Has anyone ever cobbled together an off-season paddling machine? The store boughts are thousands of $$$$. I'd be very interested, seeing as how I had major rotator cuff surgery to my shoulder a few weeks ago. Doc says no kayak till October! This is my third repair, so I think I'll do everything he says this time. That's why I decided to build a boat if I can't paddle one. My plans from Orca should be here any day. I'm pretty excited about it.
