@ John

Thanks for the kind words!

I only paddle twice. First was a little bit strange, not used to this kind of kayak. The paddle was on an open lake with some wind. I had trouble in maintaining the straight direction.
Second was on some channels and lakes on Delta of the Danube river. Was great. There was some wind but I had no problem.
Is not finished. Maybe in the Spring I will paint it. It is a little bit cold for more work for now. I will paddle it some more.

I didn't cover with glass the copper fittings on the inside, only some hot glue on inside. I didn't feel the need. Is very strong with only the hot glue and some epoxy grout on outside.

For sections I adapted a little bit from clc boats:
