I didn't parasail but our table mate did and he loved it. At Castaway they take you out past the break water out in front of the ship. (we watched from our verandah at the end of the day).
Jack said that they put you in a sturdy harness, hook you up to the cable, you stand on a platform at the end of the boat and the next thing you know is that you are floating above the water.
