Torqeedo, the same company that made a name for itself building viable electric outboards, now appears ready for the big-time with its new Deep Blue Hybrid system for boats from 40ft to 80ft. Employing the same motors found in the company’s larger outboards, Deep Blue represents a fully integrated system of high-end components of 18 different types connected by four different types of circuits. Although custom systems of this type have existed for a while, the advantage to Deep Blue is that boatbuilders and owners now have the benefit of a hybrid drive comprised of “carefully matched and integrated components with a single company responsible for the functionality of the installation and its compliance with regulatory standards.” In other words, what Torqeedo is offering is a reliable turnkey system with the backing of a single, established manufacturer, eliminating what has thus far proved to be a major hurdle to this kind of technology truly going mainstream.
Colorado River Discovery is going to mark the 100th anniversary of the National Park Service by introducing a new, completely electric raft used to travel down the Colorado River.
Colorado River Discovery, a group that takes tourists on trips down the Colorado River, has been working on the raft for 10 years. The raft is named Helios, in homage to the God of the Sun in Greek mythology.
“A company called Torqeedo, which is based in Germany, developed an incredibly efficient, 100-percent electric outboard motor that we have put on this raft,” Korey Seyler, general manager at Colorado River Discovery, said.
Seyler said the raft will not produce any emissions and will run from power from a charging station at Glen Canyon Dam.
“It’s actually produced by hydroelectric power that charges this, so that’s what brings the zero emissions out,” he said.
The company has been setting aside money since 2006 to pay for the raft, Seyler said.
“We’ve actually set aside $1.50 for each guest we take down the river over the past 10 years in order to help with the research, development, and manufacturing of this raft,” he said.
Seyler said customers can start riding the raft this spring after its official launch on Earth Day, Apr. 22.
Hapag-Lloyd Cruises has become the first cruise operator to install eco-friendly electric motors onboard the rubber Zodiac boats on its expedition vessels, Hanseatic and Bremen.
Used to take guests to inaccessible areas in some of the world’s most remote regions, the Zodiacs have been equipped with Deep Blue electric motors from German manufacturer Torqeedo. The 80 horsepower motors have been piloted over the past year and showed a ‘previously unseen level of output’.
Unlike combustion motors, the Deep Blue electric propulsion system does not release emissions or harmful substances into the water, helping to protect the vulnerable waters Hapag-Lloyd’s excursions visit. In addition, the motors are ‘considerably quieter’ than the Zodiacs’ previous 36 horsepower motors.
“For years, Hapag-Lloyd Cruises’ ships have used low-emissions marine diesel in fragile cruising areas such as the Arctic and Antarctic, and equipping our expedition Zodiacs with electric motors represents another investment in the future of our environment,” said Karl Pojer, CEO of Hapag-Lloyd Cruises. “With their flora and fauna, our cruise destinations are key to the appeal of our itineraries and we want to protect what fascinates us.”
Torqeedo has introduced a new flagship model for its low-voltage Cruise line, the Torqeedo Cruise 10.0. The 20 horsepower-equivalent, emission-free outboard can plane light boats at speeds up to 28 mph and moves displacement hulls from 3 to 10 tons at up to 9 mph.
“Torqeedo’s range of products encompasses systems from 1 hp all the way up to the 80 hp high-voltage Deep Blue. The Cruise 10.0 provides a clean, green and quiet alternative for commercial and recreational users who prefer the simplicity and easy handling of a low-voltage system, but require more speed, thrust and power than previously available,” said Steve Trkla, president and general manager of Torqeedo, Inc.
The Cruise 10.0’s electronically commutated, brushless DC motor and optimized propeller provides up to 12 kW at peak input and 10 kW continuous power. It comes standard with an integrated electric tilt, mounts to the vessel’s remote steering and is available in three shaft lengths.
The 5 hp and 8 hp equivalent Cruise motors were redesigned in 2015 to include a rugged aluminum lower unit, full waterproofing to IP67 and corrosion protection. These features are carried forward into the Cruise 10.0, including a full display showing battery status, GPS-calculated range and speed, and up-to-the-minute data regarding remaining runtime.
The Power 26-104, a marine lithium battery, is included with the Cruise 10.0. The 25.9V power packs replace two 12V lead gel or AGM batteries, saving up to 70 percent of the space and weight.
The Cruise 10.0 is compatible with Torqeedo’s smartphone app, TorqTrac, allowing users to view motor, GPS and mapping data in real time and in full color. A tiller-steered version is expected for 2017.
Torqeedo’s high-voltage motor in the commercial environment
In the field of physics, work is said to occur when a force that is applied to an object causes a displacement of that object in the direction of the force. Going off this definition, the high-power Deep Blue 80 electric motor is a true workhorse.
A workboat equipped with a Deep Blue is used to maneuver barges on the quarry lake Rogau near Frankfurt. Considering that these barges consistently carry over 60 metric tons of gravel, this application impressively demonstrates the unparalleled performance of the high-voltage electric motor.
