The biggest RIBs are also particularly good as dive boats. They also incorporate a deeper floor than most rigid hulled inflatables, for increased onboard security and drier ride. The first thing you'll notice about all inflatables is their incredible stability. Inflatables, with their big-volume buoyancy tubes, sit flat in the water and are almost impossible to tip. That's very reassuring if you've got newcomers on board, and even allows swimmers or divers to slide back on board without rocking the boat.
More buoyancy means bigger load-carrying capacity.
Inflatable boats have enormous reserves of built in buoyancy. With huge flotation tubes positioned on opposite sides of the hull, and in some instances with an inflatable V-keel as well, inflatable boats can carry very heavy payloads in absolute safety. For instance, the Virage range of sports boats features Zodiac's patented Futura speed tubes to produce amazing lift and stability. The big Zodiac rigid-hulled inflatable superboats are equally impressive. With deep V-keels up forward and flat planing sections aft they can produce an astonishingly comfortable ride in tough offshore conditions, yet maneuver with ease in the tightest dock or harbor.
