Bladerider Sailing 1 - with Amac & Rohan

[warlockplaya]

i want one

[1994Guus]

that's f=cking insane man

[MIC960]

Does anybody know what is the sail area to leingt ratio?

[wildblue2]

double the wind speed or greater, nice efficiency.

[Jackle61]

I want to see how you tack, and how well it points to the wind.

[SkipperCharles]

they can sail closer to the wind than a normal dinghy as the apparent wind allows them to!!

they can also stay foiling through-out the tack!!

[Jackle61]

SkipperCharles; Cool, good to know, thanks.

[AdamK153]

hat to burst ur bubble, but the apparent means they cant sail into the wind. They have awful pointing. Thats why they are healed to winward upwind, so the foils pull them to windward.

[dcalimited]

Ok, now THAT is small boat sailing! NICE! What was top speed that day? 20?

[checkstay]

TOOL>all

[aj3071]

are they harder than hobies to sail

[iniciation]

They shure are! Oo

Nice boat

Nice wind

Nice vid!!

5/5

[jhultquist000]

waaaaaaaaaaaaaaay harder. they cant balance without speed.

[BradG902]

hehe that's great! I want one ;)

[Adrenaline552]

how fast was the wind

[BradG902]

6-12 knts

[yotusi8aol]

HAHAHA OMG THIS IS EDGARTOWN! MArthas Vineyard! I sailed here this summer at the edgartown junior regatta HA!

[riccardomascaretti]

che figata!!!!!!

[mouskitto]

This is need for speed!!!!

[nomercymedia]

I love TRIMARANS and Wakeboarding, This is great.

You schould see:

WindSwept extreme wakeboard a no mercy media production

on youtube, The greatest Trimaran video in HIGH QUALITY!

[welderman27]

that thing is awsome

[raww302]

any one here know how much a moth like that would

[Putonyourfknshoes]

a competitive moth thesedays costs upwards of 30g aus

[bouncingyellowskull]

do kasail make sails for mid range yachts

[pablixto26]

VERY FASTER & FUN....WWOOAUUU

[kondziabc]

is not very faster is very fastest

[gurubomb]

what are the physics behind a boat sailing faster than the wind?

[mgalyean]

When you squeeze a watermelon seed between your thumb and your finger the seed moves much quicker than the tips of either your thumb or your finger. Simplistic and not very truly accurate at all, but the principle is similar.

[mgalyean]

Also consider places like Chigago where the wind enters the urban area at some velocity, then because of the height and orientation of the downtown buildings the wind can end up moving much faster down urban canyons than when it entered. So if the wind interacting with objects can accelerate the wind to faster than the average, why couldn't the wind accelerate objects harnessing the wind to speeds greater than the average wind speed?

[lotsoffun]

so would the watermelon be like the water, and the thumb be like the wind, and the seed would be the boat? and it would squeeze the boat forward? Oh ok i get it, that's very cool

[mgalyean]

I was picturing the finger being the water and the seed without from the melon, but sure, that works too. The seed, or boat, is squeezed relatively between two force vectors and moved in the forward direction. The keel and rudder are just an underwater wings pointing down, while the sail is a wing pointing up. Wind and forward motion, along with gravity, create the "squeeze".

Are you ready to move on to how a the bird known as the albatross can fly upwind without flapping its wings? Ha ha.

[lotsoffun]

well i was thinking that the fact that the boat does not move laterally in the water due to the keel and the rudder causes the squeeze as the wind pushes against the sail.

how can an albatross do that? hot thermal currents?

[mgalyean]

Oh yeah, an added force in the Moth case is it has horizontal wings, or foils, underwater, so the forward motion causes the hull to lift out of the water in the same way an airplane lifts higher. So the "squeeze" energy isn't just enough to go faster than the wind, but also to lift up the weight of the boat and crew. Check out the Hydroptere vids on youtube for more hydrofoil action.

[lotsoffun]

i understand the hydrofoil thing, i just didn't get how you can sail faster than the wind, but now i do

[yewwtooob]

1.Put your right arm at a 45 deg. towards the monitor's left side.

2. with the arm straight but elbow bent slide the left fist from the inside of the elbow towards the desk and see the *angular*

movement of your right arm.

