Sealegs charges into the future with amphibious craft on renewable energy

Sealegs is a world leaders in amphibious crafts, designed and developed to take all the hassle out of boat launching and retrieval. The system simply drives from a storage location, down a boat ramp or beach and into the water. Once afloat, the wheels lift up out of the water to be stored against the hull, and the boat is used as normal.

The company has been driving the amphibious boating revolution since its start in 2001. The very first versions had electric motors driving the wheels, while across the rest of its models hydraulic propulsion is powered by a petrol engine. But the E4 combines high-torque brushless electric motors with MG’s high density 7kWh lithium battery technology. In many ways it may be the best Sealegs craft yet.

Without a petrol engine roaring the E4 is quieter, but runs faster and longer than conventional models. With a standard 150hp outboard it achieves 40 knots, while it drives for around 1.5 hours on a land, depending on speed, load and terrain. Performance is further increased by regenerative braking and outboard charging. All the usual safety features, such as emergency braking, are included.

Without having to accommodate a petrol engine, there’s more flexibility to house the 51 V 7 kWh lithium ion battery, which takes four to five hours to fully recharge, by simply plugging it into a 240 V mains supply. The outboard also feeds the battery via the VSR and a PowrFlow step-up charger, as does the regenerative braking system. Solar power is another option. All systems are connected to a central Naviop display which supports MG’s battery systems to show battery status.

Combining of the latest battery and motor technology quite possibly represents the future of amphibious boating. “The release of the Electric E4 takes Sealegs’ global leadership position in amphibious technology to the next level,” according to Founder and Chief Technology Officer Maurice Bryham. “We have made our amphibious system 33% faster, 60% quieter and 50% more powerful.”

Loodswezen saves weight by replacing lead acid battery banks by MG’s High Power alternative

Loodswezen‘s maritime pilots make sure sea-going ships enter and exit their ports as safely and efficiently as possible. Day and night. Under any circumstance. The highly trained crew assists over 90 000 vessels a year in their voyage to and from Dutch and Flemish seaports on the Scheldt River and is on call 24 hours a day.

Tenders are used for embarkation and disembarkation as well as transporting the pilots smoothly and securely. Normally these very manoeuvrable boats come equipped with large and heavy lead-acid battery banks in order to deliver energy for propulsion and onboard service systems.

However, in close cooperation with MG a unique and innovative systems has been installed, consisting of 4 compact, light yet highly powerful battery modules, strong enough to deliver the peak capacity needed to start both engines and keep all systems running.

The entire system weighs only 100 kg, which is 3 times less than the traditional lead acid battery banks. Yet it complies with Loodswezen’s high standards of safety and efficiency. But most importantly, the tenders run fast, quietly and conveniently.

Thus the project illustrates how a  successful cooperation results in a sustainable industrial application.

Silent 55 sails free at sea with solar power and storage by MG

A growing number of luxury yachts is hybrid-electric. Some are even equipped with solar panels or power banks, but as these generally don’t provide enough energy to power both onboard systems and propulsion, most still rely on burning fossil fuels at least to some degree.

But that’s about to change. Enter Silent 55, the newest cruising catamaran by Silent Yachts, that relies nearly entirely on solar energy. No toxic exhaust, no noise from generators and no excessive vibrations from diesel engines. It’s virtually self-sufficient and maintenance-free.

The 55-foot vessel comes outfitted with 30 high-efficiency solar panels with a power output of around 9 kW. Using charge controllers this energy is stored in 28 high-energy Litium-Ion batteries to power both onboard amenities (through a 15 kVa inverter) as well as a its silent electric propulsion system.

The entire installation includes 2 systems, each consisting of 1 MG High Voltage Master and 14 MG High Energy Battery Modules, configured in series to achieve a system capacity of 2 x 70 kWh. Unique in this application is the unusually high system voltage of 400 VDC, while the setup is very compact and weighs only 2 x 400 kg.

A generator is on board for rough weather or emergencies, but the Silent 55 meant to cruise for weeks on end. Carefree.

Windcat Workboat sets a new standard for efficiency with batteries by MG

Windcat Workboats is Europe’s leading provider of specialist crew transfer vessels to offshore wind power industry. These high speed crafts are operated on a daily basis to ferry technicians and other personnel to and from installations in North West Europe, from the UK to Denmark and Germany.

The small yet fast catamarans are optimised to guarantee excellent quality of service, enabling the crew to perform their work offshore without delay, in a reliable and comfortable way. When it comes to operational safety the company is committed to the highest standards for international projects.

Windcat 41 is the latest addition to its fleet. This state of the art vessel, carrying 26 technicians, was built according to the latest technologies, rules and regulations. In order to comply with the industry’s energy reduction goals, while simultaneously meeting ever-increasing demands for higher comfort and performance, the 23 meter vessel was radically optimised in terms of hull design and – in stead of conventional batteries – outfitted with MG’s lithium-ion equivalents, due to their superior energy density.

The result surpassed all expectations. High performance, at a top speed of 31 knots using only two 720kW engines, with low fuel consumption and low emissions, stating a reduction of up to 40% compared to conventional designs. Which also yields a saving in costs. Thus the Wincat 41 sets a new industry standard for efficiency.

A total of four energy systems were installed, for emergency, service (twofold) and radio. Work on installing a similar setup on the next vessel is already underway. While MG’s energy systems are often used on luxurious super yachts, this projects shows they’re strong enough to perform on industrial workboats too.

Electric houseboat holidays powered by MG

Most motor- and houseboats are equipped with diesel engines. But not Elfsteden Vaarvakanties Friesland‘s rental fleet. Endorsing the need for the transition to a ‘circular economy’, the Frisian company has decided to renew their diesel houseboats with a new luxury outlook and modern techniques based on sustainable materials and energy.

Elfsteden Vaarvakanties Friesland rents out houseboats with low height, width and depth, allowing tourists to navigate the world-famous Elfstedentocht: a 200 km long circular route along canals, rivers and lakes visiting the eleven historic Frisian towns, with picturesque bridges and scenic views.

Recently the first few of eleven outdated diesel houseboats have been completely modernised and equipped with electric propulsion and engines. Depending on the vessel’s length, a number of MG Lithium-Ion HE Battery Modules are being installed, to store the green energy supplied by the solar panels on deck. A Fischer Panda generator is used as a backup supply.

The houseboats vary in size, accommodating 2 to 10 persons, and offer sustainable luxury on board. All equipment runs on 220 V, including a smart tv with wifi, radio, coffee maker, ceramic cooking and a combi oven. Water is heated by a boiler, walls and windows are insulated and an air heater guarantees a warm and pleasant atmosphere.

Comfort and luxury, combined with silent cruising for hours at a time will allow guests to enjoy the most of Frisian nature, peace and quiet. Recharge your inner battery during a holiday powered by the sun.
