OceanVolt AXC 30: New 30 kW Continuous Inboard Targets 50-Ft Bluewater Sailboats

OceanVolt has unveiled the AXC 30, a 30 kW continuous (60 kW peak) inboard motor designed specifically for bluewater sailboats in the 45–55 ft range. The motor is the first OceanVolt product to use a 96 V DC bus as its primary architecture, halving DC bus current versus a 48 V design at the same power and meaningfully reducing main cable cross-section and fuse sizing.

The motor uses a wet-stator liquid-cooled permanent-magnet synchronous design with continuous duty rated at 30 kW for 60 minutes at 40 °C ambient seawater inlet — a meaningful step up from the typical 20-minute continuous ratings on competing inboards in this power class. OceanVolt has publicly committed to a 5-year / 20,000-hour motor warranty for the AXC 30, the longest in the leisure-marine electric segment.

In propulsion terms, the AXC 30 produces 240 Nm continuous shaft torque at 1,800 rpm, allowing larger, slower-turning propellers (typically 22–24 inch four-blade) for improved efficiency at displacement speeds. OceanVolt's regenerative firmware, previously only available on the variable-pitch ServoProp range, has been ported to the AXC 30 with a fixed-pitch optimisation; field-trial data shows 200–600 W of regen at 6–7 knots boat speed under sail with a freewheeling fixed prop.

For a 15-tonne aluminium cruiser targeting 7 knots, OceanVolt cites a 60 kWh pack giving 35 nm of motoring range — sufficient for the typical motoring legs of an offshore passage. Combined with the regenerative capability and a 4 kW solar bimini installation, the company estimates that 60–70% of a typical Atlantic crossing's motoring energy can be recovered without burning fuel. European retail pricing for the AXC 30 motor and motor controller package is approximately €12,800 excluding battery.
