dingy power
This is how it works:=
Off the transom is hung on a light weight rudder hinge, a piece of wood hung vertical with handle at the top into the dingy, used to swing back and forth, like an oar. The bottom end of the vertical wood that's in the water, is fixed a flexible conveyor belt type material, many flexible materials can be used, this drives the boat forward when the handle at the top is pulled back and fore. the length is atleast 24 inches, or longer and 6 inches wide or more. I feel that it could also control direction, but not as good as a rudder . ........... |

Two pull cables with pedal pads. Terry K |

I know that there are a lot of variables to consider, but generally what
kind of speed should I expect from this kind of system verses the level of effort? I tried it with the normal rigid rudder and didn't notice any significant boat travel. Anyone have a link to some design guidance? "rebel" wrote in message ...

Consider a scuba divers flippers around 18 inches long large type. ideal flexible material would be a tapering from thick to thin at end. [ not necessary, snake type action ] Regard stearing one sided strokes according to direction, when on course start full sweep. |

Harry Bryan has developed fin-propelled kayaks. The fin appears to be of
maybe 1/4" Lexan and is operated by foot pedals. "rebel" wrote in message ...
