Finnish engine manufacturer Wärtsilä must be a fascinating place to visit. The company manufactures some of the most mind-bendingly enormous marine diesel engines in the world, like the record-breaking, 89-foot high, 44-foot long, 110,000 horsepower RTA96-C we wrote about more than 10 years ago. Now, Wärtsilä has another entry in the Guinness Book of Records ... for the world's most efficient 4-stroke diesel engine.
Ordinarily, when a ship is heading into waves, those waves cause it to
work harder. An experimental new setup known as a "whale tail," however,
utilizes wave action to actually help ships move forward, allowing them
to use less fuel when tackling rough seas.
While there are plenty of aerial drones that show us our surroundings
from up in the air, there are far fewer remote-control devices that let
us see what's lurking beneath the surface of the water. Although the Aquabotix Hydroview
is one, at around US$3,000 it certainly isn't cheap. While still not
inexpensive, the newest version of the TTRobotix Seawolf is considerably
less pricey – partly because it incorporates the user's existing GoPro
A team from Calvin College, Michigan, is trying to put the "ski" back in "jet ski" with a unique kind of personal watercraft (PWC) that features three skis, a tilting front suspension system and a 650cc engine. Inspired by the dual-ski Wetbike of the 1970s and 80s, and perhaps a little by the bizarre Watercross racing movement, the Jet Blade team has completed prototyping and preliminary water testing.
Not satisfied with creating stylish supercars, Aston Martin is getting its tires wet by teaming up with Quintessence Yachts and naval architects Mulder Design to produce a 37-foot (11-m) powerboat.
Until the 1960s, Japan's three I-400-class subs were the largest submarines ever built. They were so large, in fact, that they could each carry and launch three Aichi M6A Seiran amphibious aircraft. The idea was that the submarines could stealthily bring the planes to within striking distance of US coastal cities, where they could then take off and conduct bombing runs. Now, for the first time since it was scuttled at the end of World War II, one of the sunken subs' aircraft hangars has been photographed.
While stand-up paddleboards are usually a lot of fun to use, they can be a hassle to transport and store. That's why we've seen ones that can be folded up
. The SipaBoard, however, takes yet another approach – it's inflatable. An onboard electric motor pumps the air into it for you, plus it also powers an integrated jet drive that provides paddlers with a boost.
Yachts, often being a plaything of the wealthy, are a fertile breeding ground for flamboyant and luxurious new designs
. One such concept is the 55 m (180 ft) X-Easy motor yacht designed by Monaco-based Pastrovich Studio. The X-Easy is designed for the fun, relaxation and wellness of those on-board.
The all-new Sports Limousine from Tasmania's Van Diemen Luxury Crafts joins the swelling legion of convertible, multi-use boats that includes the sports coupe-styled Revolver 44 GT
and the Kormoran super-transformer
. The Sports Limousine goes a step beyond the basic electric hard-top convertible, adding an electrically raised glasshouse to create three distinct body styles for a myriad of on-water uses. It's a cozy fishing boat, a roomy, semi-enclosed limousine, and a compact tender in one.
