Last year, Swedish electric boat maker Candela announced plans to launch a foiling passenger ferry called the P-30. Now in the final design phase, the craft has been renamed the P-12 Shuttle and will hit the water as a foiling catamaran.

Norway's Argeo has launched the first uncrewed survey and inspection vessel based on the Mariner X platform from Maritime Robotics. The Argus is expected to undertake mapping and inspection operations for offshore wind projects.

Although pedal-powered boats do exist, most use either a propeller or flapping fins. Ben Kilner's one-off Jamima Paddleduck takes a different approach, with two rear paddles mounted on a bike frame – and the setup has some definite selling points.

Artemis Technologies has launched what is claimed to be the world's first commercially viable all-electric foiling workboat, which cuts through the water at up to 34 knots and offers a per-charge cruising range of up to 60 nautical miles.

Following a number of technical setbacks, the Mayflower autonomous research vessel has successfully crossed the Atlantic Ocean, clocking up 3,500 miles and arriving in Halifax, Nova Scotia, on June 5.

Zaha Hadid Architects has turned its design expertise to the exclusive world of luxury yachts, with a new catamaran named the Oneiric. It's hailed as Italian shipbuilder Rossinavi's green technology flagship, and could run fully from solar power.

It would cost a lot of money to send a boatload of marine scientists across the Atlantic Ocean, all of them conducting research along the way. That's where the Oceanus will come in, as plans call for it to do the job without any crew aboard.

It was just this February that we heard about the first "flight" of Candela's C-8 electric hydrofoil. Now, the Swedish company has announced its latest model, the better-appointed P-8 Voyager.

China christened a remarkable new 290-foot (88-m) ship last week – the world's first semi-autonomous drone carrier. It'll carry, launch, recover and co-ordinate the actions of more than 50 other autonomous aerial, surface and underwater vehicles.

California's Marine Advanced Robotics has made considerable progress on its remarkable Wave-Adaptive Modular Vessel since we first saw these wild suspension-legged spider-boats 16 years ago on a list of urban legends.

Several groups in Japan have been demonstrating fully autonomous ships in the last few months, and the latest, a 95-m container ship, has just completed a 790-km autonomous voyage starting and ending in the heavily congested waters of Tokyo Bay.

If you've ever gone out on a booze cruise and thought "gee, I wish there was less fresh air," this one's for you! Dutch submarine company U-Boat Worx has announced an enormous new underwater venue for up to 120 guests plus a full crew and staff.

Norway-based marine group Ulstein has introduced Thor, its concept design for a 149-m (489-ft) replenishment, research and rescue (3R) ship powered by a thorium Molten Salt Reactor (MSR) that can be used to recharge battery-driven cruise ships at sea.

Italian senior yacht designer Luca Bassani is the force behind the world’s first full-wide-body superyacht. Dubbed wallywhy200, it's a modern vessel that boasts innovation, space, speed and performance.

Italian startup iSpace2o has announced it's starting production on the first hull for its Deepseaker DS1 submersible hydrofoil. This machine will rise out of the water to hydrofoil at up to 23 knots, or dive as deep as 50 m for underwater shenanigans.
