Price on request
Carbon vacuum-infusion sandwich day boat built in Germany, 6.45 m and from 600 kg, for six. Shares its drivetrain range with the larger 777 Evolution: 11 kW with a 16 kWh pack, 60 kW with 40 kWh, and 125 kW with 81 kWh, for 11, 27 and 45 knots. Range at a 10 km/h setting is 75, 150 and 220 km respectively; at top speed the 125 kW version covers 35 km. NERO publishes no price for any configuration — all three are quoted on request.

Top drivetrain, 250+ kW peak. Range is 220 km at a 10 km/h setting, about 19 hours; at the 45-knot top speed NERO quotes 35 km in 40 minutes. Price to be announced, so the fastest version of this boat has no published price.

Entry drivetrain. Range is NERO’s 75 km at a 10 km/h setting (about 18 hours), not at the 11-knot top speed, where the figure is 26 km. Price on request.

Middle drivetrain, 90+ kW peak. Battery is 40 kWh — smaller than the 60 kWh fitted to the same drivetrain in the 777 Evolution. Range is 150 km at a 10 km/h setting; at the 27-knot top speed NERO quotes 38 km. Price to be announced.
What a buyer should know
The smaller half of a two-boat range
The 645 Voltara is NERO's 6.45 m boat, and it is best understood next to the 777 Evolution: same yard, same carbon vacuum-infusion sandwich construction, same three drivetrains, a metre and a third shorter and around 900 kg lighter. From 600 kg for a six-seat 6.45 m hull is genuinely light, and it is what lets the same 125 kW drivetrain that pushes the 777 to 45 knots do the same here on a smaller boat.
The 60 kW middle option is the one place the two boats differ mechanically: 40 kWh here against 60 kWh in the 777. So the middle Voltara trades range for weight rather than matching its bigger sister.
What the numbers do and do not say
Range is published in kilometres at a 10 km/h setting — 75, 150 and 220 km across the three drivetrains — and separately at top speed, where the fastest covers 35 km. Those are the honest pair of figures, and the gap between them is the whole story of an electric planing boat. Charging time is not published for any configuration.
No price, for any version
Every drivetrain is listed "on request". That is a legitimate position for a low-volume carbon builder, but it means this boat cannot be compared on price with anything until you have asked. Treat any figure quoted elsewhere as unverified until NERO confirms it in writing, and establish the VAT basis at the same time — the 777's published price is a net figure, so the Voltara's is likely to be quoted the same way.
Written from the builder’s published specifications and the wider market, not from testing the boat ourselves. Always confirm figures with the manufacturer before committing.
