The wind catches a sail, and suddenly the 41-foot vessel springs to life. The sail boat's hull cuts across the water at increasing speeds, racing alongside city skylines and a mangrove-covered shore. The man at the helm is Captain Carlin, and he guides the vessel with a confidence and ease that can only come from more than 45 years of sailing experience. The captain's charters take up to six passengers through the Biscanye Bay: a shallow estuary home to pelicans, manatees, and retired leviathans. Along the way, groups can sip wine as they bask in the midday sun or the soft glow of an ocean sunset.
