Seahorse incorporates your bike into a human-powered airboat

By - December 1, 2014 4 Pictures
Back in the early 90s, MIT's Prof. Mark Drela created a motor-less hydrofoil known as the Decavitator. Using nothing but his own leg power to turn the craft's 10-foot (3-m) air propeller, he got it up to a speed of 18.5 knots (21 mph/34 km/h), breaking the human-powered water speed record in the process. Inspired by the Decavitator, aerospace inventor Russell Randall created his own pedal-propelled airboat called the Seahorse – and you can now buy one of your own. Read More

Review: Sea-Doo Spark, the jet ski that might save the industry

By - November 19, 2014 37 Pictures
The PWC market has been in decline for a number of years, possibly because jet skis have become so gigantic, powerful, expensive and fuel hungry that they've stopped appealing to younger folk. Sea-Doo is starting to turn that around, though, with the release of the Spark. Half the price, half the weight and half the power of a regular midrange jet ski, the Spark delivers 90 percent of the fun of a more expensive PWC in a way that's much more accessible and attractive to newcomers … and burns nearly ten times less fuel than the big boys. If it's newbies the Spark is hoping to attract, then we've got a total newbie on the team to test it. The completely inexperienced Loz Blain and the moderately experienced Noel McKeegan take to the water to see how she goes. Rejoice, dear readers, that Loz didn't fit into a wetsuit, and is thus not depicted in skin tight clothing. Read More

Flash Catamarans puts a two-story luxury apartment on two hulls

In designing the new Flash Cat 67SC, Spain's Flash Catamarans has attempted to redefine the shape and packaging of the large, dual-hulled vessel. To do so, it's lifted the cabin space out from its stuffy confines below deck, offering an open, airy interior with big picture-window views out to sea. The wide, above-deck design also provides better accessibility for disabled passengers. Read More

Ocean gliding robots used to study melting Antarctic sheet ice

By - November 17, 2014 2 Pictures
The use of "ocean gliders" for conducting research in oceanic conditions not ideal for regular methods has been catching on in the scientific community. Examples of this have been seen in the detection of endangered whales in the North Atlantic and a study of the Atlantic sturgeon. Researchers have now turned their robotic ocean helpers towards Antarctica, to study the rapidly-melting ice sheets on the coast of the western part of that polar land mass. Read More
