Air bags could keep sinking ships afloat

The European Union has invested in a project designed to keep damaged ships stable and afloat by means of airbag-like balloons. It is hoped that the new system, developed under the Su Sy project, will give emergency services extra time to evacuate stricken ships, minimizing the devastating losses of life synonymous with the sinking of cruise ships such as the Costa Concordia, and the South Korean ferry Sewol, which sank earlier this year.

Solo Shuttle Trailer lets you kayak with your bike ... and bike with your kayak

Kayaking down rivers is definitely a fun experience, with new scenery constantly presenting itself at every turn. It does offer one logistical challenge, though – you have to leave one vehicle at your take-out point before you start, then take another vehicle (with your kayak on it) upriver to the put-in. That, or you have to arrange for someone to pick you up. Either way, it's not a one-person activity. Ohio-based inventor Jerry Allen, however, has created a possible solution. His Solo Shuttle Trailer lets you tow your kayak behind your bicycle to get to the put-in, then bring your bike along for the trip to the take-out. Read More

Eco Marine Power unveils solar-electric 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

Using GPS to measure changes in 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.

Sea-Eye monitors the oceans even when tipped upside down

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

BeachRay simplifies the boat into a flat, floating lounge

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

Historically-significant marine chronometer accompanied Darwin

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
