Electric Boat: Future or Reality

Are there any realistic all electric boats yet? Is the battery boat the future?

The simple answer is YES, with new technologies on batteries and motors. And that’s especially true for smaller boats – it’s also budget-wise (Check out why).

The fact is that all electric boats are tackling a lot more challenges than electric cars. It’s easy to understand that extra weight means extra momentum for cars, but for boats, it’s pure drag. That means the energy to push a car at 60 mph can only probably push a boat at 30 mph.

However, just like trolling motors have now become a standard for the fishing community to provide a quiet trolling experience, the higher power electric motor for larger boats is also possible today.

The most critical thing is to make sure the electric powered boat options can satisfy your requirements within your budget. The best way to answer the question is to check what the electric boat technology can offer today so you can make your own decision.


It’s safe to say that you can find an electric boat and battery boat solution for almost all your boating applications today, especially for leisure boating requirements.

A surprising fact is that the power range for the electric powered boat motor can go up to 460 kW, equivalent to 600 HP. That’s tremendous power for electric boats, allowing you to reach a maximum speed of 50 knots on a 30ft boat and cruise at an extensive range.

While the monstrous 600 HP battery powered boat engine is enticing, it’s not for everyone due to the price, availability, and also the market demands.

More common and readily available high-power electric boats go at a power range of about 100 kW. For example, the ePropulsion H-100 electric inboard motor provides 140 HP equivalent power, suitable for larger sailing boats and motor vessels between 60 to 100’ (18-30m) with a full displacement of up to 200 tons.

You may also find some smaller all electric boats equipped with electric motors below 10 HP, such as the 9.9 HP Navy 6.0 and 6 HP Navy 3.0. This setup is getting very popular as it’s affordable and provides so many advantages over combustion alternatives.


The range of electric boats and battery boat can be a huge concern for many boaters. No one wants to run out of juice in the middle of the water.

The fact is that the range of battery powered boats varies among different applications, and it depends on a lot of factors, including the battery capacity, hull types, and sailing speed.

The range of electric boats has been greatly extended due to the modern battery and motor technologies.

According to the statistics, the most powerful electric boat today can provide you with about 50 nautical miles in planning speed and over 200 nautical miles in cruising speed, which can already cover most of your boating needs.

So if you plan to go electric, you can always find a solution.

If you are looking for a pontoon electric boat or electric solutions to outfit your dinghies or any other leisure boats or smaller vessels, you will have many affordable options that provide you with decent speed and range, including the following:

 PowerRange @ top speedRange @ 1/3 speedBattery
Navy 6.0 Evo6 kW (9.9 HP)22.5 miles45 milesE175 (8960 Wh)
Navy 3.0 Evo3 kW (6 HP)13.6 miles49.3 milesE175 (8960 Wh)
Spirit 1.0 Evo1 kW (3 HP)7.8 miles80 milesSpirit battery (1276 Wh)

*Data collected on a 12-foot aluminum boat with one person onboard in calm water conditions.

As you may have noticed, electric boats can have extended range and runtime if you adjust them to lower speed settings. That’s to say, you can go fishing all day long at trolling speed.


Charging is easy with electric boats and battery boat, given that the most marina’s offer shore power which can be used to charge your electric powered boat on a standard 16a socket.  Some lightweight electric motors, including the 3 HP Spirit 1.0 Evo, feature an integrated lightweight battery that allows you to remove it easily and take it home for quick charge.

Generally speaking, you can get your electric boat charged overnight, and some electric motor batteries support fast charging and can be fully charged within a few hours.

Charge TimeFast ChargingStandard Charging
Spirit Battery (1276 Wh)3.5 hours*8.5 hours
E175 battery (8960 Wh)3.5 hours**7 hours

*Data is tested with fast charger which requires a separate purchase.
**Data is collected using three chargers in parallel connection.

Besides that, electric boats and battery powered boats usually support various charging options, including solar panels and wind turbines. If you are a sailboat owner, you may also enjoy the convenience of hydrogeneration that allows the batteries to get charged from wind and water.

If your were looking at repowering a 30ft sailing boat with electric, the weight difference is very mimium compared to the orginal motor and fuel tank. It can often mean you can get the weight position in a more central placement in the vessel.

Another good news is that the heavy and less efficient lead-acid battery is no longer the only or preferred choice for building an electric boat and battery boat.

With the advances in battery technology, you now have better options to make the full electric boat solution work for you. 

Currently, the lithium battery (LiFePO4 battery, to be more specific) provides you the best answer to build electric boats, thanks to the following benefits compared with the traditional lead acid batteries:

  • Lightweight: 70% less weight 
  • High efficiency: 50% more useable capacity
  • Compact: Takes 50% less space
  • Long lifespan: Lasts 4 to 5 times longer
  • Competitive price: Unit price is as low as $0.5 per watt-hour
  • Safe: Zero leak and fire risk
  • Easy to maintain: No maintenance is required

So what’s the weight exactly? Let’s take the ePropulsion E-Series battery as an easy example.

E402048 Wh28 kg / 61.7 lbs16.5 × 15.4 × 8.2 inches
E804096 Wh53 kg / 116.8 lbs21.9 × 17.3 × 8.4 inches
E1758960 Wh87 kg / 191.8 lbs19.7 × 22.2 × 10.9 inches

Modern batteries are lighter-weight and cost-effective with a long lifespan and minimal maintenance, making electric boats a more viable option than ever.

The price is a big factor to consider for the electric boat and battery boat conversion, and this includes the price for the motor and the batteries.

It’s worth mentioning that the modern LiFePO4 battery is not only efficient but also cost-effective, thanks to its greatly increased usable capacity. For example, the E-Series battery only costs about $0.5 per watt-hour, making it affordable for leisure and commercial uses.

Although the price for electric boats has dropped over the years as the technology improves and more competitors come into the market, you will still find the initial cost of electric powered boats can be higher than their combustion counterparts.

However, if you consider the cost in the long run, you might come to a different conclusion. That’s due to the cost savings of electric boats in fuel bills and lifetime maintenance.

You will eventually find electric boats cheaper after a few years of use. Here is a chart that compares the cost of electric powered boat motors and combustion motors in the same power range:

Electric Boat vs Combustion Boat

Besides that, you will gain a lot of benefits if you go with the higher initial payment method.

Top 5 Benefits of Electric Boats

If the current electric boat and battery boat technology works for you, you can unlock tons of benefits from it. In fact, some are using the electric powered boat motors as a second or kicker motor to serve part of their boating needs, such as getting on and off a mooring or in and out of the marina.

Electric boats and battery boats provide a premium boating experience you can never imagine with the petrol and diesel rivals. Let’s check out what you can expect from electric boats.

  • Quiet: The electric boats are virtually silent. Perfect for not spooking fish when you are fishing.
  • Clean: There isno messy fuel or oil leaks with battery powered boats, and therefore no greasy stains on your hands, car trunk, or boat.
  • Low maintenance: Significantly lower maintenance required than combustion engines. (Click to learn more about the electric boat maintenance)
  • Eco-Friendly: It’s exhaust free and can be recharged with hydrogeneration, wind turbine and solar panel.
  • Future-Proof: The battery powered boats enable boaters to access waters where combustion engines are banned.
  • Easy to use. Forget about the pull-starting and warming up the engine. Just press the button and twist the throttle, and you are on your way.
