Not so easy beacuse, we got our first snow today and the canoe is on top of my garage roof. When a fine day comes by I'll try to climb up there. The largest cracks is/was located between the breasthook and siderails right where this picture shows. I glassed the entire area to repair it. There are so...

Last year I built a cheap canoe (just as a test) using polyester resin. Everybody told me what I already knew, that It will crack. I have to admit I was curious since I really built it well (except using polyester). To those of you that still feel a doubt and believes that polyester could work. It d...

Thanks for all replies. I was in contact with a epoxy manufaturers laboratory and they basically say. With the right process in a laboratory environment it can be done. But chances are way to big that it will fail and it should be considered a very complicated method that requires both resources and...

According to my theory, it does! I'm into building a model to study the flow but I have my theories. I believe that the water closest to the hull bottom moves sideways very fast. creating a sort of vortex whereas the underlying water layer stands still. The diameter of this vortex is logically much ...

I have noticed that most commercial boats on pictures seems to have their bottom structure (strakes), of some kind pretty straight along the bottom. But the water doesn't move in that direction at all from what I understand. Near the front the water seems to move very much sideways hitting the strak...

I feel too that the bonding to ply should be superior. But then again, there are sportscars with aluminium structures bonded by nothing more then epoxy. Not to mention some boeing airplanes where the alu wings actually are glued with epoxy. I did a little "web" research outside the boat in...

I'm fully aware of the oxidation problem with aluminium and the resolving. Besides that, what's your opinion on building the hull in aluminium joining it to plywood framing using the epoxy filleting tecnique? I'm building a hull in alu right now but I want to use ply for the entire internal structur...
