August 24, 2005: New Zealand-based Sealegs has unveiled an all-new aluminium amphibious craft. The 5.6m amphibious D-Tube features a 4mm marine grade aluminium hull with 3mm aluminium D-Tube shaped pontoons. An inboard air-cooled 16hp Honda engine powers hydraulic wheels motors, allowing the D-Tube to drive at up 10kmph on land and 60kmph on the water. Once in the water, a button is pushed to hydraulically retract the wheels and the Sealegs D-Tube becomes a normal sea-going boat. The boat is based on the boat which halved Sir Richard Branson's English Channel record in June. The standard SeaLegs boat cut the previous record of one hour, forty minutes and six seconds to 43 minutes and 12 seconds ( see pics inside of record). Gizmag has covered a wide range of amphibious vehicles in recent times, including the original launch of Sealegs, the Gibbs Aquada Sportcar, the Gibbs Humdinga 4WD amphibian, the Platypus 4WD amphibian, the Rinspeed Splash, the Phibicat and the Amphicar.
