Underwater sculling

On a recent visit to Partridge Lake in New Hampshire I was privileged to participate in what may be the first instance of underwater sculling. The vessel was a vintage aluminum Grumman canoe filled with water, but still floating with us in it due to buoyancy tanks. Because the canoe has no rowlocks it required two people to row - I played the role of rowlocks, also providing some counterpull on the strokes, and my friend was the oarsman. It was hard work and very slow compared to the real thing, but amazingly it worked and naturally it was insanely silly to participate in. Watch the full movie here.
