The dolphins are released. Guatemala officially thanks Sea Shepherd for the intervention.

July: The Sea Shepherd II departs for Trinidad to patrol for Taiwanese driftnetters. Near Barbados, a Taiwanese driftnet boat is discovered.

March: The Sea Shepherd II and the Edward Abbey intervene against tuna seiners killing dolphins in the Eastern Tropical Pacific and chase them from the area.

Because of this, Captain Watson entered without a declaration on a Sunday. The repairs were done over the next three days without Mexican detection. Upon discovery by the authorities, the Edward Abbey let the lines go and sped from the harbor faster than any of the Mexican Navy pursuit vessels.

The Japanese government officially complains to the U.S. State Department. Returning to the mainland, the Edward Abbey is boarded by the U.S. Coast Guard. Captain Watson welcomes the investigation and gives the Coast Guard officers complete video documentation of the action. Japan withdraws the official complaint.

September: Sea Shepherd crew continues to monitor and document illegal driftnetting operations out of Kaohsiung, Taiwan.

Upon arrival on the Tail of the Banks outside of Canadian waters, the Cleveland Amory is met by Canadian government vessels and police and shadowed closely. Captain Watson is very much aware that he and his crew are under surveillance when he orders the Cuban drag trawler Rio Las Casas to pull up her nets and return to Havana. The Cuban complies but is informed by the Canadian Department of Fisheries that the Cleveland Amory has no authority to give such an order. Captain Watson retaliates by pulling alongside the Cuban trawler and instructing his crew to toss stink bombs onto the deck of the Rio Las Casas. Captain Watson then cuts the trawl. The Cubans retreat from the Banks. The Royal Canadian Mounted Police inform Captain Watson that he is under arrest. He ignores the order and makes a course to the Nose of the Banks where he orders a Spanish dragger off the Banks. The political controversy results in ten Cuban drag trawlers departing the Banks and returning to Cuban. Their reported losses exceed thirty five million dollars. The Mounted Police respond by boarding the Cleveland Amory and arresting Captain Watson outside the two-hundred mile limit. Captain Watson is charged with three counts of criminal mischief and the Cleveland Amory is brought into St. John's Newfoundland under guard.

August: To avoid the harassment and bureaucratic obstacles involved in getting the Cleveland Amory released, Captain Watson sells the ship to a private buyer.

July: The Sea Shepherd vessel Sirenian goes to British Columbia to document the opening of the salmon fishing season, the lack of fish, and ongoing dispute between commercial, sport, and native fishing interests over who was at fault. The Royal Canadian Mounted Police follow the Sirenian with two fast catamaran patrol boats for the entire campaign. Captain Watson warns that the Coho salmon are in imminent danger of extinction and calls for an immediate shutdown of the fishery. The Canadian government declares a salmon fishing moratorium in B.C. but reverses the moratorium after receiving pressure from the fishing industry.

September - October: Captain Watson is put on trial before the Newfoundland Supreme Court on three counts of criminal mischief brought by the government in retaliation for the 1993 cod protection campaign off the Grand Banks. Before a judge and jury, Captain Watson cites the World Charter for Nature as his authority to intervene. The jury accepts the argument, and Captain Watson is acquitted on all the felony mischief charges by reason of color of right. He is convicted of the minor charge of aiding and abetting an act of mischief by crewmember Brad Ryan for throwing stink bombs, who had not been identified or charged. Captain Watson is sentenced to thirty days. He is released after one week pending the appeal.

October: Paul Watson is voted to receive the 1995 Eugene Rogers Award by the United Nations Association of Canada for his work in defense of the salmon in British Columbia.

It is difficult to receive awards when you are actually doing something to deserve one."

By extending this protected area perpendicular from the coast to the boundary all the way to the Atlantic Abyss, a wide diversity of habitats and marine life can be protected.

September: Work begin to prepare the Sirenian for delivery to the Galapagos Islands under the terms of a five-year agreement with the Ecuadorian National Park Service and Navy, responsible for patrolling a 50,000-acre marine reserve but currently only has one boat dedicated to patrols.

The Sirenian is contracted to conduct conservation patrols of the Galapagos Islands Marine Reserve - the first ever to be permitted in the waters of the UNESCO World Heritage Site by a foreign-registered vessel - to clamp down on commercial fishing operations undertaken within 40 miles of the baseline of the biologically unique islands. The Galapagos are a prime target for Asian vessels poaching shark fins and pulling in illegal hauls of the abundant but fragile sea life around the archipelago.

The Varadero I agrees to comply but attempts to flee. The Ocean Warrior deploys fire hoses to force the poacher to comply. The Varadero I accidentally strikes the hull of the Ocean Warrior causing some damage to the poacher and none to the Ocean Warrior. The next morning, the Ocean Warrior is escorting the Varadero I when the Port Captain of San Jose informed Captain Watson that he would be arresting the Ocean Warrior for using force against the Varadero I. The owner of the Costa Rican vessel had bribed the San Jose Port Captain. Captain Watson releases the Varadero I and proceeds on to Costa Rica. When the Ocean Warrior arrives in Costa Rica, Captain Watson is charged with attempted murder and destruction of property based on accusations from the crew of the Varadero I. Captain Watson presents video evidence of the confrontation with the Varadero I to prove that there had been no violence directed at the crew of the poacher and that the Ocean Warrior had been acting on instructions from the Guatemalan government. The charges are dropped and Captain Watson is released. The Ocean Warrior then proceeds to Cocos Island National Park to deliver a donation of a generator, a radar surveillance system, and other equipment to the park rangers. Ten days later the Ocean Warrior returns to the mainland to discover that another prosecutor and another judge have reopened the case after pressure comes from the Costa Rican fishing industry. There are no charges because of insufficient evidence but the court orders that Captain Watson be arrested and held indefinitely without bail until a determination on charges could be made.
