One of the appeals of paddlesports isn't just being able to look across the water, it's being able to look below its surface. With that in mind, an inventor has made an underwater lamp that lets him observe the seabed while paddleboarding at night.

Pharaohs had round-the-clock guards over their tombs. Today, some of the world’s most vital infrastructure sits on the seabed with far less attention, mostly because adequate tech doesn't exist. Researchers are now developing a permanent subsea guard.

There are a few things more painful than going to the beach on a hard-earned vacation, only to get stung by a jellyfish. The horror! Thankfully, this occurrence may soon be a thing of the past, as researchers have developed an anti-jellyfish buoy.

French upstart Vela Transport hopes to cut shipping emissions by 99% with its marine logistics service. It'll use wind power to propel custom sailboats across the Atlantic Ocean with palletized cargo on board, negating the need for fossil fuels.

Artemis Technologies has launched its latest take on the electric-propelled hydrofoil with its EF-12, which is billed as the world's first 100% electric, zero-emissions hydrofoil pilot boat designed to make transporting ships' pilots greener and safer.

A semi-submersible aquaculture rig that holds more than 14 million gallons of water – 20 Olympic swimming pools' worth – has begun operating in the waters off Hainan Province. It's expected to produce more than 4,000 tonnes of fish in its first year.

One for the "why hasn't this been done before?" department: Norway has greenlit construction of the world's first ocean ship tunnel. If the final budget receives parliamentary approval, work on the Stad Ship Tunnel will begin on the country's west coast.

A floating hydrogen platform that delivers clean power to docked ships – no port construction needed – has passed key engineering tests with early stage deployment talks underway at five major global ports.

If you want to pilot a container ship into Ho Chi Minh city, Vietnam, you'd better be good. Navigating the Long Tau river requires these deep-sea leviathans to turn on a dime, making for some spectacular viewing.

"Ghost ships" may not be able to hide on the high seas much longer thanks to new technology being developed by Mitsubishi Heavy Industries. The system uses a dynamic satellite camera and advanced data processing to visually track ships in real time.

The world's largest sailing cruise ship has a name: the Orient Express Corinthian. The first of the Silenseas class, incorporating a number of high-tech features, has officially been christened at the Joubert graving dock in Saint-Nazaire, France.

Poseidon is probably still getting used to our growth from wooden boats to enormous cruise ships. Imagine his shock when he sees electric boats casually pulling up to recharge right in the middle of the sea, thanks to a new offshore charging system.

"Man overboard!" is one of the most frightening things you can hear aboard ship and the outcome is often tragic. Now, maritime technology firm Zelim has achieved official certification for its ZOE Man-Overboard (MOB) machine-vision detection system.

WRocket is described as the first splittable soft-top surfboard, as it breaks down into three separate sections. Once disassembled, it fits into a relatively compact bag, making it much easier to travel with or store during the off-season.

Sharrow made an efficiency breakthrough the instant it transformed propeller blades into twisted loops, but efficient manufacturing has proven more difficult. It's finally scaling production and slashing build times with 3D sand-casting technology.
