Located in the shadow of the Marriott hotel, Clearwater Jet Ski and Parasail outfits beachgoers with the equipment to safely speed across or sail above the waves. Its three-seater jet skis kick up massive wakes as they roar over the sapphire surface of the water, and tandem kayaks trundle along. Staff-operated speedboats tow parasails behind them, passengers getting a seagull’s view of the waves and a firm understanding of how silly the dog paddle looks from a distance.
