University of Texas team takes control of a yacht by spoofing its GPS

Civilization depends on the Global Positioning System for everything from precision armaments to finding the location of the nearest pizza shop. Indeed, access to GPS's strengths and capabilities has grown so fast that little concern about its weaknesses has penetrated the public consciousness. Fortunately, assistant professor Todd Humphreys' team at the University of Texas at Austin continues to arrange splashy demonstrations of GPS spoofing. His latest is to covertly alter the course of an oceangoing yacht.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.

Office of Naval Research uses UAVs to study radio propagation

Radio has come a long way since Marconi bashed a telegraph key and radar is a miracle compared to when it was just a squiggle on a cathode tube, but despite a century of advances, they’re still prone to the same problems as the first pioneers encountered. For five days in July, the Office of Naval Research’s (ONR) Research Vessel (R/V) Knorr made a survey in the waters off Virginia Beach, Virginia using ScanEagle UAVs to study the effect of oceanic and atmospheric changes on radar and radio waves with the aim of producing more secure military communications and improve the ability of radar to detect hostile craft.Read More

Volkswagen's caged Beetle Convertible swims with the sharks

A convertible shark cage may be a complete oxymoron, but Volkswagen and partners have built one for Discovery Channel's upcoming Shark Week. More than just a stationary exhibit, the shark cage is a functioning watercraft with impressive capabilities. Gizmag talked to Luke Tipple, the marine biologist, shark diving expert and TV personality responsible for building and driving the craft, to find out more about what it's like to scooter around shark-infested waters in a skeletal Beetle ragtop.

James Bond’s submersible Lotus Esprit going under the hammer

While the pursuit to develop flying cars and Star Warsian land-speeders rages on, the dilemma around developing a functioning underwater vehicle was solved decades ago … by the British Secret Service's Q Branch. In the film The Spy Who Loved Me, James Bond escapes from the obligatory horde of bad guys by driving one very versatile white Lotus Esprit into the ocean. That fully submersible vehicle, is now set to go to auction this September. Read More

Is it a Jeep? Is it a speedboat? No, it's WaterCar's Panther amphibious vehicle

Recreational amphibious vehicles are nothing new, but most are one-offs, and most tend to be boats that can creep on land, or cars that slosh slowly through water. There are exceptions, notably entries from Gibbs, but arguably, amphibious vehicles have not made the grade as true all-round vehicles that can be driven to work during the week, and on the lake on weekends. WaterCar's new Panther straddles the divide. Read More

Upgraded Alvin submersible sets sail

You would think that a little sub built almost 50 years ago would be sitting in a museum somewhere, but Deep Submergence Vehicle (DSV) Alvin, which launched in 1964, is still going strong. Owned by the US Navy and operated by the Woods Hole Oceanographic Institution (WHOI), Alvin has completed a major US$41 million redesign and refit. The revamped submersible set sail on Saturday aboard its mothership R/V Atlantis for certification testing off the coast of Oregon and California.Read More

Europe joins race to store energy at the bottom of the ocean

"Imagine opening a hatch in a submarine under water. The water will flow into the submarine with enormous force. It is precisely this energy potential we want to utilize." This is how German engineer Rainer Schramm describes his idea for storing energy under the sea. By using surplus energy to pump water out of a tank at the seabed, the water is simply let back in again when there's an energy shortfall, driving turbines as it rushes in. The deeper the tank, the more power is generated.Read More

The good news is that, if the campaign proves successful, supporters should be able to enjoy their boards this year, and for as little as $2,500.Read More
