M_Boats: Sculling oar

Hi gang, Here is a website I found with instructions on how to build a sculling oar; and how it is used. I initially went to "sculling oars" and in poking around, this is the one I found. Knockabout Sloops: How to Build a *Sculling Oar* by Jerome FitzGerald <http://knockaboutsloops.blogspot.com/2008/08/how-to-build-sculling-oar-by-jerome.html> As you will see from his diagrams, the end of the oar that's in the water is bent downwards so that as you swing it back and forth it acts as a vertical paddle propelling the boat. I also found some YouTube videos that show Chinese boats using yulohs in action. Connie
