USCGC Anacapa (WPB-1335) is an Island-class cutter of the United States Coast Guard. Her class of ships were built in the 1980s and early 1990s to replace Cape-class cutters. The ship is named for Anacapa Island.

Anacapa's homeport in 2012 was Petersburg, Alaska.[1] She sank the Ryou-Un Maru in the Gulf of Alaska on April 5, 2012.

Design[edit]

The Island-class patrol boats were constructed in Bollinger Shipyards, Lockport, Louisiana. Anacapa has an overall length of 110 feet (34 m). It had a beam of 21 feet (6.4 m) and a draft of 7 feet (2.1 m) at the time of construction. The patrol boat has a displacement of 154 tonnes (152 long tons; 170 short tons) at full load and 137 tonnes (135 long tons; 151 short tons) at half load. It is powered two Paxman Valenta 16 CM diesel engines. It has two 99 kilowatts (135 PS; 133 shp) 3304T diesel generators made by Caterpillar. Its hull is constructed from highly strong steel, and the superstructure and major deck are constructed from aluminum.[2][3]

The Island-class patrol boats have maximum sustained speeds of 29.5 knots (54.6 km/h; 33.9 mph). It is fitted with one Mk 38 25 mm chain gun autocannon and two Browning .50 Caliber Machine Guns. It is fitted with satellite navigation systems, collision avoidance systems, surface radar, and a Loran C system. It has a range of 3,330 miles (2,890 nmi; 5,360 km) and an endurance of five days. Its complement is eighteen (three officers and fifteen crew members). Island-class patrol boats are based on Vosper Thornycroft 33 metres (108 ft) patrol boats and have similar dimensions.[2][3]

USCGC Anacapa directs streams of water into the Japanese derelict Ryou-Un Maru to sink it after shelling it. Holes from the 25 mm cannon are clearly visible in the side of the boat.

Incident[edit]

On 5 April 2012, the Anacapa assessed the derelict 165 ft Japanese squid fishing boat Ryou-Un Maru. It had been washed away from its mooring in Aomori Prefecture, Japan, by the March 2011 Tōhoku earthquake and tsunami, and had drifted unmanned for more than one year across the Pacific Ocean before it was discovered.[4][5] The Anacapa fired on the ghost ship with its Mk 38 25mm autocannon, holing and eventually sinking it with fire hoses in approximately 1,800-metre (6,000 ft) of water in the Gulf of Alaska 180 miles (290 km) off the coast of the Alaskan Panhandle.[6]
