Show full description
The hull measures 9.28 metres and, with the engines fitted, is 9.73 metres long, with a beam of 2.99 metres and a draught of 0.84 metres with the engines lowered. The unladen weight without engines is 2,620 kilograms; the maximum load capacity is 4,250 kilograms. The yard certifies the vessel in CE design category B for six persons and in category C for eleven persons.
The propulsion system consists of two E-Motion 180E outboard engines with a combined output of 270 kW, or 360 hp, and 780 newton-metres of torque at the propellers. The battery pack has a capacity of up to 172 kilowatt-hours at approximately 750 volts DC and provides a range of up to 70 nautical miles. Charging can be carried out using a standard 220-volt shore power connection. The cruising speed is 30 knots, whilst the top speed ranges from approximately 50 to 60 knots, depending on the specification.
The motors and batteries are liquid-cooled, and a touchscreen on the helm displays the charge level, the remaining range and navigation information. The yard states that this model is only offered in the United States and Canada, which matters for buyers in Europe.
