What this video covers

The XC47 is a new cruising sailboat from XJ fitted with a newly developed 30 kW Oceanvolt electric motor — double the 15 kW maximum previously available from Oceanvolt.0:40 Earlier Exxos builds used two 15 kW units; this boat runs a single 30 kW motor, simplifying installation.0:58 The 47 kWh battery bank is comparable to a Volkswagen ID.3.1:07 At 6 knots the range is 25–30 nautical miles; at 4 knots consumption drops to 5 kWh, giving roughly 10 hours of motoring and a range of 40 nautical miles.1:21 At full throttle the motor reaches 7.5 knots, slightly below a diesel's top speed.1:30 The system runs on 48 volts, which avoids specialist installation but requires thick, expensive cabling; Hanse has chosen a 100-volt system for comparison.2:08 Total system price is close to 1 million NOK, though a price reduction is expected.2:31 Under sail at 8 knots the current saildrive regenerated 500–600 watts without measurable speed loss; a forthcoming Oceanvolt servo-prop drive is expected to produce up to 2 kW of regeneration.3:13
