Eco Marine Power has unveiled plans for a solar-electric powered unmanned surface vessel

Eco Marine Power (EMP) has unveiled high level design plans for an unmanned surface vessel (USV) to be powered by a solar-electric hybrid system. The Aquarius USV project began in 2011 and a prototype is expected in 2015. It will mostly be used for data collection and monitoring purposes.  Read More

The Chalmers system uses satnav signals to measure sea level

Measuring sea level is not only an invaluable tool for pilotage, navigation, aeronautics, cartography, sea charting, and geology, it’s also a fundamentally important metric for measuring possible evidence of climate change, and for measuring the direction, extent and rate of such change. Johan Löfgren and Rüdiger Haas of Chalmers University in Sweden have developed a new way of measuring sea level that uses satnav signals for constant, real-time monitoring that promises new insights into many fields, including climate change.  Read More

Bad weather can play havoc with unmanned surface vehicles (USVs) patrolling the seas, which is why scientists at the Universiti Malaysia Perlis (UniMAP) have come up with a USV prototype that works even when it tips over. Called Sea-Eye, the battery-powered vehicle features a design that enables it to work just as well upside down as right way up.  Read More

One of the scientific community's flagship unmanned research submarines, used for deep-sea exploration, has been declared lost as of 2 pm (New Zealand Standard Time), May 10. It was in use by researchers aboard the scientific research vessel, the Thomas G.  Read More

The BeachRay is a boat for minimalists

You don't have to own a Mercedes S-Class to get out on the highway, and you don't need a six-figure speedboat to get out on the water. Lakin Boatworks thinks that all you really need is a flat deck, a couple of lounge chairs and a cooler chilling your drinks and food. That's pretty much the BeachRay in a nutshell, with an outboard motor and simple controls to keep you moving.  Read More

The marine chronometer heading for the auction block on July 9 has certainly witnessed its...

In an age where accurate time measurement is taken for granted, the upcoming auction of an 1825 marine chronometer highlights just how far science has advanced in the last 200 years. The marine chronometer was a critical technology enabling navigation at sea. This 190 year-old example, which is heading for the auction block on July 9, has certainly witnessed its fair share of history in fulfilling that critical scientific role, having accompanied Charles Darwin on his epic five-year second voyage (1831-1836) to South America and the Galapagos Islands, the North American Boundary Expedition (1843-1846) which established the border between the USA and Canada and the 1857 survey of the Australian coastline which saw the naming of Darwin and the Fitzroy River. Given its stellar provenance, the chronometer seems ridiculously cheap if it does fall within its expected price range of … £30,000-50,000.  Read More

With the help of a tow vessel, the Nautboard makes it easier to swim with a dolphin-like m...

No matter how good a swimmer you consider yourself, you'll never have the fluid, natural grace of a dolphin. The Nautboard from Aquanaut International claims to close the gap, allowing you to swoop smoothly up and down underwater like a true creature of the sea. All it takes is a tow vessel and some rope.  Read More

The 2Play's twin hulls are able to move up and down relative to the deck

Water may seem soft enough when you're in a bathtub full of the stuff, but as anyone who has smacked across the waves in a speeding motorboat knows, it can also be relatively hard and unyielding. With that in mind, one has to wonder ... why don't we hear more about suspension systems for watercraft? Well, if the folks at Australia's Nauti-Craft have anything to say about it, we soon will. Their prototype 2Play catamaran incorporates an interlinked hydraulic suspension, that isolates the deck from the two hulls.  Read More

Sweden's Movitz ferry, the first 'supercharged' electric passenger ferry, debuts in August...

Sweden’s Green City Ferries is preparing to launch what it claims is the world’s first “supercharged” electric passenger ferry. Carrying 100 passengers between Solna Strand and Gamla Stan, the Movitz will need just 10 minutes to charge its batteries between 1-hour long service runs. That’s perfect for a ferry operation, because it means it’ll be charged by the time passengers have embarked and disembarked. With extremely low maintenance requirements and reduced running costs, the ferry will reportedly save some 50,000 litres of diesel and 130 tons of carbon emissions into the bargain.  Read More
