Did they try it with a kite?
If you think for a moment I'm going to take time to watch a clip of someone abusing his Laser... You have another think coming.
I think he was a little bored.
It looks like an old wooden board and he probably trashed the laser that come with it along time ago.
If I am a little younger these tricks are chicken. I say little younger because I am a little older now. If only wake boarding is popular when I was younger. Still it's fun watching.
Frankly, once you get up, it's not that difficult.
Baydog, this is a family blog.
That might actually be less abuse to the daggerboard than my current method of using it to find bottom in shallow water. (In deeper water, of course, I employ the mast in that task.)
