We had two on board and they were great fun. Paddles fold, pedals remove in 15 seconds. Great exercise and with the turbo fins we could cruise
at 4-4.5 knots and cover long distances. Great for exploring, fishing
and even have a sail kit if you want get off your sailboat and sail some more.
Make sure you have storage worked out. Alas the ones that I purchased were 13 ft long and slightly too long to store inside when away from the mother ship. But no worries even though they were expensive I sold them in a day for $200 more than I bought them for.
