The Response Boat – Medium (RB-M) is a utility boat used by the United States Coast Guard. It is a replacement for the Coast Guard's retired fleet of utility boats (UTB), which had been in use by the Coast Guard since the 1970s. The Coast Guard plans to acquire 170 of these RB-Ms over a 6–10 year period. The boats will be built by Kvichak Marine Industries of Kent, Washington and Marinette Marine Corporation of Marinette, Wisconsin. According to the US Coast Guard, "While primarily a Search and Rescue (SAR) asset when the 41' UTB was first fielded, the evolution of missions has increased the requirement to perform many missions including Recreational Boating Safety (RBS), Marine Environmental Protection (MEP), Enforcement of Laws and Treaties (ELT), Ports, Waterways, and Coastal Security (PWCS) and Defense Operations (DO), including those traditional missions associated with Homeland Security."〔(【引用サイトリンク】website=United States Coast Guard )〕 ==General characteristics== The boat has a deep-V, double chine hull, which provides a balance of performance and stability. The vessel is self-righting if it capsizes in rough seas. Below the pilot house are six compartments: * Lazarette *Auxiliary machinery compartment *Engine room *Survivors' Compartment *Forepeak *Head (Sources:) 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「Response Boat – Medium」の詳細全文を読む スポンサード リンク
