Built it from plans using Okuome plywood. Very intricate parts with the assembly sensitive to errors in cutting out the parts, but ultimately nothing that wood thickened epoxy and cloth can't cover over. pulling it all together was an exercise in slow, careful manipulation. One glued and glassed, the lines are quite beautiful. Any other flaws are covered by multi-colored exterior house paint job. The sand rubs it off and I put more on, so it is an evolving work of art.
For us bigger folks, the buoyancy in the rear of the boat is light, and the stern is almost immersed. Taking a set of plans and enlarging it by 8-10% would probably solve that. I saw one on-line that was enlarged in this way. On waves, though, it rides nicely and is sized fine.
I am now adding fins to the boat, as without fins the boat is perfectly willing to point and track in different directions.
Very fun boat, and for my son it will be a 9-10 rating when he grows into it.
