The word "snuba" hasn’t yet entered mainstream English, but it soon might. A cross between snorkeling and scuba diving, snuba is one step closer to the fascinating undersea world scuba divers have always raved about—the view, the nearness, the complete entry into that foreign space. And there’s no need to surface continually for air. Instead of donning tanks, divers strap on masks, fins, and small weights, and are connected by a 20-foot breathing hose and harness to an air tank floating on a raft above (each raft has hook-ups for two divers). As you snuba, the lightweight raft moves with you. You can stay down and explore the shallower depths of the ocean floor and reef until your skin wrinkles, without lugging around all that diving equipment. It’s designed as a preliminary experience, to ease the fearful into the underwater environment, and is safe for everyone who’s ever wanted to dive but never had the time or means to take a course. A guide accompanies all divers, and kids eight and older are welcome.
