Neptune's Navy

[1] The Sea Shepherd vessels (Neptune’s Navy) are used to disrupt or hinder illegal, unreported and unregulated fishing (IUU), whaling or sealing operations.

Pete Bethune, the operator of the vessel, said that an agreement was reached with Sea Shepherd for the boat to adopt a support role.

[5] On October 17, 2009, the Earthrace was presented to the media with a new black paint job, and renamed Ady Gil, after the name of a major sponsor.

[13] In response to this incident and new tactics employed by the Japanese whaling fleet, Paul Watson has stated that he intends to procure more vessels to prevent themselves being outnumbered and shorthanded in future engagements.

"[16] As of 2023[update], the conservation society operates many ships worldwide, the M/Y AllanKay, the M/Y Triton, the M/Y Conrad, the MY Age of Union (formerly the MY Sam Simon), the RV Martin Sheen, the MY Jairo Mora Sandoval, the M/Y Emanuel Bronner, M/Y Seahorse, and the M/Y Ocean Warrior.

[33][34][35] Because of what happened with the Brigitte Bardot, Sea Shepherd has transitioned away from yachts and trimarans for fast patrol boats, cutters, and catamarans to modernize its fleet.

[40][41] The Ocean Warrior is the current flagship, it has four engines capable of a maximum speed of 30 knots (56 km/h), so it can outrun any ship in Japan's whaling fleet; it is also equipped with additional long-range fuel tanks.

On September 17, 2020 Sea Shepherd acquired the MY Conrad to replace the Bardot and the Alchemy for work in the Mediterranean because of the cost to ship those vessels there because of the pandemic and because of maintenance.

Sea Shepherd plans to outfit the vessel for campaigns in Mexico to save the Vaquita and to stop driftnetting in the Gulf of California and in Galapagos.

[44] The group has also operated smaller boats in its campaigns including jet skis, Delta RHIB and Zodiac inflatables deployed off of the larger vessels.

The vessels being engaged in controversial activities has caused registration issues with multiple governments, and the ships of the fleet have flown the flags of several different nations.

"[55] The International Merchant Marine Registry of Belize withdrew the use of the nation's flag after finding the Farley Mowat was not being used as a pleasure craft and stated that "it could not condone acts that threatened life and property at sea.

"[56] The Mohawk Traditional Council of Kahnawake offered support and flags of the Iroquois Confederacy to fly on the Farley Mowat and the Robert Hunter.
