Vessel & propulsion
Hull, displacement, propeller or drivetrain and the existing propulsion system.
Electric & hybrid propulsion
Start with how the boat is actually used.
A practical engineering assessment of whether electric or hybrid propulsion fits the vessel, its duty cycle and the available charging.
An open assessment
The technology follows the requirement.
Sometimes the right answer is to keep the diesel. The assessment starts with how the boat is actually used, not with a predetermined technology.
Range, reserve, weight, space, charging time and the existing drivetrain all affect the answer. The objective is a workable recommendation, including improvements to the current system where that is the stronger option.
Assessment method
Six connected decisions.
Duty cycle
Cruising speed, typical passages, operating hours and reserve requirement.
Energy requirement
Propulsion demand alongside the boat’s domestic electrical load.
Energy storage
Battery capacity, chemistry, usable energy, weight and installation constraints.
Charging
Shore power, solar and other appropriate charging sources.
Recommendation
Electric, hybrid, retain the existing propulsion, or improve the current system.
A recommendation you can test against real use.
The result should explain the practical limits as clearly as the potential benefits, so you can decide whether to proceed, refine the proposal or keep and improve what is already aboard.
Electric & hybrid
Thinking about changing your power system?
Start with the boat and how you use it. We’ll assess the practical demands before recommending a technology.
