Having already rolled out the world's first ammonia-fueled tractor and the world's first ammonia-fueled semi truck, Brooklyn company Amogy has now got hold of a 1957 tugboat, and plans to have the world's first ammonia-powered ship sailing this year.

If you want decent range out of an electric watercraft, you need to eliminate drag – and that's the thinking behind the WaveFlyer Volaré, launching in Sydney this weekend. Smaller than some jet skis, it hovers over the water for a smooth, quiet ride.

After honing its craft on land, Tarform is looking to drop the fast, exhilarating spirit of its Luna e-motorcycle into the water. The Raye PWC takes on the form of a piece of molten metal poured and cooled into a sleek, slippery vessel with up to 120 hp.

In July last year, Saildrone launched one its sensor-packed unmanned aquatic drones on a voyage of discovery in the North Pacific, tasked with filling in ocean mapping blanks around Alaska's Aleutian Islands as well as off the coast of California.

When conducting cruises in remote areas, eco-conscious guides don't always have the option of charging their electric boat from an existing grid. The Folkloric Explorer eBoat was designed with that fact in mind, as it can be completely solar-charged.

Seasteading proponents envisage a floating society with a fluid geography, free from oppressive government in international waters. But they'll need something to build their watery utopia on top of, and these interlocking seaweed bricks might be it.

In 2020, Evoy presented the world's most powerful electric outboard motor and said even more power was on the way. It makes good on that promise with the all-new Storm 300+, a brawny outboard that does what its name says and spits out over 300 hp.

If you like the idea of flying through the water like a dolphin, then the Seabreacher is the craft for you. However, what if you want to bring more than one friend along? Well, that's where the Jet Shark comes in.
