Trawler yacht electric / hybrid propulsion
Heavier displacement, longer hours — usually a hybrid case rather than pure electric.
Not an exact match? The wizard adjusts to your real numbers — these are reference hulls for the typical sizing.
Calculated by the configurator for the example boat below, sizing the pack for 2 hours at the motor's full rating with reserve. Open it to change any input.

Why a trawler yacht is a sensible repower target
Full-displacement trawlers (Nordhavn, Beneteau Swift Trawler, Grand Banks) running 15–25 t at 7–8 kn are pure-electric only for short hops. Most realistic projects are hybrid: a generator or DC-coupled diesel for crossings, batteries for harbour and silent running.
- At 25 kW even 96 V means a design current of about 480 A — at 48 V it would be about 870 A.
- Plan around hybrid: batteries for harbour and silent running, a generator for passages.
- Battery sizing is driven by silent-running requirement, not full crossings.
- Hydro regen is meaningful only on sailing-trawler hulls, not pure power boats.
