Electric power is used by a whole host of boats and vessels – from small tenders up to passenger ferries.

Different types of motor suits different boats. ePropulsion has electric solutions from portable outboard motors, long range and more powerful outboards able to power boats up to 5 tonnes, and inboard POD drive electric motors for day sailers up to 50’ ocean going cruising boats.

The distance you can go is determined by the size of and number of batteries you have.

Your speed affects your motoring range. Lower speeds use less energy and motoring permanently at full throttle will use most power.

Your range is also influenced by sea state, currents and windage, as with all boating under power, plus your ability to regenerate battery charge whilst underway.

For cruising sailboats your engine is an auxiliary source power, for either when there is no wind, the wind is from the wrong angle or for the start and end of a voyage – leaving your berth or anchorage.

Range examples:

24’ sailboat – set up with 3kWh motor + 9kWh battery (1 x E Series 175)
5 knots = 30 miles, 6 hours
7 knots = 21 miles, 3 hours

30’ sailboat – set up with 6kWh motor + 18kWh battery (2 x E Series 175)
5 knots = 50 miles, 10 hours
7 knots = 21 miles, 3 hours
    
The ePropulsion motors can be used with up to 16 x 9kWh batteries with give 144  hours of motoring at full power, on the most popular model the Spirit 1.0 Plus outboard motor.

Batteries can be recharged at any level of charge without any damaging effects happening to the cells.

All batteries option can be charged with solar or hybrid generated power whilst they are simultaneously in use and discharging power.

Batteries are available with a range of charging options, including 240V chargers that plug into mains power, either at home or on a marina berth standard power supply.

Batteries can also be recharged by:

• solar power supply – such as a fixed or portable solar panel
• other onboard power sources – such as a generator powered by wind, diesel, petrol or hydrogen
• using the hydro-regeneration capability on sailing boats, where at over 4 knots of boat speed the propeller automatically recharges the batteries

 Rather like filling your engine with fuel, or recharging your car, it’s about planning ahead for the voyage you are undertaking. It’s un-seamanlike to set off with insufficient fuel or water on board for any voyage and this is no different for electric power.

Just the same as you might call into a port or marina for fuel, water and provisions, you’ll call in for recharging.

Set up for your planned voyages by having:

• Sufficient batteries on board for the trip you have in mind – eg a cross channel under motor
• Combine battery power with regeneration options on board – such as hydro generation whilst sailing, solar or wind power supplies
• Hybrid sources – such as a generator (diesel or hydrogen) or portable brief case sized generator for a specific trip, on board as a back-up power supply

Plug into a 16 amp normal mains power supply at a marina and recharge overnight. More marinas, such as MDL, are increasingly providing dedicated 32 and 64 amp fast charging facilities for their berth holders and visitors.

All ePropulsion batteries are fully recyclable. They are either repurposed for another job or reconditioned for continued use.

After Lithium has been used in a battery cathode, it can be used again and again. Oil and it’s bi-products such as sulphur cannot be reused.

Are the raw materials being mined for battery use harmful for the environment?

No mining is particularly good for the environment, be it tin, copper, coal or oil. However, mankind has been mining and drilling for 1000s of years, in particular most recently for oil to power cars, make plastics and other non-recyclable bi-products for use in the developed world.

There have been numerous disasters for the oceans and environment caused by the mis-handling of oil or accidents at oil rigs.

There have been no incidents of lithium accidentally contaminating the oceans due to mining or shipping incidents.
