LÉ Deirdre (P20)
LÉ "Deirdre" (P20) was a ship in the Irish Naval Service. She was named after Deirdre, a tragic heroine from Irish mythology who committed suicide after her lover's murder. Built in 1972, "Deirdre" was built as a replacement for the s, and one of the first vessels custom-built for the Irish Naval Service. She was to have longer range and be a more seaworthy ship for work in the Atlantic. "Deirdre" became the prototype for the later -type vessels. "Deirdre" undertook a number of search and rescue operations throughout her careers. For example, "Deirdre" was  one of the vessels involved in the 1979 Fastnet race rescue operations, assisting the crews of two yachts. In 1990, during the rescue of a Spanish trawler crew in Bantry Bay, a member of "Deirdre"<nowiki>'</nowiki>s crew died – and was posthumously awarded the Distinguished Service Medal and Spanish Cross of Naval Merit. By the time of the vessel's naval decommissioning in early 2001, "Deirdre" had travelled approximately 450,000 nautical miles. She was replaced by a Róisín-class patrol vessel. "Deirdre" was sold at public auction for IR£190,000 in . She was purchased by the English yacht chartering company Seastream  International for conversion into luxury charter yacht "Tosca IV" for the company's owner, businessman Christopher Matthews. Speaking on the radio, a Seastream spokesman appeared pleased with their bargain as they had been prepared to bid up to IR£500,000. The auction starting price had been IR£60,000. The conversion in a Polish shipyard was not completed as the English owner died. In 2007 she was towed to Brazil for further refit and completion. Substantially complete, she arrived at Jacksonville, Florida in September 2012 for final outfitting as "Santa Rita I". However, in August 2014, "Santa Rita I" was towed to Green  Cove Springs, Florida, for breaking.
