Editing Hovercraft (section)

====Hoverbarge====
A real benefit of air cushion vehicles in moving heavy loads over difficult terrain, such as swamps, was overlooked by the excitement of the British Government funding to develop high-speed hovercraft. It was not until the early 1970s that the technology was used for moving a modular marine barge with a dragline on board for use over soft reclaimed land.

Mackace (Mackley Air Cushion Equipment), now known as Hovertrans, produced a number of successful Hoverbarges, such as the 250&nbsp;ton payload "Sea Pearl", which operated in Abu Dhabi, and the twin 160&nbsp;ton payload "Yukon Princesses", which ferried trucks across the Yukon River to aid the pipeline build. Hoverbarges are still in operation today. In 2006, Hovertrans (formed by the original managers of Mackace) launched a 330-ton payload drilling barge in the swamps of Suriname.<ref>{{Cite web|date=2010-08-25|title=Hover barge History

The Hoverbarge technology is somewhat different from high-speed hovercraft, which has traditionally been constructed using aircraft technology. The initial concept of the air cushion barge has always been to provide a low-tech amphibious solution for accessing construction sites using typical equipment found in this area, such as diesel engines, ventilating fans, winches and marine equipment. The load to move a 200&nbsp;ton<!-- Which ton? --> payload ACV barge at {{convert|5|kn|km/h|abbr=on}} would only be 5&nbsp;tons. The skirt and air distribution design on high-speed craft again is more complex, as they have to cope with the air cushion being washed out by a wave and wave impact. The slow speed and large mono chamber of the hover barge actually helps reduce the effect of wave action, giving a very smooth ride.
