In terms of performance, the sharpest electric cars have caught up with and surpassed most sports cars with petrol engines, but at sea, development is slower. The electric boats have lagged behind their conventional competitors. Now, however, things are starting to move in our neighboring countries.

In 2019, Prime Minister Erna Solberg was christened a copy of domestic Evoy1. The Norwegian manufacturer Evoy AS then assumed that it was the world’s fastest mass – produced electric boat, with the capacity to deliver 900 horsepower. The highest speed at which the Norwegians had tested it was 49 knots, corresponding to about 91 km / h.

A competitor is German Say Carbon, which last year presented Say 29E. With its electric motor of 360 kW, it is good for 50 knots, or just under 93 km / h, which was considered a record for series-produced electric boats. It reported Plugboats .

Now, however, Danish Sarvo Marine has taken a real step. Their electric boat Sarvo 37 can handle 70 knots, corresponding to 130 km / h – and then it goes away on the water. Behind the driveline is the company’s technical manager Jonas Voss, who has previously led the work with Swedish Koenigsegg’s plug-in hybrid Regera.

On the website tells the company that the aluminum boat’s design is inspired by ancient Danish minesweepers. A wedge-shaped for cutting through the waves at low speed, while the underside has been made flatter towards the stern, which together provides an optimal energy saving at all speeds. It has a length of 37 feet, or 11.25 meters, and a weight of 4,780 kg – where the battery system accounts for 1,460 kg.

The electric motor can deliver 1,280 horsepower, and according to the manufacturer, it has four times as much power and torque as a Porsche 911 Turbo S of model year 2019. Instead of the propeller being completely submerged, it cuts the water surface, and the cover over the propeller reduces it amount of air mixed with the water – which contributes to increased acceleration and speed.

At the same time, the propulsion system must be 10–18 times as efficient as a conventional outboard or system with a fixed propeller. And if you choose to travel at a leisurely 10-20 knots, the battery pack of 350 kWh should give a range of 130-185 km, ie up to 100 nautical miles.

With fast charging at 360 kW with CCS standard, you should be able to get a full battery in as little as an hour. With a 60.5 kW charge, however, you have to wait 5.5 hours, and 15 hours at 400 volts – alternatively just over 47 hours with a charge at 230 volts.

The hull, with a thickness of six millimeters and a keel of ten millimeters, consists of 60 percent recycled aluminum. And even if today you do not expect tropical woods on board, it is perhaps still a little surprising that the Danes have chosen synthetic wood instead. The plastic mixture consists of 80 percent recycled material, among other things taken from the sea. The first boat for delivery will be ready in May.
