RHIB

A rigid-hulled inflatable boat, commonly abbreviated RHIB or RIB, is a small to mid-size craft featuring a solid, shaped hull surrounded by one or more inflatable tubes (sponsons). The rigid hull provides strength, seaworthiness, and planing efficiency, while the inflatable collar offers buoyancy, stability, and good load-carrying capacity. This combination allows RHIBs to operate in a wide range of sea states and conditions, including shallow harbors and tight spaces.

Construction and configuration typically involve an aluminum or fiberglass hull with removable or integral inflatable tubes made from Hypalon, neoprene-coated nylon, or PVC. Outboard engines are the most common propulsion, with some larger models using inboard/outboard setups. Power ranges from tens to hundreds of horsepower, producing high speeds that enable rapid response, troop insertion, or rescue operations. Tubes help preserve buoyancy and reduce capsize risk in rough water, while low weight and high power give strong acceleration and maneuverability.

Applications and operators span military, coast guards, police, and search-and-rescue services, as well as civilian roles such as offshore support, diving, and tourism. RHIBs are used for fast transport, surveillance, boarding operations, and emergency response. They come in a variety of lengths, commonly from about 4 to 12 meters, with configurations tailored to mission needs. Compliance with safety and regulatory standards varies by use and region; many RHIBs intended for life-saving or professional service may meet SOLAS, MED, or CE requirements.

Maintenance involves regular inspection of hull integrity, tube pressure and condition, engine servicing, and puncture repairs to ensure reliability in demanding environments.
