mine uses 8: 4 for the deck, 2 for the front and back spreaders. If you're making a cat like the small one here, you may not need any. I used 4 ropes to attach the deck, as you see in the video. Spreaders were tied through holes in the pontoons - a bad idea, because water got in. Ties would be better, so that still makes 8 places to attach the pontoons to what's on them.
marjamada 3 months ago
Okay sweet also for the cones should I just overlap it and then calk it or something
wjionieis 3 months ago
@wjionieis - You can also use large pipe clamps made from stainless steel, 1/2" wide, with a screw to tighten it around the cone slipped over the pipe. Keep the screw out of the water to avoid drag. I found these clamps in a store selling wood stoves - I think they are used on the chimney. You can also use screws with flat heads every 3 inches or so. Leather-punch the cone and drill a pilot hole in the pipe, then put in the screw. To reduce drag, calk the trailing edge of the cone.

I just got 18 feet of free schulde 40 pipe also how do you put on the cone I did not under stand it in your video
wjionieis 3 months ago
@wjionieis - Excellent. Be aware that Sch 40 is heavy, so pick cones as long as you can find, like 30", to add flotation front and back. On RebelCat 1 above, I just taped them on with clear packing tape - you will probably want something more durable. No space here to describe the method I used on RebelCat 5 - it's on my DVD.

Yea sure I tested it this summer to view all you have to do is to go on google sketch up and search PVC boat and will be the boat wiith a sail as for the pic I send it to you

I made a 3d PVC sailboat based on your boat I was wondering if you wanted to see it and maybe I could put on your web site
wjionieis 4 months ago
@wjionieis - Sure, I'd like to see it. If it's a real boat, upload a pic of it to a free photo-sharing web site, like Flickr, Shutterfly, Picasa, Photobucket, or another of your choice and then post a message here telling where to see it. Even if it's only a 3-D drawing, others might like to see it. If it's a tested design (a real boat that works well), please take a pic of it sailing, so I can consider it for my web site.

this would be considered a bermuda rig, really cool and simple to make.

Would bungy cords work to attach the deck to the pipe
wjionieis 5 months ago
@wjionieis - No. The elasticity would allow the deck to slide fore and aft on the pontoons. Ratchet tie downs are recommended. Regarding the drawings of RebelCat 6, they are available to those who buy the DVD.
marjamada 5 months ago
Okay sweet thanks one other thing is the the 6th boat of your series almost done?
wjionieis 5 months ago
@wjionieis - Good question. I designed a smaller version of RebelCat 5, but I have not built it. I am working on several other projects, like a house for me to live in, that are at the top of my priority list. Perhaps when I have a home, I will turn that design into a new cat model. For now, anyone who can build RebelCat 5 by following the DVD can probably also scale that model smaller (or larger). I will supply my drawings to help.

Wow does Sierra irrigation ship
wjionieis 7 months ago
@wjionieis - Possibly, for a large order. I don't have their number right now, but it's online. Regarding your other comments on 8" pipe: Pipe this small is best for kids. Adults will be better served with 10" or 12" pipe. Notice that in this video, I am sitting in the middle of the deck, because if I sit on one side, over a pontoon, it goes under water! This cat has very little reserve flotation for an adult (140 lbs). I once carried a friend to the island on this cat - both pipes under water!

How did you pay for PVC because I found some but it's 300$ for 20 feet of it
wjionieis 7 months ago
@wjionieis - Make sure you ask for PIP (Plastic Irrigation Pipe), not schedule 40 or other thick-walled pipe. You want the thinnest PIP - there are at least three grades,like 64, 80 and 100 - I think it's a rating for psi. You want the thinnest of those, it's also the cheapest. Some sellers price their pipe outrageously high. I paid about $80 for 40' of 10" pipe at Sierra Irrigation in Albuquerque - that's $2 per foot. The price is also affected by the price of oil.
marjamada 7 months ago
Thank you marjamada I am still having trouble finding the PVC do you have any advice
wjionieis 7 months ago
@wjionieis - Yes, I do. First, this kind of PVC pipe is used mostly for irrigation in agriculture and golf courses, so if you have those around you, the pipe is probably also there. PIP means Plastic Irrigation Pipe, but it is not well known, even by PVC pipe distributors, in areas without large-scale irrigation. So do a search for irrigation pipe in your area. Good luck.

