Seems to work real easy! But having looked at the source code after conversion, looks like something only Kayakforum will directly support.

p.s. I too have no problem trusting Gail's drawings and measurements, and am inclined to support the theory - cynical as it may be - that only the dogs among paddles got given away to nosey strangers. Perhaps the best older info is in Nansen's watercolours from his book. He did stay awhile, got friendly with the people, and I suppose when these showed him their skills, it was done with the best tools they at the time had.
