The Griffon Hoverwork BHT130 is a medium-size hovercraft, designed by Hoverwork and fitted out in St Helens. The type was found to be unsuitable and was withdrawn after 4 years in service (2007-2011). As a civil passenger hovercraft it seats up to 130 passengers, hence the numerics in its name, the first welded aluminium hull (fabricated by Aluminium Ship Builders, Fishbourne, Isle of Wight) arrived at Hoverwork's St Helens works in August 2005. The first of its kind, named the Solent Express entered cross-Solent service on 14 June 2007; also, in the July of the same year, it was put on trial at a new passenger service between Kirkcaldy and Portobello across the Firth of Forth in Scotland. It remained in service on the Solent until 2011 when it was laid up at Griffon Hoverwork.
