Trinity House Vessel (THV) Patricia is the Trinity House flagship, one of the fleet of lighthouse tenders that maintain and service maritime navigation aids primarily in English and Welsh waters.
Built by Robb Caledon in Leith in 1982, her work includes refuelling offshore lights, maintenance, towing, buoy work, and wreck location and marking.
Patricia is fitted with towing winches, which provide a routine capability for moving lightvessels to and from their stations. She also has a 20-tonne speed crane capable of lifting the largest navigational buoys and a helideck aft.

The current Patricia is the third with that name. In 1994 she led the Royal Yacht Britannia at the D-Day 50th Anniversary Fleet Review. She is fitted with additional accommodation for the annual inspection voyages by the Trinity House Elder Brethren.

Patricia works alongside the Trinity House Vessels THV Galatea and THV Alert.