How do you attach the traffic cones
wjionieis 7 months ago
@wjionieis - As this cat was an experiment, I used packing tape. Later, I developed a much better method for joining the cones to the pipes which blends the edge of the cone with the pontoon, reducing drag. If you watch the video of RebelCat 5 sailing here on my channel, you will notice that the cones aft leave almost no wake, so the system works well. It's on my DVD but much to long to describe here.

Marjamada what is the best place to buy PVC that will ship it for free
wjionieis 7 months ago
@wjionieis - I don't know of a place that ships for free. PVC pipe comes in standard lengths of 20 and 40 feet, so it takes a truck to ship, and a long truck for the 40' stuff. If you find a free shipper, let me know. I'll post it on my web site. I suppose if you buy a lot of pipe from an irrigation supplier (best place to find it), they might ship for free. But small amounts? Unlikely. But you can ask. All they can say is no or yes.

what i did for the nose was use 45 degree angles
cosmicway 8 months ago
@cosmicway - Yes, that works, but you will find the bows drag a lot in the water, right? Traffic cones are actually quite easy to attach and give a smooth ride. On RebelCat 5, I used them aft as well, and you can see the video on my channel here, showing how well cones reduce wake, even sailing quite fast. Small wake means more efficient design and more energy going to make the cat move forward.
marjamada 7 months ago
Nice video mr. Adams for mine I thought i would use Reducing couplings for the nose do you think it would work please respond
wjionieis 8 months ago
@wjionieis - Yes,it would work, but not very well, because those reducers are not cones, they have a big step down in diameter which will drag in the water. Better are traffic cones, longer the better. My DVD shows how to attach them to the PVC pipe pontoons, front and rear if desired. At the rear, they leave absolutely no wake - really great for cats. A megaphone (cone) might work, but I haven't tried that. Good luck.

marjamada 9 months ago
@marjamada - I would not recommend a take-apart cat for large chop and waves. The structure will handle maybe three feet of chop, but that kind of stress on joints is not recommended on a daily basis. Both cat designs use a flexible joint which gives with tension, preventing breakage, but you're looking at a lot of flexing in big waves and chop - not what I would advise.

crazytacostudios 1 year ago
@crazytacostudios - Exactly right - RebelCat 6 is designed like RC 5, just smaller. The plans on DVD are clear enough that anyone can build a cat with 8" or 10" or 12" or even 15" pipe and have a usable cat. Just scale up or down from the plans. If you look at the video of RC 5 sailing (...on the MOVE! it's called) on this channel, you will get a better idea of how it performs.

how much would it cost without a sail im eleven so how could i move it
001grady 1 year ago
@001grady - The parts are easy to move around and put together. Check PVC prices in your area - they differ widely. For a cat like this one, the rest of the parts are scrap wood, bamboo mast and boom, plastic tarp sail - stuff you might have already. The pipes are the only real cost. If you want to upgrade to a real sailboat, check out the video on my channel about RebelCat 5 on the MOVE! - it shows the latest version of this prototype which can be made smaller, even the size as this one.
marjamada 1 year ago
Hey i have some questions. SO im looking to build one of these. i go to maine all summer to a bay called casco bay. Theres over 150 islands that are just asking to be explored. What size pvc pipes did you use. Also did you have to glue the end caps on or did they just fit on water tight. ?? please respond
reidrr2 1 year ago
@reidrr2 - This prototype was made from 20cm/8" diameter pipe, caps glued on, but later models use larger pipe and heat-shaped bows for better wave-piercing. Pipes here are about 10', but that's the shortest I would use, and 10" diameter is minimum for an adult to be safe. Notice I'm sitting in the middle of the deck - that's because the pontoons won't support me on one side. Great for kids, adults would probably be better served with 10" or 12" pipes.

