''Tamar''-class lifeboats are all-weather lifeboats (ALBs) operated by the Royal National Lifeboat Institution (RNLI) around the coasts of Great Britain and Ireland. They have replaced the majority of the older ALBs. The prototype was built in 2000 and 27 production boats were introduced between 2006 and 2013. The class name comes from the River Tamar in south west England which flows into the English Channel where they were manufactured by Babcock International Group. ==History== Since 1982 the RNLI had deployed lifeboats at stations which launched their boats down slipways or needed to operate in shallow waters. The organisation desired to increase the speed and range of their operations so introduced faster and boats starting in 1994 at locations where they could be moored afloat. They then needed to produce a boat with similar capabilities but with protected propellers and other modifications that would allow it to be launched on a slipway. Although nominally the replacement for the ALBs, only twenty seven ''Tamar''s have been built (compared to forty ''Tyne''s). The remaining ''Tyne''s will be replaced by boats. The prototype ''Tamar'' was built in 2000 and was used for trials until 2006. It was sold in December 2008 to Kent Police, becoming Princess Alexandra III, the force's permanent maritime vessel operating out of Sheerness. The first production boat, ''Haydn Miller'' entered service at in March 2006. A few of the early boats suffered problems such as fuel leaking under the floor of the engine room around hydraulic lines. These boats were recalled and the problems rectified. The 27th and last ''Tamar'' Class lifeboat, allocated to The Mumbles, was launched 12 March 2013 in Devonport Dockyard and after sea trials was handed over to the RNLI on 21 May 2013.〔http://www.babcockinternational.com/media-centre/last-of-27-tamar-class-lifeboats-delivered-by-babcock-on-time/〕〔http://rnli.org/NewsCentre/Pages/Praise-for-Babcock-as-final-RNLI-Tamar-class-lifeboat-is-completed.aspx〕 10 lifeboat stations keep ''Tamar''s moored afloat, 13 launch them down slipways, and the remaining 4 form a Relief Fleet to cover when boats are unavailable for service. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tamar-class lifeboat」の詳細全文を読む スポンサード リンク
