About the WAVE 300
Best For
- Six- to ten-metre planing boats
- Commercial RIB, fishing and passenger applications
- New builds able to accommodate a large 540 V battery system
Performance in Context
The 300 hp label refers to the 225 kW peak available for 60 seconds, not continuous output. Sustained output is 150 kW. ExploMar publishes estimated consumption of 2.5 kWh per kilometre for several packaged systems, but actual consumption depends heavily on hull, displacement, speed and conditions. No single range number applies because the company offers 180, 240 and 270 kWh configurations. Buyers should obtain a hull-specific prediction at both cruise and maximum continuous power.
Battery and Charging
Published battery choices include a 180 kWh NMC system, a 270 kWh NMC system and a 240 kWh semi-solid system. The 180 kWh pack alone is listed at 1,080 kg, illustrating why installed-system weight matters more than motor weight in isolation. Charger options include 7 kW portable AC, 40 kW movable charging and a 120 kW dual-gun station. Battery chemistry, pack cooling, shore infrastructure and the boat's duty cycle should be specified together.
Availability and Pricing
ExploMar supplies the WAVE 300 by quotation through its own sales operation and regional distributors. Published packages combine motor, battery, SmartCaptain controls and charging equipment. A proposal should identify the exact battery chemistry and capacity, charger, shaft length, installation responsibility, system weight and performance assumptions.
