I like this; it's a Truc 12. Clean, simple and portable. I'd go for a self build option if they'd only make one, and given that this is by far the most popular thing I've ever posted, it seems I wouldn't be the their only customer! David
If you're too lazy to paddle your own kayak, the solar-powered SPK-1 outrigger can harness the energy of the sun to get you on your way. Three big solar panels on this kayak-mounted attachment feed power to a silent-running electric trolling motor with 36 pounds of thrust. On the next page, take a look at a detailed diagram of the SPK-1.
