Default Help needed for Oar powered boat

Anyone come across or have experience building an oar powered boat. I am building a rowing galley that will have 12 oars on each side. I think that I have the mechanics worked out but I could use some ideas. Any help would be appreciated. Thanks

I saw a Viking ship at the Toledo show a couple of years ago but lost the pix in a computer crash. RCBM also had a feature in the boat. He used a belt drive on each side of the boat to control steering with each oar hooked up to pullies that each had an oar attached. Also at a later show there was a model of one of the first steam-powered boats that used a strange system using oars. Those oars were vertical.

Essentially, you want to attach the handles of your oars to the circumferance of a circle.
As the the handle moves up the rear edge of the circle the blade will be angled toward the bow of the boat. Then as the handle rises, the paddle will dip into the water. As the handle follows the circle up and forward, the paddle will be driven down and back, and then repeat the process.

The length and depth of the stroke will depend on where you place the fulcrum on the oar.

Thanks for the ideas. I thought that I could rig a similar system. Perhaps something that was belt driven and moved a piece of aluminum stock through a circular motion (translational?). My oar mounts would be spaced accordingly along the surface of the aluminum stock. As the motor would turn, the aluminum stock would move around pivot points on fore and aft pullies (driven by a belt). This would create a circular path to drive the oars. I'll experiment this weekend. Thanks again.

have pictures of a Viking ship by friend, unfortunately died some time ago. do not seem to be able to insert pictures into reply. Looked good on water. oars were operated by common beam with rotating pivots at ends (driven by geared motor)
