SS Princess Alice was a Thames river paddle steamer which sank after a collision with the Bywell Castle off Tripcock Point in 1878 with the loss of at least 600 lives. The Princess Alice was first launched in 1865. Originally known as the Bute, she was bought by the London Steamboat Company in 1866. They renamed her the Princess Alice, and put her into service on the Thames excursion route. On September 3, 1878, she was making what was billed as a "Moonlight Trip" to Gravesend and back. This was a routine trip from Swan Pier near London Bridge to Gravesend and Sheerness. Tickets were sold for two shillings. Hundreds of Londoners paid the fare; many were visiting Rosherville Gardens in Gravesend.
