Anybody know how its done? some places I've seen make it look like you actually just get towed behind the jet ski, but others make it look like you just have the jet-ski drive by and surf its wake. Here's what the 2006 wavesportcatalog says: \"Big waves are ephemeral, but jet-ski and lake are consistently available. Dan Blackburn works on techniwue and style at 30 mph., accurately simulating the big wave bounce.\" There are several pictures of this, and in none of them are they holding tow ropes.
