Cable skiing is a way to water ski (or wakeboard), where the skier's rope and handle are pulled by an electrically driven cable, whereas traditionally a waterskier is pulled by a motorboat. The mechanism consists of two cables running parallel to one another with carriers between them. The carriers are metal plates with hooks on them which allow the tow rope to be attached and detached easily without shutting the system down. The cable is generally suspended 15-20 feet (5-7 metres) above the water. This makes for a different feel then when riding behind a boat, whether wakeboarding or water skiing.
