As one of the most respected brands in Europe, Nimbus shoulders a responsibility to influence environmentally sustainable thinking. Our corporate policy is to take great pains over building boats that enhance the relationship between boats, people and the environment. We have a vision; the increased freedom of people to move at will across the sea shall not be achieved at the expense of the environment.
We started our electric ambition already in 2009 and have had an electric powertrain as an option for three of our boat models since 2015.
Smart Speed Concept
Comfort and safety before speed
Smart Speed features a hull designed for comfortable driving at speeds from 0 to 22 knots. The speed can be adapted to sea conditions for higher safety, better comfort and the best possible experience at sea.
At Nimbus our concern is that a boat should run comfortably at the speeds at which it is used. We know that Coupé owners are fond of cruising at speeds from 4 to 20 knots, when boats normally produce large wake and burn a lot of fuel. For the 305 Coupé and 305 Drophead we have designed a hull that rides comfortably throughout the entire speed range. In practice, the 305 has no real planing threshold and returns low fuel consumption at all speeds. Speed can be adjusted to weather conditions, which provides better safety, comfort and the best possible ride from which to appreciate your natural surrounding.
The E-power concept
As a result of our business concept, we have set a course for the future in which environment issues play an increasingly important part. In line with this ambition we have introduced our E-Power Concept. The E-power Concept, also known as “Environmental Power”, represents Nimbus environmental thinking for the future, in which we include the entire boat-building process from production engineering to climate-smart materials. We also look closely at construction engineering and hull design to attain ultimate propulsion, striving to achieve a state in which the entire chain makes as little impact as possible on our environment.
We currently offer the 305 Coupé and 305 Drophead with an electric engine and powertrain.
Torqeedo electric Deep Blue 50i 1400
with BMW i3 42.2 kWh batteries
The boat is fitted with a Torqeedo Deep Blue 50i 1400 rpm drive with a 42.2 kWh BMW i3 battery. Charging takes 16 hours from a 230V source or 8 hours from a 380V. Cruising speed between 5 to 8 knots provides optimal combination of speed and good range. The installation can be upgraded with an optional battery pack to include two BMW i3 fast charging batteries 2 x 42.2 kWh totalling 84.4 kWh.
With a cruising speed of 5.7 knots the boat have a range of *53 Nm. At 3.7 knots the range increases to *86 Nm.
Torqeedo is one of the world’s leading manufacturers of electric drives for marine use, both private and commercial. Deep Blue 50i 1400 is a proven system in use worldwide. The 305 Coupé and the new 305 Drophead E-power can be ordered as from this time. The boats are built on order.
* Please note that range vary depending on conditions at sea.
High Power Electric Propulsion
More than just a battery powered electric motor, Deep Blue electric propulsion is a fully integrated high power system, exclusively providing efficient, clean and comfortable mobility on the water. The system is electrically charged in the port, energy is efficiently stored in high end lithium batteries and used thereafter for powerful and comfortable low noise and zero emission propulsion up to 50 kWh input power per motor.
Electric motor and battery technology have developed quickly in recent years. We had already allowed for electric power in the design when we entered the construction stage of the new 305 platform. The bottom of the 305 is optimised for lower speeds (0-22 knots) and designed to function well with smaller engines. Consequently, the Torqeedo electric motor suits us perfectly
