Canoe rudder?

This article may be of interest. I like it a lot but am more of a fan of gravity hold down or spring hold down systems rather than a pull up and pull down rope.

Works for a surfboard fin
Might work for a rudder. Fin from an ikea cutting board http://www.tobiasherold.de/sup-stand-up-paddling/ikea-hack-sup-finne-bambus-schneidebrett/#lightbox-gallery-3/5/

Both very good write-ups, lots of info in both of those pages.

That watertribe rudder looks very intriguing, wish I had seen that b4 I started on this project. Looks like they had some things figured out that I had to learn by tinkering. There is alot of good info there about blade shape also.

Does anybody know the length/width of the Seawind or Monarchs rudders blades? I think they are about the same. How much runs underwater?

Thanks.
