my first attempt at kayak building has not gone well. i've been following the direction of chris kulczycki's book, "the kayak shop" well, the truth is, not following close enough. i've attemped to build a cross between the yare and pocomoke. i wanted the beam of the pocomoke 28 inches in the 16 foot yare. to add to the problem, i didn't use marine ply; i substituded birch 1/8 ply. i also used 3/8 by 3/4 hemlock for sheer clams. the hull went together well, but when i pulled it together for the deck things started to go wrong. with the deck beams in place the hull seems warped. i don't know if the sheers being the wrong size is the problem? i've considered adding more deck beam to straight the hull? i've also considered setting it ablaze and starting over. sincerely match and gasoline.
