LÉ Deirdre (P20)
LÉ Deirdre (P20) was the first ship purpose-built for the Irish Naval Service. Laid down 10 August, 1971, she commissioned 19 June, 1972. Equipped with a 40mm/60 Bofors gun and a pair of 12.7mm machine guns, Deirdre had a crew of forty-seven, and a top speed of 18 knots. An emphasis of her design was improved sea keeping in the North Atlantic, and this seems to have been rather successful. Deirdre logged 450,000 nautical miles before her decommissioning in 2001. She was sold into civilian use in 2003, and was being converted to a luxury yacht in Poland when her new owner died in 2007. Further refits were conducted in Brazil and Florida, but apparently no buyers were interested and she was scrapped in 2014.
