A Dufour 470 fitted with a hybrid electric motor system — priced approximately 1 million Norwegian kroner above the standard model — completes a weekend cruise of roughly 180 nautical miles through Stavanger, Skudenes havn, and deep into Ryfylket, including Skatveit.1:23 The crew tests range anxiety, charging in marinas, regeneration under sail, and generator efficiency across varied conditions. At 6.5 knots the electric motor draws 11 kW — exactly what the onboard generator produces while burning 4 liters of diesel per hour, matching the fuel consumption of a conventional 57-hp diesel at the same speed; above that threshold the hybrid system uses more diesel than a straight diesel engine.17:50 Full throttle pulls 17 kW and reaches 7.5 knots, draining the battery in 90 minutes.17:16 Regeneration at 6.5 knots yields roughly 1 kW with negligible speed loss but produces an irritating hum that undercuts the quiet sailing experience.3:18 A 400-volt battery fault overnight prevented the 12-volt bank from charging, blocking generator start — shore power resolved it, but the crew notes a solar panel would be the only fix in a remote anchorage.16:02 Marina charging at 1.5 kW refilled the day's consumption in three hours.7:54 The practical conclusion: the hybrid earns its premium through quiet, precise maneuvering and comfort in light-wind sailing, but sailors who motor fast will burn more diesel than with a conventional drivetrain.
