Description

Siyay is a Type 400 BHC AP1-88/400 hovercraft, the second of two vessels constructed for the Canadian Coast Guard. [1] [2] Siyay, which was constructed out of aluminium, has a standard displacement of 36 tonnes (35 long 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 Palfinger - PK3000M 5,000-kilogram (5.0 t) crane. [2] [3]

The hovercraft is powered by four Caterpillar 3416 TTA diesel engines turning two controllable-pitch propellers creating 2,818 kilowatts (3,779  hp ). [2] [3] Siyay has a maximum speed of 50 knots (93 km/h; 58 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 vessel has a complement of 7 with two officers and a five person dive team. [3] [lower-alpha 2]

Construction and career

The contract to build Siyay and sister ship Sipu Muin 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] Siyay was launched in 1998 [3] and completed in December of that year. [2] At the time of construction, Siyay and Sipu Muin were the largest diesel-powered hovercraft in the world. [1] The name Siyay is taken from the Salish word for friend. [3] Siyay entered service in 1998 and is based at Richmond, British Columbia. [3] Siyay is predominantly used for servicing navigational aids and search and rescue duties. [1] The vessel is registered in Ottawa, Ontario. [3]

In July 1999, Siyay struck a rock breakwater and the craft sustained significant damage. [4]

In September 2014, Siyay underwent unscheduled maintenance, forcing the Canadian Coast Guard to redeploy other vessels to cover for the loss. [5] However, by the end of the month, Siyay was back in service, rescuing seven people from a sinking fishing boat off the coast of British Columbia. [6] In 2015, Siyay was taken out of service for a refit at the Seaspan shipyard, returning to operations in May 2016. [7]
