Seen some orientals propelling their small boats with a single oar 'yuloh' at the transom, on 'Z' motion.

Would there be an advantage of the oar paddle being flexible, as a fish/whale tailfin propulsion, not for 'Z' motion ?

It has been done already and it seems successful but I would say it could end up with fatigue at the point of flexing.

Neat ! Thank you !

What should be done is to have two other flexible blades attached to the boat so when the flexible oar is pulled through the water instead of the boat turning this way then that, that motion flexes the flexible blade and assists in the forward motion. I reckon you would triple the forward speed with the 3 blades used together.