Good question. As this was a quick experimental craft, I just taped them on with clear packing tape, then taped the tip closed - not at all what I would do for a permanent construction. See my other RebelCat videos for that.

you inspired me friend..I have made a few boats in my day. wanting to build a sun fish I came on here and saw your boat..inspiration!!!..I had to use 4 inch diameter drainage pipe for cost and availability reasons. I used 3 pieces of 4 inch diameter pvc by 15 foot. Made a triangle out of them, used end caps and 3 two liter coke bottles instead of traffic cones. cost per pontoon ...25$ each, and if one becomes punctured the other 2 will keep me afloat..your idea inspired me..thank you!!!

You inspired me friend..I have built a sea kayak and a canoe so far. I was looking on youtube because I wanted to make a sun fish and saw your vid. I am presently making a cat like yours with a few variations. Mainly I couldnt find affordable drainage pipe of the size diameter that would float 2 people.For cheep I could get 4 inch pvc. So I made my pontoon with 3 pieces of 4 inch pvc by 15 foot long. end caps and all each pontoon cost 25$ each.

I'm about to make a cat myself. It's supposed to get a human propulsion system like pedals on a bike. Optionally a sail too. I was wondering how you came to using those PVC pipes in particular, and how you figured out they would be able to carry you on water and not sink like a brick. You even added a sail as well.
Currently, I'm working on the maths and figures of my overall design so I was curious about your method.
Very inspirational vid. This is similar to what happened to me and canoes.
FHomeBrew 2 years ago
Check my web site for the Flotation Chart, and you will know how much pipe and what diameter will float how much weight. Simple math.
marjamada 2 years ago
I'm not using a pipe, I'm using a custom shape involving mathematical functions for easy integration. It's not a homogeneous body either as it has a skeleton. The function for the cross section is y=minimum_of(sqrt(a*x),sqrt(a-a*x)).
Lengthwise is a more complex function though.
I did check out your website and pipes are indeed easy; I just don't roll that way. My love for math is too big for easy solutions :-D

how much is the pipe? Im in the U.S. if it different can u tell me ?
XxDarkEaglexX26 2 years ago
PVC pipe prices vary widely, so shop around. You want PIP (thinwall) pipe, NOT schedule 40 (thick). I got 40' of 10" diameter pipe for just over $80 last year. 8" pipe is cheaper, but I now think that 10" is the minimum for an adult's boat. 8" is okay for kids. Depends on how and where you plan to sail. If you stay close to shore, an adult can have fun on a cat made from 8" pipe, but flotation is barely adequate. For serious sailing, use 10" or 12". See my website FAQ for more info.
marjamada 2 years ago
ya im 12 and weigh about 100 pounds and im gana try with 4 4.5 pipes and see if that works thanks!
XxDarkEaglexX26 2 years ago
Before you make your boat, check the Flotation Chart on my website and calculate how much flotation you will have with your pipes. It should be TWICE your total weight (you and your boat). If you already have the pipe, good luck. If you don't have the pipe, I suggest getting pipe not smaller than 8" in diameter. Remember, 8" pipe has 4 times as much flotation as 4". As the diameter doubles, flotation quadruples. Too much flotation is always better than too little. Read the FAQs at my site.

marjamada 2 years ago
Yes, the rudder is turned with a 'tiller' or handle, and it rotates on an axle or hinge. Tiller left, boat turns right. If you mean sewing the front edge of the sail to create a tube or pocket to slip over the mast, yes, that's one way to do it. In strong wind you can't lower the sail, but you can wrap it around the mast or roll it up. The cats I built since this little prototype have sails that can be raised and lowered and 'reefed' (made smaller). My DVD on RebelCat 5 shows how to do this.
marjamada 2 years ago
Thank you, I'm glad my video inspired you. I'll be brief, because I get a 'ton' of emails asking how to make a cat. Yes, cut off the cone base. Attach with tape or rivets or glue. Megaphones might work instead. I can't draw a rudder here. Look on the web for possible shapes. Or, get my DVD coming out this month - it shows you everything, step-by-step. Good luck!

whotookthecookies 2 years ago
Yes, plans are in the works for RebelCat 5, the latest model and I believe the best of all, because I used the best ideas from the previous cats to make it. It is FAST, it is comfortable, it has lots of storage for long cruises, it carries either 2 or 4 people, depending on which version you make, and it is fairly inexpensive to build from materials you can find - no boat-building experience necessary. Coming soon, really.

