MULTIFUNCTION, an easy way.

We need, normally, an steering system, an auxiliary oar and a propulsion system. What if we use all toguether, in the same system? Is nothing complex, if we try to sintetyze.

The chinese yuloh can be modified for this purpose. The blade can be done vertical and the arm flexible, so this way we have all the system and is too simple. Simpler is smarter, if it works.

The blue shark tail size is something like the half of his lenght, and in the red tuna we can talk about one third. The difference is this shark's shape is trimmer like a narrow planning hull and the tuna looks more like a displacement hull, but the both reaches fast speeds. This bring idea about the lenght of the oar's blade.
