Havengore is a former hydrographic survey launch, originally launched in 1956 for service with the Port of London Authority (PLA). After her withdrawal from service and sale in 1995, she was re-registered as a passenger vessel for up to 40 passengers. Based on the River Thames, Havengore has also served as a ceremonial vessel. She is best known for carrying the body of Sir Winston Churchill as part of his state funeral in 1965.
