Maui Ulua


William Manual in Maui is almost ready for a test sail in his new Ulua.  William added some extra curvasiousness to the iako along with a safety ama.

I wish there was an easy way to get thin lumber to laminate like that. One guy on the Wooden Boat Forum laminated kayak-proa akas out of plywood. I sent a message to ask how they worked out, but I never heard back.

The main point of curved lamination - especially in this case - is to have all the strength and stiffness of the wood fibers working for you. Veneer core plywood has almost half its layers running cross-grain; while the assembly might look similar, the strength would be lacking.

I plane pine down to 6-7 mm and this bends quite easy but the glueing this up is a mess and take a lot of glue.

I made hollow curved akas with 6mm ply sides and 10mm top and bottom ripped from 1" stock. But I wonder if 1 or 2 layers of ply would do instead? Stress is mostly longitudinal anyway in the outer surfaces of a beam?
