Default k so need imput

k i just finished a depron boat and it works great except for when it starts to hydroplane it can flip on a had turn. the other thing is it has no reverse so thats not to good. to fix these problems i was thinking about ading 2 pontoons that went backwards of the boat and put to the sides. there is no problaem with the prop hitting since its a puller. how does that sound to all yall?

next thing is im starting to plan my next build. i pretty sure ill use the same motar speed control and battery. i think ill keep the same one eighth depron for the inside supports and then take some 2 32nd inch depron for an outside followed with either fiber glass(would that add a lot of weight) or epoxy some kevalar cloth to it and put a coating of epoxy over the Kevalar. does this sound good? would kevalar work or not?

Are the sides of the boat at an angle? How long is the boat, how wide? Got pictures?

I'm not sure how poly resin will react to depron, but epoxy and fiberglass cloth might do the trick for you. Anything you add to the boat will add weight....the idea is to "mitigate your damages" and choose the lightest alternative without it being too light. You do need some heft to keep it on the water.

Some more info might help come up with a solution.

How big is the prop?

Can you post some pics, maybe front, side and rear profiles?

You said it flips on a hard turn. Does it flip backwards or to the inside or to the outside of the turn?

You could go with either fiber glass or kevlar, or even just epoxy with no cloth at all. The thicker the cloth, the heavier the end result will be. A little added weight may be good for handling and stability.

Kevlar is the stuff bulletproof vests and flak jackets are made of. Kevlar is slightly less stiff than fiberglass, but much tougher and lighter weight.

It all depends on how heavy the cloth is to begin with and how you apply the epoxy. Epoxy is heavy in itself, so light, skim coats are a must.

Use a plastic body trowel to basically scrape the epoxy across the surface to leave a very thin coat.
