I did not see this done but a guy called Jeff Sweeny did it at one of the 1st SUP demo days at Torquay with a double ended Tahitian paddle. This paddle was too short and he had to get on his knees and paddle into the waves Kayak style untill he got speed and then jumped to his feet apparently it was vey effective.
I have experimented with a home made double ended paddle that is one third longer than normal made from cedar. It has handle holes cut in both ends.
At this stage I have only played with it on the river but i my pinion it has merrit!
Patent pending lol
