The Atlantic 85 lifeboats serve the shores of the Ireland and the UK and are known as inshore lifeboats (ILBs). The Atlantic 85 is the third generation Rigid Inflatable Boat (RIB) in the B-Class series, developed from the Atlantic 21 and Atlantic 75 by the RNLI design team in Cowes, Isle of Wight.
The Atlantic 85 can remain on service for three hours at full speed. In the event of a capsize the Atlantic can be righted by activating a gas buoyancy bag which will in turn right the lifeboat. The Atlantic can be launched by a number of methods which include Tractor and Drive On Drive Off carriage, slipway and davit launching.
The boat’s rigid hull is constructed of Carbon fibre laminate, with a foam core, and the sponsons are are extremely durable and made of Hypalon coated Nylon material. The twin 4-stroke Yamaha outboards each producing 115 hp are modified at the RNLI’s Inshore Lifebaot Centre at Cowes to prevent water entering in the event of a capsize. This allows them to be restarted within seconds after the vessel has been righted.
