No it's not from a kit. I copied the little drawing picture published by Sea Kayaker Magazines Avalon Viviane rewiew in April 2000!
Just enlarged drawing 10 times larger to get shapes for plywood.
The rudder has two layers of rubber sheet and is flexible enough to paddle without the risk of damage.
The building was guided by Nick Schades book; The Strip-Built Sea Kayak: Three Rugged, Beautiful Boats You Can Build.
