New Torqeedo Might Be The Green Go for Your Dinghy

New Torqeedo Cruise 4.0 R Electric Motor Has High Thrust and Efficiency

Torqeedo, the German company that produces those cool, skinny electric outboard motors has introduced a new model — the Cruise 4.0 R — that has the power to realistically be considered a replacement for the gas-powered outboard on your dinghy.  And it does so with an overall efficiency of more than 50%, which is at least an order of magnitude greater than other electric motors, and much higher than any gasoline outboard.

The Cruise runs on 48 volts and offers 215 pounds of thrust, roughly equivalent to a 9.9hp gas outboard.  The Cruise 4.0 R is designed specifically for remote steering and throttle.  The throttle mount includes an LCD display that shows remaining battery charge, current speed and range remaining at current speed, as well as input power in watts.  The motor’s onboard computer includes its own GPS receiver, which enables the speed and range calculations.

The Torqeedo Cruise 4.0 R addresses one of the principal shortcomings of electric motors as primary propulsion on boats, which is the short range and time of operation due to limited battery capacity and relatively low efficiency.  With its significantly higher efficiency, and with a power output that should be sufficient to get a typical 10 or 11-foot dinghy to speed with a full load, it can truly be considered a potential replacement for the gas motor.

Another potential advantage not cited by Torqeedo might be the ability to eliminate the carriage of gasoline for the tender.  All trawlers and passagemaking boats on the water have sufficient electricity generation capabilities to keep the Torqeedo’s batteries charged.  And with no mess or the inherent danger of gasoline storage and management, it offers a safety enhancement.  The motor operates on lead-gel or AGM batteries, or a set of two high-performance lithium-manganese batteries available from Torqeedo. 

The motor is not cheap, with a suggested retail price of $3,699, but the extra thousand or so compared to a gas outboard motor might be more than made up by the economy, efficiency and safety of operation.
