The HSC Cat is a high speed catamaran ferry built by Incat for Sea Containers in 1990.

The vessel's first spell in service was on charter to Tasmanian Ferry Services and was deployed on the route across Bass Strait between Port Welshpool and George Town until 1992 when the vessel moved to England operating across the English Channel between Dover and Calais and also Folkestone and Boulogne-sur-Mer for Hoverspeed.

Emeraude France spent six months on charter to the Isle of Man Steam Packet Company and provided a reliable service during the Centenary of the Isle of Man TT in 2007 operating mainly on the Douglas to Dublin and Belfast routes and occasionally serving Liverpool and Heysham.

In September 2007 the vessel's charter ended and Emeraude France moved to Tilbury for lay up until it was acquired by Sea and Sun Maritime Co in May 2014 and renamed Superfast Cat.
