HMS Tiger Bay HMS " Tiger Bay " was a Z - 28 class patrol boat operated by the British Royal Navy , previously the Argentine Coast Guard vessel PNA " Islas Malvinas " ( GC - 82 ) , which was seized at Port Stanley by the crew of on 14 June 1982 following the Argentine surrender during the Falklands War . Service history . " Islas Malvinas " was one of 20 vessels of the class built for Argentina by Blohm + Voss of Hamburg , Germany , all of which entered service in 1978 . Following the invasion of the Falkland Islands on 2 April 1982 , " Islas Malvinas " and her sister ship " Rio Iguazú " ( GC - 83 ) , sailed from Puerto Nuevo , Buenos Aires , on 6 April , with stops to take on fuel and supplies at Puerto Madryn and Puerto Deseado . The two ships then sailed the to Port Stanley , arriving on the 13th . The next day they were repainted from white to brown and green camouflage colours . " Islas Malvinas " was employed in various tasks , including reconnaissance patrols , radar sweeps , search and rescue missions , and piloting vessels entering Stanley Harbour . She also acted as an escort to supply ships sailing to remote military outposts . On 30 April she developed a fault on one propeller shaft , which cut her speed by half , but continued to operate . On 1 May , while escorting the supply ship ARA " Forrest " off Kidney Island , she engaged a British Lynx HAS . 2 helicopter from the frigate . One crewman , Corporal Antonio Grigolato , was wounded by shrapnel before the helicopter retired , having been damaged by machine gun fire from " Forrest " , receiving hits in the engine , fuselage , fuel tank , tail rotor and cockpit . On 14 June , following the cessation of hostilities , she was manned by crew from various Royal Navy Ships , and operated as HMS " Tiger Bay " , named after the Tiger Bay area of Cardiff . She originally had a ' tripod mast ' which she lost whilst transporting wounded to the Hospital Ship " Uganda " in moderate swells . " Uganda " ' s ' fat round bottom ' rose up and sat on top of the upper - structure crushing down the mast . The mast was not replaced . She acted as a ' courier ' for those ashore by ferrying from supply ships at anchor essential needs to landborne service men stationed at various parts of the islands . The RN crew had not been long onboard when they found that the ' leaving ' Argentine crew had left a welcoming present , mainly in the aft deck ammo locker , nicely booby - trapped with explosives . Information came to hand that the Argentine engineer had organised this prior to being taken off the vessel . He was , much to his dislike , obtained and brought back to the vessel to disarm the ' bomb ' . Even though hostilities had ended , " Tiger Bay " and its RN crew came under fire on a few occasions whilst underway around the Falklands , from Argentines ( who had yet to be rounded - up ) and by overzealous British squaddies who were not aware that she was now manned by British naval personnel . She was eventually transported to HMNB Portsmouth , and was eventually sold in June 1986 . A name board from " Islas Malvinas " , which had been presented to Royal Marine Colonel Ian Baxter , was sold at auction in 2009 for more than £5 , 000 , ten times its estimated value .
