Electric RIBs are rigid inflatable boats fitted with battery-electric propulsion in place of conventional petrol or diesel outboard engines. The type is used primarily as a yacht tender, harbour runabout, or short-range patrol and rescue craft, where operating range on a single charge is sufficient and where low noise and zero local emissions are operationally or regulatorily important.
Hull and tube construction follows standard RIB practice: a fibreglass or aluminium rigid hull with hypalon or PVC inflatable tubes providing buoyancy and impact resistance. Electric motors are installed as outboard units or as inboard pod drives, with lithium-ion battery packs integrated into the hull. Usable range on current production models is typically 15–40 nautical miles depending on speed and load — adequate for tender duties and day use in protected waters, but a practical constraint for offshore or extended coastal use. Charging is done via shore power; charge times vary from two to eight hours depending on battery capacity and charger output.
Top speeds on electric RIBs range from 20 to over 35 knots on performance-oriented models. The torque characteristics of electric motors deliver responsive acceleration, and noise levels under power are substantially lower than combustion equivalents — an advantage in noise-sensitive anchorages and marine protected areas. Maintenance requirements are reduced by the absence of engine oil, fuel filters, and cooling system components. Battery replacement cost and lifespan remain the primary long-term ownership consideration.
