Resting 12,500 ft below the surface, the wreck of the Titanic has rarely been visited by manned submarines. But Triton's latest luxury sub can take you down there in air-conditioned comfort, and it sports a clever set of articulating gull wings.

Mercury Marine recently pulled the covers off an all-new flagship, a powerful hunk of water-dipped muscle it bills as the world's first V12 outboard engine. The naturally aspirated 7.6-liter V12 Verado produces 600 hp.

We've already seen electric motorboats and even ferries, but a considerably larger battery-electric vessel should soon be in operation. It's called the e5 tanker and interestingly enough, it will be used to deliver conventional fuel to other ships.

Any unsuspecting swimmers diving off the coast of Cannes may think they've stumbled onto some kind of ancient Easter Island-type civilization swept into the sea, but they'd actually be seeing the work of underwater artist Jason deCaires Taylor.

Back in 2018, Hungary's Narke revealed the world's first electric personal watercraft designed for proper series production – the GT45. Now the company has announced its latest model, with a more powerful electric drive and room for three.

San Francisco-based aquatic drone-maker Saildrone has returned with a bigger and better version of its unmanned vehicle designed to explore the seas, the newly introduced 72-ft (22-m) Saildrone Surveyor.

Italian yacht design firm Lazzarini has unveiled designs for a solar-powered amphibious “crabmaran” that the studio says will be the first in the world. Dubbed Pagurus, the striking 82-ft catamaran merges solar technology and innovative design.

If a boat full of people is zipping across the water, it's possible that one of them could fall overboard without anyone noticing ... at least, not right away. The 1st Mate Marine Safety and Security system is designed to keep that from happening.

While ocean-based fish farms do help take pressure off of wild stocks, they have eco-unfriendly drawbacks of their own. A new underwater robot is being designed to address that situation, by autonomously inspecting the fish and their pens.

No boat catches the eye quite as quickly as a natural-wood boat. Or so we thought. The Castagnola Heritage 9.9 marries its natural wood aesthetic with a glossy black carbon fiber hull shell ... and it catches the eye just as quickly as wood alone.

Although AUVs (autonomous underwater vehicles) excel at gathering marine data without human intervention, they're still limited by battery life. Texas startup Terradepth has set out to address that problem, with a novel tag-team system.

GPS doesn't work underwater, which means that keeping track of a submersible's whereabouts can be difficult. A new ROV (remotely operated vehicle) still manages to show up on Google Maps, however – plus it has a cool rotating head.
