The Cod Wars, also called the Icelandic Cod Wars (Icelandic language: Þorskastríðin, "the cod war", or Landhelgisstríðin, "the war for the territorial waters"[1]), were a series of confrontations in the 1950s and 1970s between the United Kingdom and Iceland regarding fishing rights in the North Atlantic. In 1972, Iceland unilaterally declared an exclusive economic zone (EEZ) extending beyond its territorial waters, before announcing plans to reduce overfishing. It policed its quota system with the Icelandic Coast Guard, leading to a series of net-cutting incidents with British trawlers that fished the areas. As a result, the Royal Navy deployed warships and tugboats to act as a deterrent against any future harassment of British fishing crews by the Icelandic craft, resulting in direct confrontations between Icelandic patrol vessels and British warships, which included ramming incidents. The dispute ended in 1976 after Iceland threatened to close a major NATO base in retaliation for Britain's deployment of naval vessels within the disputed 200 nautical mile (370 km) limit. The British government conceded, and agreed that after 1 December 1976 British trawlers would not fish within the previously disputed area.[2] At least 15 British frigates were damaged by Icelandic patroal boats by ramming (laughs) That's what you call riots at sea. https://military-history.fandom.com/wiki/Cod_Wars
