Hoverspeed Great Britain (also known as HIGH SPEED JET, Sea Runner, Speedrunner 1, Emeraude GB, Cosmos Jet, Christopher Columbus)
The 1st of Hoverspeed’s 74m “Seacat” car carrying catamarans was built by International Catamarans (InCat) in Australia was launched as Christopher Columbus on January 28th 1991. Despite being hull number 25, she was launched some months before hull 23 (Seacat France, later Seacat Tasmania). All 5 of these vessels where built to the same “Mark 1” design and specification, with a further 4 built afterwards for other operators to modified specifications. After delivery it was decided to rename Christopher Columbus to Hoverspeed Great Britain. Of the 5 74 metre craft built for Hoverspeed, Hoverspeed Great Britain was the only one to retain the name with which she originally entered service whilst operating for the company.
Hoverspeed Great Britain commenced service on the 14th of August 1990 between Portsmouth and Cherbourg, but was plagued with technical issues being the first of her class in service. On her delivery voyage she had captured the Hales Blue Riband trophy for the fastest crossing of the North Atlantic (Eastbound) which had previously been held by the SS United States for some 38 years.
In November 1990 she made publicity sailings to the Isle of Man and Heysham, before entering service between Dover and Calais/Boulogne. After a final sailing between Portsmouth and Cherbourg on 8th January 1991, she proceeded for refit at Cherbourg. Hoverspeed Great Britain re-entered service on July 20th 1991, a month later than had projected, between Dover and Calais/Boulogne. Between December 1992 and March 1993 she was chartered to Ferrylineas Argentinas S.A. for service between Buenos Aries and Colonia, before returning to the UK to operate between Belfast and Stranraer.
November 1993 saw a return to the Dover to Calais and Boulogne services until March 1994, when Hoverspeed Great Britain operated from Folkestone to Calais. In 1995 she returned back to the Dover to Calais service until March, when she resumed services between Folkestone and Boulogne.
March 2001 would see Hoverspeed Great Britain return back to Belfast, this time operating to Heysham in place of Seacat Denmark which had operated the service the previous year. However, Hoverspeed Great Britain returned again to the Dover to Calais route the following year having been replaced on the Heysham link by the larger Seacat Rapide (by now the Folkestone to Boulogne route had been closed), before layup in 2003.
From 2004 to 2005, Hoverspeed Great Britain was chartered out to French operator Emeraude (renamed Emeraude GB) for services to the Channel Islands. Early 2005 saw a further charter, this time to the Greek operator Aegean Speedlines and a renaming to Speedrunner I. 2008 saw Speedrunner I purchased by Alpha Ferries (also of Greece) who renamed her Sea Runner and used her to operate between Santori and Crete. However, in 2010 the vessel was arrested.
A further Greek operator, Seajets, took over the craft in 2011 and renamed her Cosmos Jet. However, her service between Heraklion, Agios Nilkolaos, and Santori was to last little over a month before Cosmos Jet was laid up in Heraklion with engine problems. She was towed later that month to Keratsini for further layup.
After a career spanning over 2 decades, it has been reported that the former Hoverspeed Great Britain is still laid up in Greece (Chalkis Shipyard, Evia Island) and out of class. Her registered owner changed in June 2015 to Kalan Shipping (another Greek company) according to IHS Maritime, when she was renamed High Speed Jet, however at present we do not know wether she will ever enter service again.
