Why is a Rigid Hull Inflatable Boat (RHIB) most often the vessel of choice for Professional Mariners, Maritime Law Enforcement Agencies all over the world?
The OCM RHIB uses a unique, concave hull chine design. As it moves through the water and impacts waves, the concave chine acts to direct the water downward thereby creating extra lift and reducing the wetted surface and friction drag of the hull. The combination of lighter-weight and reduced friction, translates into increased overall top-speed with reduced fuel consumption and fuel cost and results in an increased overall operational range per gallon of fuel carried and consumed.
The inflatable tube-set provides the craft with wonderful lateral stability and abundant reserve buoyancy. Even when the vessel is deliberately overloaded to one-side with unevenly distributed weight, the air holding tube could then be forced by this weight to touch the water, but its inherent and abundant buoyancy prevents the vessel from tipping further or capsizing. To dispel a common misconception about RHIBS; when a properly designed RHIB is at rest or underway in nominal operating conditions, the tube-set does not contact the water except to deflect occasional sea-spray, and it is NOT required for buoyancy to keep the vessel afloat.
