Sir Winston Churchill was a sail training ship which was built in Hessle, Yorkshire by Richard Dunston Ltd. She was sold out of service in 2000 and currently serves as a private yacht.

Public donations partly funded construction of the ship,[2] and the Sail Training Association raised about half the needed money.

[4] On January 1, 1967, an open porthole near the waterline allowed the rising tide to flood the ship at her berth in Southampton, Hampshire.

[3] On 27 July 1981, she ran aground 4 nautical miles (7.4 km) off Great Yarmouth, Norfolk with 39 female trainees on board.

[8] In 2000, Sir Winston Churchill was replaced in service by Prince William and sold by her owners, the Tall Ships Youth Trust.
