Westminster Passenger Services Association (regularly advertised as Thames River Boats)[https://www.thamesriverboats.co.uk/index.asp Thames River Boats Website] is a provider of regularly scheduled boat services on the River Thames in London. It is licensed by London River Services to run daily services from Westminster Pier to Kew Pier, with longer cruises also available which continue upriver to Richmond landing stage and Hampton Court landing stage.[https://www.thamesriverboats.co.uk/thames-boats/latest-sailings.asp Thames River Boats Latest Sailings] The cruises from Westminster Pier to Hampton Court are the longest regularly scheduled river services in London. Thames River Boats also operate 45-minute circular cruises from Richmond which usually take place on-board M.V. Princess Freda, a Dunkirk Little Ship which assisted with Operation Dynamo.[https://www.thamesriverboats.co.uk/boats/index.asp?page=princess-freda-105 M.V Princess Freda on the Thames River Boats website][https://www.adls.org.uk/princess-freda M.V Princess Freda on the Association of Dunkirk Little Ships website]
It takes approximately 90 minutes to travel between Westminster and Kew, between two hours and two hours 20 minutes from Westminster to Richmond, and between three hours 30 minutes and four hours to travel between Westminster and Hampton Court. As with many river services, travel times are affected by the state of tide. Cruises between Kew and Richmond navigate through the half-tidal Richmond Lock and cruises between Richmond and Hampton Court navigate through Teddington Lock.
In 2021, the following boats are available for the service: M.V. Clifton Castle, M.V. Connaught, M.V. Queen Elizabeth and M.V. Princess Freda (all owned and operated by Colliers Launches), and M.V Cockney Sparrow (owned and operated by Maynard Launches).[https://www.thamesriverboats.co.uk/index.asp Fleet Information on the Thames River Boats website][http://www.collierslaunches.co.uk Colliers Launches Website][https://www.cockneysparrow.co.uk/ Cockney Sparrow Website]
