    Keep in mind that's a flat water boat, more canoe than kayak. Because of its open design, it's not suitable for seafaring.

    Yeah, that is a problem. Maybe there is possibility to cover it somehow. I did find similar from Hobie Kayak, they are not so open, but still open. They are selling these Hobies in Finland, so I have to go check it out.

    We lose an occasional kayaker in these waters. Mostly they just disappear. Sometimes the boat floats in, sometimes not.

    Hmmm. I'll admit right off the top this idea probably won't work, but....
    what about pedals on a sailboat? (Tom, when you finish wiping the tears of laughter from your eyes, you'll realise this was presented in the spirit of the brainstorming, where ideas are accepted without critique.)

    No, I don't mean I'm planning to stick a bicycle in the cockpit and hook it up to the prop. (Although, that might be slightly less crazy on a light multihull than it would be on a heavy displacement cruiser) I'm thinking of those little hand powered flashlights - could that be done on a larger scale with legs instead of thumbs, and used to power a boat's lights and navigational instruments in an emergency? Sure, the average person would have trouble keeping a 60 watt bulb lit longer than five minutes, but think of ultra efficient LEDs and a fit cyclist who would happily spin for an hour to save his life.


    PS: No, there's nothing special in my coffee this morning. And yes, I should know by now that if I think it's silly, it's quite likely completely nuts. But sometimes, ya just gotta ask anyway.

    Many older sailboats used sweeps (long oars) for axillary propulsion. Sailboat hulls are easily driven, so it doesn't take much power unless you are working against wind, waves, or current.

    With human powered propulsion you typically want to stick with a simple mechanical path, such as that used on a bicycle. Anything else tends to have too many losses.