3. Now change the angle (flatter) towards yourself. 4. Now you see that you right arm went farther than your left fist.

5. The angle "makes" this happen, as they are relative to each others movement.

[yewwtooob]

6: The angle changes the RELATIVE movement of one to the other. He/She is what they call "reaching" or traveling with the wind sideways(perpendicular). This is why they lean over on the upwind side so they do not flip over. This will get the most speed for the wind speed available. ALL DUE TO THE ANGLE!

7: Salt water burns eyes!! Have fun!!!

[lotsoffun]

though interesting and i understand what you are saying. This doesn't quite answer my question, but I think i figured it out. Thanks.

[Ogsonofgroo]

Moth.

Great vid, five up!

[harrangatang]

That looks amazingly fun, but I'll bet it's a bitch to tack (seems like there's very little space between the sail and that platform)...

[lotsoffun]

yeah, i don't get how any of that would work

[splinadero]

Tool & sailing. the 2 best things in life :)

[jridesnow]

I just talked to a guy and he says that they are very responsive at 10kmh the come out of the water. At that moment they double in speed. Freakin amazing.

[Huckaby]

Nice rig! Wanna race my Rave? See my foiler video.. if you're ever on the east coast - would love to trade boats sometime.

[gbrsailmartin]

i love these boats its so cool when ur in 1 and ur flyin past a tour boat awesome

[heatseeker8434]

Boats like the foiling moth move faster than the wind because they 'create their own' apparent wind as they move forwards, effectively granting them 'extra' wind, which they use to travel faster than the true wind speed. They are not limited by their water line length because, unlike your keelboat, they do not displace the water, but rather plane (or foil) over it.

Hope this helps!

[dotyrs]

As a liveaboard on a full-keel displacement sailboat (38' Hans Christian), I've never understood how a multihull (or, in this case, a Bladerider) can move FASTER than the wind. My boat sure as heck won't! Can anybody explain the concept behind this? Thanks!

[elliottmolnar]

well dotyrs im not sure if im right but it has some thing to do with not having so much resistance on the hull while us monohauls have the whole boat to cary in the water : for examole put your hand out side your car and see wat has more resistance :putting your hand vertical or horizontal.

[svcelticdancer]

Hi Guys another note. It all has to do with true wind and apparent wind. Then after that its the resistance of the hull and spars. So thats where the blade runner wins. I am also living on a monohull and love it

[asyyfjd]

I wonder if its faster than 49er?

[josepanterra]

This is so awesome it's off the scale of extraordinarity! I don't even wonder what it feels like to be flying this contraption doing like 45 kmh. But i've got to say You must have been clinically insane to come up with the idea.

[DobbyM]

it must be hard to control it? or not... but very cool anyway

[highol29]

fuel? you see that thing attached to the mast? its called a sail! is it harder to control seeing the hull is out of the water?

[cruisernet]

this is awesome i feel tempted to get me one of this. good choice of song to go along with this video

[philtrotman]

what you on about fuel?

this doesnt use any fuel its just hydrofoil technology idiots!

[Kaptainrdean]

Unless it's electric of course. does anyone know?

[Kaptainrdean]

wow. I bet eats loads of fuel though

[poypoy2001]

poor Finn....

[jcsrealty]

How much does this boat cost? I want one!!!!

[gbr672]

about £10k

[henrycourse]

This was probs shot at sea in 10kt wind. Remember that these boats only need 5kts to fly

[Bessypas]

wow! I like too :)

[olegmills]

lotsa windward heel. looks weird ;)

[aido179]

im betting that was a lake test? no way you could get that flat calm at sea. it does look quite steady but im guessing it has a lot o weather helm? and how is the rigging set up?

[Heimdall01]

Of course you can have those condition at sea. Like in a protected bay or a fjord.

[andylamy]

Video was shot in Australia, Port Phillips Bay. Not many lakes down-under...

[aido179]

my point exactly

[slrman]

Really great. I have thought about building a hydrofoil catamaran OD 30-40 feet, but am not sure how they would do in a seaway.

[sagnefusciule]

moth :1.................dinghy :0

[123gvina123]

no chance this was taken in 10 knots of wind... this coat is so cool

[xckelly]

great toon, TOOL rock

[yachtie2k4]

rohan rulez

[cesarpeixinho]

pra quem não tem noção da diferença de desempenho desse barco em relação a outros ,preste atenção aos ultimos segundos do video onde o Moth se aproxima de um veleiro de desenho tradicional com muito mais area velica que ele e mesmo assim parece estar em camera lenta...
