In 1993 the vessel was brought over from Paris to London as part of a £2million investment in the fleet at Catamaran Cruisers,alterations were made including removing the glass enclosed stern and creating an open back deck area among other more mior changes. The vessel was renamed and launched under the new name HYDROSPACE ALPHA.
The vessel boasted features including a sliding glass roof which gave passengers 360 degree views of London (and a sun tan in the summer) , the boat being popular with passengers and crews alike for being able to carry an audience of up to 363 passengers which a member of the crew would give a guided tour to between Westminster to Greenwich. The video below shows a typical guide onboard the vessel.
The vessel continued to operate with Catamaran Cruisers until the company ceased trading in September 2007. Between this time other alterations were made to the vessel which included adding a ladder on the foredeck which allowed easier access to the glass roof for cleaning duties , in 2002 the vessel was re-engined with 2 x Volvo Penta 103A and in 2007 the spotlights along the side decks of both the Alpha & Gamma were removed mainly due to the fact that many were broken and no longer worked.
In early 2008 City Cruises bought the Hydrospace Alpha , Gamma & Delta from Catamaran Cruisers. The Hydrospace Alpha entered service in Feb 2008 however still in Catamaran Cruisers blue and yellow livery with just a city cruises sticker on the windows to show the new owner
By May 2008 the Alpha had returned from drydock in a new smart red, white and blue waterline livery for City Cruises (pictured below)
In 2010 the vessels forward mounted liferafts were removed and additional orange carley floats mounted either side of the wheelhouse, the glass panals either side of the wheelhouse were removed to allow for this
In 2012 the vessel took part in the Queens Diamond Jubilee Pageant
In 2013 after an incident in which the vessel hit a large swell causing the forward windows to break, the vessel had its forward windows removed and the lower section replaced with steel and a smaller glass area above (pictured below) – the City Gamma also had the same modification made at a later date
In November 2015 the City Alpha was slipped at Denton and cut down to deck level to begin its rebuild , the propeller shafts and engines were also removed
