In order to defy gravity without insulting it outright, sightseer duos ride the breeze in a two-man skyhook over the water while securely tethered to winch boat. Launching from the deck of the vessel allows para sailors to stay dry in-flight, unless they signal the captain for a reverse-Achillean dip. Once airborne, fliers surf the air waves suspended at heights of up to 500 feet, the same height at which a common weather balloon begins to resemble a dinner plate. Many parasailing trips coincide with local dolphin feeding patterns, giving hobby marine biologists the chance to survey sea mammal cafeteria politicking from above.
