Tightbond II or Tightbond III glue is good for a project like this. Both of them are waterproof glues and can take being below the waterline. I would have went with 1x2 or 2x2's for the chines but free 2x4's are the right price. I would have glassed the seams then primed and painted with an outdoor deck/garage paint. I know people who have built simular type boats and didn't use any glass but did cover the entire hull with a couple of coats of tighbond painted it like fiberglass or epoxy resin
@NickD240 if you do all that, that boat will serve you for a very long time. i mean as long as you paint it it every now and then as upkeep im thinking 20 years...
@NickD240 gorrila glue will hold for a long time, i dont know about forever. its a polyurethane glue so its pretty good. as for fiberglass i mean like buy the stuff that you mix and paint you boat with that then lay fiberglass mat then paint with fiberglass resin again. thats fiber glassing.
@NickD240 it does leak now. however i did not use the right materials. if you use gorilla glue it will seal up sooo much better and its only 10 bucks more. just my two cents. an even better way would be to use fiber glass but that would cost more... so its your choice.
@222delta1 for that application, i would recommend fiber glassing the entire boat. this will preserve any type of wood. otherwise a ton of enamel like rustoleum or more expensive boat paint.
@TuscanchickanSlayer well it leaks currently... soo it doesn't work but if i had it to do over again i would fiber glass the bottom and some of the sides... wherever the the joints are.
@bignick703 wish i could man, the whole thing was designed on the fly...i can tell you the lip was curved up so that the board that is on the end is only the 8 inches tall. besides that its like big rectangle box.
Thanks for the info I planned on sealing the plywood to the frame with gorilla glue and silicone the inside. Have you had alot of weight in it? Like I said before great looking boat. My plan is based off of yours except a little bit shorter. (11 feet)
@yardboss1987 thanks for the props! i had two guys in it. me (200 pounds) and my friend (150 pounds) it drew 6 inches of water. with just me in the back it draws about 5 in the back and about 2 in the front. the boat i made weighed about 300 pounds. if your is lighter you might have a higher capacity.
@yardboss1987 well the boat leeks a little bit. about 1/2 inch an hour. in some places. not a huge deal for me. i ended up resealing with gorilla glue and that stopped most of it. i originally used silicone. and one coat of bondo resin. if i had it to over again i would of gorilla glued all seems and put 3 coats of resin on it.
the plywood is just standard interior plywood. this boat only cost me 70 bucks so i wasn't to sad that it leaked a little bit
I would suggest putting transom at an 11 degree angle for engine to sit at proper angle.

U could use that shrink plastic they use on wooden RC planes, would make that water
tight like you couldnt imagine.
its like laminating your wood.
"counter top laminate would do too"

If you fiberglass the seams it will stop the water from leaking completely.
