After almost half a century in service, the revamped Alvin submersible is once again headi...

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

By exploiting pressure at the seabed, researchers hope to create stores of energy at the o...

"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

Hyundai Heavy Industries tests out its new miniature robotic welding arm

Hyundai Heavy Industries (HHI), which lays claim to being the largest shipbuilding company in the world, says it has developed a miniature welding robot that can be easily transported by a worker and affixed to a ship using magnets. The small, portable robot is expected to increase worker productivity two to threefold.  Read More

The Kymera electric powered body board can be yours for as little as $2,500

When we last checked in with Jason Woods, he’d electrified his Kymera powered body board and was aiming for a 2013 release and US$5,000 retail price. To finally get the Kymera in the hands – or under the bodies – of consumers, Woods has now decided to go the crowdfunding route. 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

'Why five engines? Simple, because six wouldn't fit,' says Skip Brewer, CEO of Cigarette R...

Cigarette Racing and AMG have collaborated on the newest version of the Huntress performance boat, which was officially unveiled this week at the Miami International Boat Show. A little more roomy than classic go-fast boats, the 42-foot Huntress is ten feet high, has an 11-foot, 9-inch beam and a cabin below decks providing luxury accommodation for two. Oh, yes – it also comes with a 500 gallon fuel tank and five Mercury Racing outboards that can push it up to 78 mph (125 km/h or 68 knots).  Read More

Chief scientist Mark Baumgartner secures a glider (with its wings removed) after it was re...

Every year between November and January, endangered North Atlantic right whales are thought to use an area off the coast of Maine known as the Outer Fall as a breeding ground. They are “thought to” because the ocean conditions at that time of year can make it difficult to locate them. Two autonomous marine robots called gliders have now been used as a real time whale-detection system for researchers and to warn boats in the area to slow down to avoid striking the marine mammals.  Read More

The Azimut Grande 140 Trideck

Azimut Yachts, the Italian shipyard noted for luxury yachts, revealed its Azimut Grande 140 Trideck with a new Rolls Royce propulsion system at the 2012 Cannes Boat Show in September. With an overall length of 42 meters (138 ft) and displacement of 276 tons (280.4 tonnes), this is the largest Azimut Grande model ever built and is the first vessel to feature the Rolls Royce Carbon Azipull 65C propulsion system with fully steerable pods.  Read More

The Aquarius Eco Ship concept based on the EnergySail technology that uses solar panels em...

In the 400 years or so leading up to the adoption of steam power in the 19th century, sailing ships ruled the waves. In an effort to cut increasing fuel costs and reduce emissions, sails are set to once again prove their worth. But unlike the sails proposed by B9 Shipping and the Wind Challenger Project, Japan-based Eco Marine Power (EMP) is developing sails with an even more modern twist. Rather than just harnessing the power of the wind, EMP’s EnergySail can be fitted with solar panels to also harness solar power.  Read More

The auto world's attention is currently turned to the dryness of the desert thanks to the 2012 SEMA Show going on in Las Vegas. At least one automaker is making a splash in the water, however. Jaguar has followed the lead of Mercedes-Benz in introducing a boat concept.  Read More

The Kymera powered body board can reach speeds of up to 25 mph (40 km/h)

It’s been over 20 months since we last looked at the Kymera jet-powered body board and it’s great to see that its creator, Jason Woods, has stuck with his dream of developing a compact and lightweight personal watercraft. In the time since our last story, Woods has continued to plug away in his garage refining the Kymera, which now sports a new hourglass shape, has made the switch from gasoline to electric power, and has attracted the interest of search and rescue (SAR) teams. Most importantly, the Kymera is nearing commercial availability, with Woods aiming for a release in 2013.  Read More
