Most rowers know that sculling is what you do with a pair of sculls (oars), one in each hand, but sculling also means rowing using one oar off the transom, as shown in this video. I shot this video in Mystic, CT. while sculling my rowboat (I won't call it a scull) using my feet. The rowboat in the video is a Swampscott Dory, which can also be sailed. By the way, we will be displaying at the WoodenBoat Show in Mystic June 24-26, 2016.
Scull is a weird word with so many meanings that it's almost meaningless. But in the nautical sense it can mean: a method of rowing, a boat for rowing, or an oar. Or a different method of rowing.
Most of us have heard the statement, "You can scull your scull with a pair of sculls." or something like that.
Well, I would add to it: "or a single scull."
