Canadian company Robert Allan is introducing an electric pilot boat called RAlly 1600-E for short trips. The vessel is made from aluminum and equipped with a fairly decent amount of batteries – 815 kWh, that will be recharged from shore power.
The two electric motors are rated for 500 kW each, so total 1 MW of power, totaly fine for speed of 20 knots.

- Length overall: 16 m
- Beam: 5 m
