A few more points on the epoxy issue. 2 part epoxy is great stuff. I find that I like the 5 minute stuff due to my ADD[sm=bananahead.gif]I had to get some 12 minute stuff because it was all that was available at first but I didn't have good luck with it. It has very low viscosity until the 20 minute mark so it was running everywhere and leaving drip marks I had to wipe off constantly before they hardened.
As I mentioned I used generous fillets. The pic's make it looke like there is smooth lap joints but in reality there is an angular cavity that I fill with epoxy.
I have used strips of Styrene to fill huge gaps due to the conv kit fit-up.

I am no longer worried at all about the strength of the upper hull due to the epoxy hardening. I am a little worried because it now weighs 84 pounds
