i think the fin is made of silicone rubber and whats happening here is as the tip of the fin is breaking the sound barrier a time space warp is occuring and what your looking at is the tip of the fin moving between the past and the future as it crosses the screen... Freaky stuff hey!
Actually I retract my explanation...Alfredo's is more plausible.......
I think I agree with your explanation, sort of. I think it also might be an artifact of the compression algorithm used for video compression. I would expect a fin that moves like that in free air wouldn't be much use in the water.
Oh hang on, Alfredo said 'time space warp'... I also retract my statement. It has to be a time space warp. How else could they be showing us 2010 sails? It's still 2009!
