In 1981 the Royal Belgian Marine (RMT) introduced two jetfoils, the 'Prinses Clementine' and the 'Prinses Stephanie', on the Dover to Ostend service. The Boeing jetfoils reduced the crossing time between England and Belgium to 100 minutes, as opposed to about four hours by ship. In 1993 the jetfoils left Dover and started operating from Ramsgate to Ostend and were finally withdrawn in 1997.
Hoverspeed started operating fast catamarans, known as seacats from Dover in July 1991. The craft initially operated from the Eastern Docks until June 1993, when a special berth was constructed for them alongside the Prince of Wales Pier at the Hoverport. In late 1993 the Dover based seacats were withdrawn and transferred to the Folkestone - Boulogne route but returned to the Dover to Calais service the following summer. In March 1998 seacat services between Dover and Ostend were introduced.In October 2000 Hoverspeed withdrew its ageing hovercraft, replacing them on the Dover to Calais route with seacats. The hoverport terminal building remained in use for seacat passengers. In late 2002 Hoverspeed announced that the summer only service to Ostend would not be reintroduced for the Summer 2003 timetables. The Dover to Calais route closed on 7 November 2005, the Seacat ‘Diamant’ operating the last crossing.
