In 1892 the French built the first all-aluminium seagoing vessel, a 40-foot yacht and now, more than 100 years later, aluminium is still a favourite material for yacht spars, fittings and hulls.

By 1893, an American company was making aluminium rowboats. Aluminium marine alloys were developed and today about 50 per cent of outboard motors are made of aluminium.

Passenger liners also use aluminium with large ones containing as much as 2,000 tonnes of aluminium. This allows for a considerable weight reduction – hence far greater fuel efficiency - when compared with their steel counterparts.

Fast ferries, with speeds of 35-50 knots, are revolutionising transport over short sea routes. These structures are weight-critical, and aluminium is the preferred material. A modern ferry can use up to 400 tonnes of aluminium.

Users report that aluminium craft have been in service for over 30 years with no signs of metal fatigue. Low maintenance is also a significant feature of aluminium vessels.