Pushing tremendous loads
In order to protect the local groundwater, the gravel quarry Kaspar Weiss decided to equip their workboat with the zero-emissions Deep Blue system. At their Rogau location the quarry yields countless tons of gravel annually. However, this commercial extraction of gravel results in vast amounts of useless byproducts such as sand, mud, clay, and rocks. With the help of a workboat and barge, these byproducts are removed. The Deep Blue powered workboat locks onto the barge to maneuver the 60 tons of unwanted material to the dumping location. In this way the Deep Blue helps remove over 700 tons of material from the Rogau quarry lake each day.
Traits for success
Developed by Torqeedo, the high-power Deep Blue propulsion system is well suited to applications involving heavy loads. Fed with 65 kW of electrical energy, the Deep Blue system achieves a propulsive power equivalent to an 80hp petrol outboard, making it the world’s most powerful electric outboard operating at an efficiency of 54%. As a result, the Deep Blue achieves a static thrust of up to half a ton, which represents performances that were previously unheard of in this category. It is precisely these performance characteristics that allow the Deep Blue to be successful in the quarry application, as a large propeller is need to generate the thrust necessary to move the 60 ton barge. Thanks only to the high torque of the Deep Blue is it possible to use an appropriately large propeller.
Power and endurance
The necessary electricity for the Deep Blue is provided by lithium batteries, which store a total of 26kWh of electrical energy. The batteries make use of the latest advancements in automotive lithium battery technology and are adapted to the marine environment. Torqeedo, the global market leader for electric marine propulsion systems, provides a nine year capacity warranty for its batteries. This warranty promises that after nine years of daily use the batteries will still have a capacity in excess of 80% of the original capacity.
The quarry-lake Rodgau is not the only site of commercial use for the Deep Blue. The high-performance system is also employed as a propulsion solution for water-taxis, ferries, patrol boats, and excursion boats.
A new unmanned vessel, launched with the help of Google, will map shorelines and raise awareness of the impacts of global sea level rise. The high-tech boat boasts innovative technologies from the boatbuilding, propulsion and mapping fields.
“It’s a Google Boat,” says staff scientist for the San Francisco Baykeeper organization, Ian Wren.
The small, remote-controlled catamaran, a Wave Adapted Modular Vehicle (WAM-V) designed by Marine Advanced Research, features an adaptive hull design that flexes to adapt to the water’s surface and provides ultimate stability. Originally designed to be worn by backpackers, Google’s proprietary Street View Trekker camera system was provided on loan to the Baykeeper organization, allowing them to create stunning, bay-level maps. Clean, powerful and efficient propulsion was a high priority. The group turned to electric propulsion innovator Torqeedo for that task.
The Baykeeper organization plans on using the imagery collected — nearly 500 miles of coastline ranging from San Jose to Antioch, California — on its website and for educational purposes, helping illustrate the threats posed by global sea level change to critical wetlands.
“A lot of people know about sea level rise,” says Sejal Choksi, an environmental lawyer and Baykeeper’s interim director. “We are hoping these images will really bring the reality home to the public, that they will look at pictures of places they know and say, ‘Oh my gosh, this is going to be underwater.’”
Baykeeper’s WAM-V sports twin Cruise 4kW electric outboard motors rigged with Power 26-104 lithium batteries. The WAM-V is able to run for hours with nearly zero environmental footprint, thanks to onboard traditional and solar charging capabilities.
The Google Trekker, WAM-V and Torqeedo technology has also recently completed a mapping project of American Samoa that can be seen here.

A German company has developed a new approach to building workboats. Instead of doing the whole of the construction in a boat yard, Ophart Maritim builds a range of hulls in aluminium and supplies these to owners or other shipyards for completion and fitting out.
The Opship hulls are supplied as the basic open hull, what the company calls a Boat Chassis, which gives the recipients a proven design on which to develop their own ideas for the completed vessel.
The aluminium hulls are designed in three sizes and they are all based on a unique hull design that features a moderate vee hull with wide chines for easy planing. There is a deep narrow forefoot to improve the low speed handling and a flare in the bow to provide a dry ride.
The hulls are primarily designed to accommodate outboard power with up to triple 300 hp outboards on the largest of the hulls to give high speeds. To fit these power units a bolt-on module is attached to the transom. Fuel tanks can be specified if required. Alternatively the hulls can be specified for electric propulsion using the range of Deep Blue 80 electric outboards produced by Torqeedo and with a battery pack to offer range of over 50 miles at low speeds but with the larger electric outboards, a speed of 12 knots can be achieved but with a more limited range.
The aluminium hulls are fully welded using 8 mm plating and fitted with closely spaced transverse framing. This framing is both welded and glued in place, the glue creating a form of insulation that is designed to reduce the sound. An interior deck can be supplied over the frames or these can be left exposed for the final builder to complete as required.
The concept of the hulls developed by Ophart Maritim is to offer an advanced and tried and tested hull concept at an attractive price. These hulls are designed to meet the demands for a wide variety of workboat roles from fast patrol boats to rugged harbour workboats. They are currently produced in sizes from 8 metres up to 12 metres and one of the main advantages is the quick delivery time. Also by focussing on just producing hulls in aluminium Ophart is able to invest in advanced construction techniques.