when You said 20ft by 8 in ,does that mean for each pontoon? or cut the 20 ft pipe for 2 10 ft pontoons

I used one 20cm or 8" pipe of 6m or about 20 feet, cut off the 'bell' end (larger, for mating with another pipe), then cut the remaining pipe in two equal pieces of about 10' each, capped the ends, added traffic cones to the front (but the back needs them too, or it makes lots of noise and slows you down)..

leviterande 3 years ago
That little prototype was fast, but my recent cats based on it are much faster, even though they are larger and heavier. RebelCat 5, my latest, is the fastest yet, due to shaped bows, long pontoons and lots of sail area. DVD of plans coming soon, finally.

hey great video but do you remember how far do the pipes sink down into the water, because im going on a trip and most of the water is only 1and a half foot deep amd i dont wantto be stuck on the rocks
T3you 3 years ago
Good question. Calculate your weights carefully and accurately. You should have twice the flotation as total weight, so you never go more than half the pipe/pontoon in the water. If you use 10" pipe, you should have 5" above water at max loading. But your rudder and daggerboard or centerboard will be well below your pontoons, so make them easy to pull up in the shallows.
marjamada 2 years ago
Thats fantastic, thank you for sharing a most unique idea, I have to build one now.

I've been using aluminum pipe, up to 2" diameter, but it is now costly. Try salvage yards, old awning rollers from motor homes/trailers. Home Depot sells wooden railing, up to about 16' long. You can also shave down a 4 x 4 of good quality and straight.

These pontoons are 20cm (8") diameter, made from 6m (20') with the bell removed before cutting in half, so less than 10' each. However, flotation is minimal and best suited for a small adult or teenager. Sails are plastic sheeting. Poly tarps work well also.

i saw a kind of boat once, it had one big hull that you would sit it, and one smaller one, the smaller one was boyent so it didnt sink but heavy so the boat didnt capsize, the smaller hull was attached to the bigger one with a cuple of planks i guess, i dont know i didnt really look at it for a long time, what do you call this kind of boat?

I when to a local plumbing supply store, (i want 12" pvc by the way) and they said it was like $20 per yard! equaling $400, and the end caps are like $30 dollers per cap so thats like, $520! I dont see how this can be done for about $100.

Good idea. If you need step-by-step guidance while building your cat, my DVD of RebelCat 5 will be coming out soon. Watch for a video of it here, or subscribe and you will get an email when it's announced here. Good luck.

The yellow sail on this little boat is made from plastic sheeting from a hardware store. The boat was an experiment, and I knew I would leave the boat there when I left Brazil, so I used the cheapest material I could find. If you want a sail to perform well and also survive months or years of sailing, I suggest polyester fabric. Some use blue or white polytarp and make usable sails from it. Tyvek is also okay. Many non-stretch fabrics will work, cotton, light canvas, etc.

The DVD of plans for RebelCat 5 will be ready at the end of Sept. at the earliest. Many people are waiting for them, but I want to be sure that the cat performs well under different conditions, including medium to strong wind, and that has not been possible so far. I'm also making some improvements and need to include them in the plans. Your other questions regarding mast, sail and rudder would require far more space than is possible here. I suggest reading more about how a sailboat works.

can you please just answer one question, how dose the sail attach to the boom? it you dont tell me I'm gonna sew on strips of fabric and put on snapes
Twofunnyjews 3 years ago
There are many ways to attach the sail to the boom. Put grommets in the sail, one in the front lower corner (tack) and one at the rear corner (clew), then tie the sail to eyebolts or other hardware on the boom to stretch it out. Google 'tack' and 'clew' under 'images' and you'll see what they look like on some boats. Two attachments should be enough if your sail has a strong lower hem (foot) and can handle the forces. Reinforce the sail at the grommets to prevent tears. Good luck.

you could put a grove in the mast and boom and have some kind of plastic runer that would fit into the groves on the mast and boom and the one on the boom having an hole were u can conect the out haul to and another for the one on the mast that would conect to the hailyard

Good points. All later Rebel Cats have sail tracks on the mast, outhaul, downhaul, traveler, adjustable jib fairlead position, halyards, sheets, cleats... the works.
