WNeptune's Navy is the name that the Sea Shepherd Conservation Society uses to refer to the ships it operates. Most of these vessels are used to disrupt or hinder fishing, whaling or sealing operations that the group considers illegal.
WMY Ady Gil was a 78-foot (24 m), wave-piercing trimaran originally created as part of a project to break the world record for circumnavigating the globe in a powerboat. Powered by biodiesel fuel, the vessel was also capable of running on regular diesel fuel. It used other eco-friendly materials such as vegetable oil lubricants, hemp composites, and non-toxic anti-fouling, and had features such as bilge-water filters.
WThe MY Bob Barker is a ship owned and operated by the Sea Shepherd Conservation Society, named after American television game show host and animal rights activist Bob Barker, whose donation of $5 million to the society facilitated the purchase of the ship. She began operating for the group in late 2009 / early 2010 in its campaign against whaling by Japanese fisheries. In October 2010, Sea Shepherd stated that Bob Barker had completed a major refit in Hobart, Tasmania. Hobart is now the ship's honorary home port.

WMY Sam Simon is a vessel of the Sea Shepherd Conservation Society fleet, named after American television producer and writer Sam Simon, who donated the money to purchase the vessel. The ship's identity was kept secret, to be revealed when she met the Japanese whaling fleet in 2012, but was identified when her registration was discovered on the Australian Maritime Safety Authority's list of registered ships.
WSea Shepherd II was a former 657-ton fishing trawler owned by the Sea Shepherd Conservation Society. Sea Shepherd II was registered in the UK port of Glasgow. The ship took part in numerous campaigns, most of which were anti-sealing campaigns in Canada. She was acquired in 1980 with money received for the film rights to the story of the Sierra campaign, and replaced the nearly identical Sea Shepherd I. Sea Shepherd reports that equipment from the ship was sold in 1992 and the hull was sold later. In 2004 the ship was considered derelict and in danger of sinking resulting in the vessel being broken up at Esquimalt graving dock in July 2004.
