Answers

Engineers have designed a new spider-shaped vessel that promises low fuel consumption at high speeds. The 100-foot-long water spider is designed for everything from military uses to biological studies, ocean exploration and sea rescue.

Proteus, the so-called Wave Adaptive Modular Vessel costs about 1.5 million dollars. It has a load bearing capacity of 12 tonnes. The craft can travel 5,000 miles – farther than across the Atlantic – on one 2,000 gallon-load of diesel fuel.

Proteus will be able to launch and recover automatic vehicles, do remote vehicle and standard dive support operations. Its makers say that a crew of two can man this large vessel. Unlike conventional boats, Proteus does not push, slap or pierce waves. It utilizes flexibility to adapt its structure and shape to the water surface. Due to the way it is built, Proteus can also manoeuvre directly over small vessels or people to be rescued.
