Auckland, 4 April 2005: Sealegs International Limited today announced that it has developed a new all-terrain version of its amphibious marine craft.

The 5.6m Sealegs All Terrain Amphibious Craft (ATAC) has an extremely low ground pressure which is less than a human footprint.

This is achieved by having two special purpose-built 31 inch by 18 inch hydraulically powered wheels on the rear and three steerable tyres at the front. These enable the Sealegs ATAC to traverse estuary mud flats and soft shingle beaches that are beyond the reach of conventional boats and trailers.

Sealegs CEO Mr David McKee Wright says, “We are very excited about the new market possibilities the Sealegs ATAC opens up. People who have waterfront property with soft terrain between them and the water at low tide finally have a boat launching solution for the first time ever”.

Once driven into the water, the Sealegs ATAC hydraulically retracts its wheels to allow speeds of up to 60kpmh on the water. On land the Sealegs ATAC has a ground clearance of 425mm which allows it to climb inclines of over 25 degrees.

Meanwhile, Sealegs Corporation says that plans remain on track for an attempt on the world record for the fastest crossing of the English Channel by an amphibious vehicle later this year.
