The Tuxedo Princess (ex-TSS Caledonian Princess) and Tuxedo Royale (ex-TSS Dover) were two former car ferries used as permanently moored floating nightclubs in the United Kingdom from the 1980s to the 2000s. Both ships saw use on the River Tyne at different times, while the Princess also saw use on the River Clyde in Glasgow, and the Royale on the River Tees in Middlesbrough.
The Tuxedo Princess was the first of the two floating nightclubs, moored on the Tyne. When the Tuxedo Princess was briefly moved to Glasgow, the Tuxedo Royale took up her position. When the Tuxedo Princess returned, the Tuxedo Royale was moved to Middlesbrough.
The idea of buying a second-hand ship to serve as a floating nightclub to be moored on the Tyne originated with Tyneside based businessman Michael Quadrini, who already owned the popular Tuxedo Junction nightclub in Newcastle, and several bars, and was looking for a larger venue. And so he purchased the Caledonian Princess, renaming her the Tuxedo Princess. the vessel been built in 1961 as a car ferry, in which role it served until 1981. The later Tuxedo Royale was also a former car ferry, the Dover, built in 1965.
