The RPC12 (''Remorqueurs Portuaires et Côtiers de 12 tonnes de traction au point fixe'', "Harbour and Coastal tugboat, 12-tonne bollard pull") is a type of harbour tugboat operated by the French Navy. They utilise Voith propulsion to develop a 12-tonne bollard pull.〔 The RPC12 has been declined into three sub-types: the original version, called "Type A" (comprising ''Fréhel'' and ''Saire''), was designed as a dual-purpose tugboat capable of supporting shipping operations both in harbours and off the coast. After the two first units, the design was simplified, while retaining most functionalities, to reduce cost, yielding the "Type B" (comprising ''Armen'', ''La Houssaye'', ''Kéréon'', ''Sicié'' and ''Taunoa''). The nine remaining units constitute the RP12 type, which is further simplified to operated only within harbours (comprising ''Lardier'', ''Giens'', ''Mengam'', ''Balaguier'', ''Taillat'', ''Nividic'', ''Port Cros'', ''Le Four'' and ''Eckmühl''). Because of these differing capabilities, the RPC12 of both types are classified "auxiliaries", with an "A"-prefixed pennant number, while the RP12 are considered "yard vessels", with the corresponding "Y"-prefixed pennant numbers.〔 The latest in the series, ''Rascas'', is an improved high-sea ship with better sonic isolation and air conditioning, or use in tropical waters,〔 and a different radar.〔 File:Armen-IMG 9713.JPG|Profile view of ''Armen'' undergoing repairs, with her Voith Schneider Propellers clearly visible under the hull File:Armen-IMG 9707.JPG|Detail of ''Armens propellers ==Ships== 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「RPC12」の詳細全文を読む スポンサード リンク
