The "world’s first serial-production electric hydrofoil ferry" – the Candela P-12 – has completed a record-breaking voyage from Gothenburg in Sweden to Oslo in Norway, clocking up 160 nautical miles over the epic three-day journey.

Nuclear power isn't just for naval ships anymore as demonstrated by the Nuclear Propulsion in merchant Shipping (NuProShip II) project led by the Norwegian University of Science and Technology which is looking at fitting nuclear reactors to heavy-duty commercial vessels.

The world’s largest battery-electric ship has quietly begun harbor trials on the River Derwent in Hobart. Built by Incat Tasmania, the Hull 096 represents a major step forward for large-scale electric shipping.

Sometimes safety becomes unsafe when it's carried too far. A new study by Lloyds Register reveals that ships, especially cruise ships, have so many alarms going off on the bridge that it's overwhelming crews and creating unsafe conditions.

By lifting its hull above the water on a hydrofoil, Awake’s new NAVI electric foiler does away with spray and noise with a smooth, efficient glide. It’s not for everyone, but it shows how refined and practical electric foiling has become.

Texas A&M’s Ship collision avoidance of Machine learning And Radar Technology for Stationary Entities and Avoidance (SMART-SEA) system combines AI, radar, and human expertise to help crews navigate one of the most complex safety problems at sea.

In the South China Sea, the aqua-colored waters of an expansive shallow reef platform suddenly gives way to a near vertical shaft of vast darkness – an ocean sinkhole almost entirely devoid of oxygen and, in turn, marine life as we know it.

British cyclist Paul Spencer plans on breaking records and raising funds by pedaling his way around the world. He'll use a bike on the land, and a very unique pedal-powered trimaran on the water.

A team of Australian bodyboarding ratbags has managed to capture staggering footage of an extraordinary oceanic phenomenon: a place where four 12-ft (3.7-m) waves regularly converge into an oval dip, with explosive results.

Although underwater scooters may offer users an aquatic "thrill ride," many of the things don't go much faster than the person could swim on their own. Such is not the case with the Sublue Vapor, however, which tops out at a speed of 10 km/h (6 mph).

Helix builds some of the most power-dense electric motors in the world. Now it's working to springboard that compact, power-packed design into a marine pod drive ecosystem it believes will help change the face of everyday boating.

Blurring the line between biology and robotics, Chinese scientists are taking biomimicry to new depths with a small, low-energy bionic jellyfish that's so lifelike in form and movement it’s almost indistinguishable from the real thing.

A year ago, Sharrow launched the MX-A propeller for small outboards, effectively cutting pricing by more than half compared to previous prop launches. Now it's doing it again with the AX, a sub-$1K propeller designed for even smaller outboards.

Electric powersports marque Taiga gets more ambitious with a larger, more versatile electric adventure PWC that seats up to three people. Despite the extra size, the new Orca WX3 still promises hours' of time on the water per 30-min charge.

Lamborghini has teamed with e-PWC specialist Cayago to develop what it calls the "most powerful Seabob ever," a grab-and-go personal jet sled that promises exhilaration on and under the water at speeds that compete with various species of shark.
