Who has used a winch?

[madcityskier]

Anyone here ever do any riding on a winch? Guy I've been out with in Madison lately has developed a pretty cool winch system. I haven't had a chance to get a run with it yet, but I find the idea intriguing. I like the idea of making quick runs in areas not accessible to boats, or where boats are banned. I suspect that if a cop caught me trying to ride on a pond in a public park it could turn into a hassel. For that reason the electric seems like it would be superior to gas. Quiet and high amounts of instant torque seem like a great combo. I'm interested, but would like to hear of other people's experiences.
This is the link to the system I'm hoping to try out
