Beauty! I've built one, higher volume baidarka from Wolfgang Brinck's
book, and I'm thinking about what the next one will be, after me and my
girlfriend get her pygmy coho finished. Might try a more
layable-backable baidarka. How did you do the rear deck? Did you just
run the deck ridge over the last two or three deckbeams?
