The hull speed of the DutchCatTwelve is 8 kn (almost 15 km/h). Because of its multihull shape, at speeds above the hull speed, the ship will remain much more level than a monohull ship; as a result, cruising above the hull speed is very much an option.
The optimised underwater ship of the Comfort version achieves an unprecedented low drag, making it possible to cruise the whole day on electric power.
The “Comfortable shoes” contribute to minimising the energy demand. At a speed of 4,5 kn (8 km/h), just 6 kW of energy is required.
The electrical drive consists of:
two 10 kW electric motors
one 48 kW battery pack
intelligent regulation and charging equipment to ideally harmonise everything and also provide the entire DutchCatTwelve on-board grid.
The hybrid-electric version consists of the electric package as described above linked to a power supply that provides the necessary electricity.
The diesel power train consists of two 3-cylinder, 29 hp diesel motors.
Hybrid-diesel is configured from the diesel power train, which is connected in parallel with the electrical drive of the fully electric version; really, it’s two power trains in one.
The electrical drive consists of:
