Sipu Muin is a Type 400 BHC AP1-88/400 air cushion vehicle (ACV)orhovercraft, the first of two vessels constructed for the Canadian Coast Guard.[1][2] Sipu Muin, which was constructed out of aluminium, has a standard displacement of 36 tonnes (35long tons) standard and 70 t (69 long tons) at full load and measures 70 net tonnage (NT).[1][2][3] The hovercraft is 28.5 metres (93 ft 6 in) long with a beam of 12 m (39 ft 4 in). The vessel has a main deck cargo capacity of 110 m2 (1,200 sq ft) and a well deck measuring 8.2 m × 6.4 m (26 ft 11 in × 21 ft 0 in), serviced by a Polar Crane 5,000-kilogram (5.0 t) crane.[2][3]
The ACV is powered by four Caterpillar 3416 TTA diesel engines turning two controllable-pitch propellers creating 2,818 kilowatts (3,779 hp).[2][3] Sipu Muin has a maximum speed of 48 knots (89 km/h; 55 mph) and a cruising speed of 45 knots (83 km/h; 52 mph). The vessel has a range of 300 nautical miles (560 km; 350 mi) with the endurance of one day. The hovercraft has a complement of 7 with two officers.[3][b]
The contract to build Sipu Muin and sister ship Siyay was awarded in May 1996 to GKN Westland. The two hovercraft were built by Hike Metals & Shipbuilding Limited at their yard in Wheatley, Ontario.[2] Sipu Muin was launched in 1998[3] and completed in August of that year.[2] At the time of construction, Sipu Muin and Siyay were the largest diesel-powered hovercraft in the world.[1] The name Sipu Muin is taken from the Miꞌkmaq phrase meaning "river bear".[3] Sipu Muin entered service in 1998 and is based at Trois-Rivières, Quebec.[3] Sip Muin is predominantly used for icebreaking duties in the Saint Lawrence River and St. Lawrence Seaway[4] along with servicing navigational aids and search and rescue duties.[1] The vessel is registeredinOttawa, Ontario.[3]
Beginning on 10 May 2016, the ACV underwent a six-month refit at Réparations Navales et Industrielles Océan in Quebec City, Quebec. The modernization included hull repairs and modifications to the pilothouse. The electronic navigation suite was upgraded and the fuel bladders and skirting replaced.[5]
