Does anyone have a good reference for building a feathered kayak paddle? I've got a collapsible paddle that came with the POS inflatable I used in Alaska... the paddle was serviceable enough and came home, the kayak did not. But if I'm building a wooden kayak, I feel like it would be nice to have a wooden paddle to go with it. But I like about 20-30 degrees of feathering to my paddle... not so easy to make as a flat one! Thanks!
