The Atlantic 21 Inshore lifeboat was the first generation rigid inflatable boat (RIB), in the B-class series of Inshore lifeboats, that were operated around the shores of the British Isles and the Channel Islands by the Royal National Lifeboat Institution (RNLI), between 1972 and 2008. The Inshore boat was designed at Atlantic College in South Wales, the birthplace of the RIB, after which the craft is named. The college was also one of nine locations where the RNLI first established lifeboat stations using smaller inshore watercraft. Atlantic College Lifeboat Station was operated by the RNLI between 1963 and 2013. The development of the Atlantic 21 resulted in the larger Atlantic 75-class, with production beginning in 1993. The Atlantic 75 gradually replaced the Atlantic 21, with the majority of the ninety-six Atlantic 21 lifeboats retired from service by 2006. Just a handful remained on service into 2007 and 2008, with the last two Atlantic 21 lifeboats, at Enniskillen Lifeboat Station (Upper and Lower), both withdrawn from operational duties on 26 February 2008.

Description

The Atlantic 21 can be launched from a davit, carriage or floating boathouse depending on the location of the station and the available facilities. The lifeboat is a rigid inflatable boat (RIB), with the hull constructed of Fibre-reinforced plastic, subdivided into water-tight compartments, and manufactured at Halmatic Ltd. of Havant. The boats are then fitted out at the RNLI Inshore Lifeboat Centre in at East Cowes, Isle of Wight. A roll-bar is fitted above the engines, which carries an inflatable air-bag for self-righting, which can be inflated by a crew-member from a gas bottle should the boat capsize. The boat carries a variety of equipment which includes two VHF radios, first aid kit and oxygen, GPS navigation system, night vision equipment, self-righting system, anchor and various warps, toolkit, towing system, illuminating and distress pyrotechnics, spotlight, torches.
