Trawler yacht electric / hybrid propulsion
Heavier displacement, longer hours — usually a hybrid case rather than pure electric.
What this segment looks like
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.
- 96 V minimum — at trawler currents, anything lower turns into prohibitively thick cable.
- Plan around hybrid: 6–8 hours silent cruising, generator for offshore runs.
- Battery sizing is driven by silent-running requirement, not full crossings.
- Hydro regen is meaningful only on sailing-trawler hulls, not pure power boats.
