After building three Pygmys, I have recently branched out to build a bidarka at the Skin Boat School in Anacortes. It was a very worthwhile project, giving me significant broadening regarding kayak possibilities. Every kayaker should consider it. You can typically finish a bidarka in 6-9 days at the school.
As for the Pygmys, construction tips in the Tern thread apply equally well to the Osprey thread, and vice versa. Likewise, there are unique tips that apply to the particular boat. What I’m saying here is you should glance through both threads and the “Best Tips” page, no matter what Pygmy you are buiding.
