Suspension-packing 2Play catamaran smooths out rough seas

Water may seem soft enough when you're in a bathtub full of the stuff, but as anyone who has smacked across the waves in a speeding motorboat knows, it can also be relatively hard and unyielding. With that in mind, one has to wonder ... why don't we hear more about suspension systems for watercraft? Well, if the folks at Australia's Nauti-Craft have anything to say about it, we soon will. Their prototype 2Play catamaran incorporates an interlinked hydraulic suspension, that isolates the deck from the two hulls. Read More

Riverwatch uses robotic symbiosis to study waterways

The string of disastrous floods currently plaguing Britain demonstrate that managing rivers and other waterways is about more than protecting curlew nests and counting otters. To help provide a better understanding of riverine areas, a team headed by José Barata and Pedro Santana of the University of Lisbon are developing a “marsupial” robotic system called Riverwatch that teams a robotic catamaran with an on-board hexacopter to survey areas beyond the reach of the hip-boots and rubber raft brigade.Read More

The Platypus: Underwater vehicle creator thinks outside the bubble

Vehicles such as the EGO semi-submarine boat and Adventure-Doo are designed to bring the underwater action within reach of those without the time or inclination to put in the training required to get behind the controls of personal submarines like the offerings from U-boat Worx. But the Platypus underwater exploration vehicle from François-Alexandre Bertrand ditches the waterproof hull while giving users a taste of life beneath the waves. We first looked at the Platypus in concept form in 2011 and a prototype has now hit the water as it navigates the often-treacherous waters to commercial availability. Read More

Sunreef 80 Carbon Line superyacht hits the water

Sunreef Yachts’ first luxury catamaran in its new Carbon Line hit the open water for the first time last month and is undergoing sea trials before making its way to the Cannes Boat Show 2013 in mid-September for its world premiere. To reach its lightship weight (the weight of the completed vessel, minus any provisions, supplies or cargo) of 45 tonnes (49 tons), the 80 Levante is made from an advanced composite sandwich that combines vinylester, PVC foam and carbon/glass fiber.Read More

World's largest solar-powered boat returns to the oceans in the name of science

The MS Tûranor PlanetSolar, the world's largest solar-powered boat, took to the seas once more on Thursday – this time, in the name of science. Equipped with unique instruments, the Tûranor will carry a team of scientists who will monitor the air and water of the Atlantic Ocean's Gulf Stream, a current which influences the climates of North America's east coast and Europe's west. The goal is to gain understanding of the processes which regulate climate.Read More
