For a small fishing boat
I need info on a propulsion system based on a hand powered propeller / outboard drive system. No gas motor, just human power. Seems there used to be something that was similar to an out board that had nothing but perhaps a few bevel gears and a lever that functioned as a tiller that was jacked up and down for the power to spin the prop. Any body remember any details? thanks ! steve-----at----avertical------dot----com |

Why not try a YuhlooYuhloo An uleau is an oar with about a 15 degree bend in the handle perdendicular to the plane of the oar and a pivot at that point, which presents the oar blade sideways, perpendicular to the desired direction of travel. The end of the handle is tied by a piece of rope several feet long to the interior of the boat. Moving the oar handle sideways by pulling and pushing on the rope causes the blade, along with the bend and pivot, to work in the water like the blade of a propellor, equally to either side, "sculling" the oar. Each reversal of the handle causes the blade to pivot a few degrees, so the blade pushes or pulls the boat with each side to side motion. Manipulation of the handle permits steering. The blade is lifted from the water to enable coasting between strokes, if desirable. Pushing or pulling harder to one side or the other also enables steering. A rubber flipper stuck on a typical rudder may also serve, with technique. Terry K |

I've seen a lot of human powered stuff just recently in my search for
info on building my own paddleboat. You can get some ideas here; http://www.waterbiking.org/ http://www.humanpoweredboats.com The paddle ideas seems the cheapest, simplest and surest way of implementing human power, all it takes if you want to do it on the cheap is an old bycicle, maybe one or two extra chains, a couple of different size sprockets for experimenting and something to make the paddle out of (can be wood), if you wanted to get fancy you could try using the gears off a ten speed. |
