With new consumer tech, it's often the case that big corporations will join the party once smaller startups have tested the waters. Such is the case with major manufacturer Sea-Doo, which has just announced its upcoming Rise electric hydrofoil board.

Although one of the big appeals of paddleboards and kayaks is the fact that they are human-powered, there are some scenarios in which a motor could help. The HydroJet was designed with that fact in mind, as it can be mounted on existing watercraft.

Whatever's in the water down in Florida, we want some. As ridiculously awesome as it is awesomely ridiculous, the Shadow Six Typhoon places a UTV body on top of a pair of high-performance jet skis, creating the world's first "aquatic utility vehicle."

Perhaps you like riding your ebike but you also like paddleboarding, and you don't like the idea of having to choose between the two. Well, with the Red Shark Bike you don't need to, as it (sort of) combines both activities in one watercraft.

Researchers from Chalmers University of Technology are working on a new autonomous search and rescue system made up of a marine vessel that can launch a fleet of fixed-wing drones to scout a predefined area, along with live-feed quadcopters.

There are now several different packable boats that can be carried in the back of a car, and assembled onsite. And while most of them fold like origami, the Nanoyacht is a bit different, in that it's made up of multiple nesting boxes.

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.
