The ''Shannon''-class lifeboat (previously FCB2 – Fast Carriage Boat 2) is the latest class of lifeboat currently being deployed to the RNLI fleet to serve the shores of the British Isles. The ''Shannon'' class is intended to replace the Mersey class carriage-launched lifeboat and, with the completion of the Tamar build programme, the remaining Tyne-class lifeboats. ==History== The experimental boat, named ''Effseabee Too'' underwent sea trials during 2005–2008. It is based on a Camarc Pilot vessel design, with a fibre reinforced composite hull, powered by twin water jets. It had a top speed of approximately , but was planned to be rated down to 25–27 knots when the final design was put into production. In 2008, FCB2 development was delayed due to hull shape issues, as trials showed crews would be subjected to unacceptable shocks and excessive horizontal shaking in high seas. The RNLI indicated that the project would be extended by at least three more years to research a new hull shape. The Shannon class uses similar Systems and Information Management System (SIMS) technology to that of the Tamar class lifeboat so that crew members can operate all of the boats systems collaboratively without leaving their seats. Crew seats are also similar to the Tamar, sprung to reduce the shocks in heavy seas. 〔(RNLI FCB2 newsletter )〕 In April 2009 it was announced a new hull had been chosen. The Shannon class prototype boat was completed late 2011 and scheduled for active service as of mid-2013. In April 2011 it was announced the class would be named after the River Shannon, the longest river in Ireland. This is the first time that the name of an Irish river has been used for a class of RNLI lifeboat.〔 After boatyard acceptance in March 2012 the first of the fleet went through sea acceptance trials in 2012. All hulls are moulded by SAR Composites and up to ON1318 were fitted out by Berthon Boat Co. Lymington Hampshire From ON1319 fitting out will be progressively switched to the RNLI All-Weather Lifeboat Centre at Poole, to which hull moulding will also eventually be transferred. 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「Shannon-class lifeboat」の詳細全文を読む スポンサード リンク
