Wakeskating is really like a cross between wakeboarding and skateboarding. It is done behind a boat at about 20 mph on a 60 to 70 foot rope. It is a relatively new sport and has only been around about 5 or 6 years. There are only 4 or 5 wakeskate companies.
I don't have much to explain about wakeskating, except you need to try it. It is the best watersport ever. Yea. You have got to do this stuff.
