: . . .I got my two layers of epoxy on the ouside and tryed
: the boat out. And realized I had made a really dumb mistake somehwere and
: the boat was leaking. So now I have filled in all my seams and the boat
: doesn't leak, but I think it might if I hit anything.

Well, don't hit anything. Seriously, if the seam construction on your stitch and glue is up to par then the panels are not going to fall off, or separate any great amount if you hit something.

You would have to hit hard enough to cause the fillets and tape to rip free from the wood, practically ripping the plywood apart. The destruction of the wood might actually cushion the impact so your body doesn;t take all the force -- kinda like crumple zones on a car. Those kind of impacts you try to swim away from, so you can go back to the shop and build another boat.

How long of a race do you expect to be in?

And how fast is it leaking?

If you are just getting a few drops inside, ignore them. If there are pinhole leaks from the stitching wires, plug them with epoxy coated toothpicks, and the problem is solved.

Your fillets and taping inside should have sealed all the seams. A layer of tape or thin glass strips on the outer seams should guarantee the wire holes are filled in. Two coats of epoxy on the plywood should keep water from penetrating through the wood. Not too many more areas where you can spring a leak.

Put a few gallons of water inside the boat and look for any places where water is coming out. There are your leaks. Plug them and be done with it.

If you still can't find your leaks, let it leak. If it is a short distance then you can bail out any water at the end of the race. If it is a long race, get a footpump, and use it occasionally.

Eventually you'll find where the water is coming in and do a good patch. Covering with just epoxy resin is not a good patch, but it may be all you need to do.
