Joining the recent American launch of the RemigoOne e-drive, Temo is introducing its own sleek, clamp-and-ride electric outboard. While similar to the RemigoOne, the Temo 1000 offers a few advantages, including a swappable battery pack.

While hydrofoils lift out of the water thanks to an underwater fin, hydroplanes zoom along by riding directly on the surface of the water. A slick carbon-fiber scale model from startup CovaConcepts shows off the latter concept in a fun new video.

Just last month we trawled the internet for updates to our coverage of the Dynafin propulsion concept from marine giant ABB. Now the technology has been independently tested, which also gives us our first look at the actual system.

Deep sea mining has been off limits because it's awfully hard, and because governments haven't yet firmed up regulations around extracting minerals offshore. That might soon change with The Metal Company's latest move – perhaps sooner than it should.

Gori folding propellers collapse to cut drag when under sail, then open up the instant the motor drive kicks on. The new tri-blade Gori Hybrid Propeller adds a third option, keeping the propeller open while sailing for energy regeneration.

Swiss marine giant ABB has spent more than a decade developing a radically different Voith-Schneider take on a marine propeller. The Dynafin system promises up to 85% efficiency, while giving a vessel super-precise maneuvering capabilities.

Quite similar to the ePropulsion eLite but bigger and more powerful, the RemigoOne is a hassle-free portable electric outboard built for fast, easy transport to and from the water. The push-button e-drive recently made the trip over to the US market.

Honda recently expanded its outboard family around its first-ever production V8. Now, the company is sliding some of the shinier new tech down from the V8 to its V6 and L4 motors, adding handy drive-by-wire tech and boosted efficiency.

Despite having great sea legs, I remember feeling a little green in the gills when faced with strong winds and choppy waters on an island hop a few years back. Would the trip have been smoother in a foiling ferry? A video from Candela has the answer.

eFoiling should be getting a whole lot easier yet also more exciting, according to Lift Foils. The Puerto Rican company has announced its new Lift5 and LiftX boards, which are both quicker to assemble and more capable than their predecessors.

Transporting goods on huge fossil-fueled cargo ships is a dirty business. But one such vessel is about to embark on a pilot that could clean up shipping's act considerably. An onboard system has now been installed on the Clipper Eris that will capture CO2 from its exhaust outlets and store it in tanks.

Whether you're running one of the first commercial foiling e-ferry services or not, it's important for your vessels to be on time. And right on schedule, Vessev's VS-9 has now officially joined the largest ferry operator in New Zealand.

With sights set firmly on supporting the development of hybrid boats, BlueNav has integrated its unique whale-inspired hubless electric drive into a new smart propulsion system with both ICE and electric power.

Augmented reality comes to deep-sea divers, thanks to the US Navy's Office of Naval Research (ONR) and Coda Octopus's Divers Augmented Vision Display (DAVD) system. The setup turns any standard diving hard helmet into a digital information center.

The beauty of an electric surfboard is that you don't need to be pulled behind a speedboat to have fun on the water. Awake's RÄVIK Explore has launched "to open the thrill of electric surfing to everyone – no matter their skill level."
