Rigid inflatable boat
A rigid inflatable boat (RIB), also rigid-hull inflatable boat or rigid-hulled inflatable boat (RHIB), is a lightweight but high-performance and high-capacity boat constructed with a rigid hull bottom joined to side-forming air tubes that are inflated with air to high pressure to give the sides resilient rigidity along the boat's topsides. The design is stable, light, fast and seaworthy.
