The reasons I chose electric motors over Diesel engines, and the wonders of renewable energy.

The reasons I chose electric motors over Diesel engines, and the wonders of renewable energy.



To the interested! The reasons I wouldn’t go back to diesel power on Ocean Strider.



I started this journey with the intention to sail, and I’m not saying there haven’t been times when I would just like to get to my destination faster. But the priority of saving power in the batteries has made me choose the slower traditional way and use my sails.

A. Generating my own fuel is an environmental gift from nature:


1. It gives me a warm fuzzy feeling to know we’re generating charge power from Ocean Strider’s Lynch air-cooled propulsion system, as she cuts through the water under sail.
2. Then as we sail, that charge is increased by natural solar charge and wind generation.
3. After the sail if I need to motor, I can use that free power, through the propulsion system to take us to our mooring or anchorage.
4. The benefits to me and the planet are obvious.

B. A contribution to a cleaner planet:

1. I’m aware of the alleged poor manufacturing conditions for workers which must be put right, and that the disposal of parts, including batteries, is contributing to the destruction of the life-giving systems on planet earth.
2. But I believe that electric propulsion, given time will make a huge contribution to a cleaner planet, and the more it’s fitted and used the faster research and technology will create the desired end result.

C. Quiet clean and vibration free:


1. When you use an electric drive on a sailboat, it’s almost like using your sails.
2. It’s so peaceful, with almost no sound, no vibration, and no fumes ruining your journey.
3. Only pure clean free energy takes you to your destination.

D. See everyone filling their tanks with fossil fuel and paying their taxes:

1. Ocean Strider has now covered more than 6,000 nautical miles and crossed oceans since I fitted the electric motor.
2. We use the diesel tank for storage and have not paid a cent for propulsion.
3. I have a generator on board for emergencies and run it once a month for its own maintenance.
4. On a journey like this, every cent you save adds up and helps get you further.

E. Charging your boat for FREE when you’re anchored:


1. We’ve anchored for free in some beautiful bay on our travels; there’s usually sun or wind, and especially in the Caribbean, you get both.
2. Through the battery monitor I can see (even on Ocean Strider’s small solar and wind generation capably) our batteries being charged which ultimately keeps their condition good for longer.

F. Saving you money:


1. We’re currently on a slow circumnavigation of the planet on board Ocean Strider and I’m often told that what I’m doing doesn’t work and never will.
2. Well 50 years ago people were sailing, using only Diesel engines and high-power bulbs, oil lamps, and in-efficient electrical equipment.
3. They would be forced to pay for diesel to use the alternators on their engines or pay Marina fees and hook up to electric.
4. Technology is moving forward, helping to increase the power we make and to store it on board. Lowering our usage through efficient LED bulbs and power-saving equipment onboard. Incredible navigation and auto systems help get us and our sailboats to our destinations faster and safer.

Technology is moving forward and I’m sure the sailboat is the ultimate power-making and most efficient vehicle on the planet. The research and development starting point for all things electric is here.

      Love your story. I have recently converted my Currawong 30 to electric after 20 years of dreaming and experimenting.

      1. As you know I love sailing with my electric motor. It does take a while to get used to, just watch the weather, tides, and currents. Sail when the time is right to sail not because you need to be somewhere at a particular time, just like in the old days. Use your battery monitor if you have one, and fit one if you dont they make a big difference. Sorry if I sound like a teacher. Happy sailing Geoff

  1. You are using a pss stern gland, prone to reliability issues over time. This next to you electric motor, is a problem for the future. Make doubly sure you use lots of loctite on those pss grub screws, and change the bellows ahead of the suggested 7 year service life. 7 years based on regular cruising useage or 7 years based on weekend sailor useage.

    1. Not sure what you mean “this plus your electric motor”?

      1. I yhink he means when that seal let’s go, it will spray all over the electric motor. I am going to assume the motor is water tight

      2. Unfortunately, there is always a way for saltwater to find its way into the workings and wiring inside an engine bay if allowed. I’ll be careful and keep my eye on the seal. Cheers

    We went electric too and would never go back. The only problems we had were in purchasing the various components. That, and the surprisingly weird noises that a folding prop makes when you can hear it. We wrote about it as well: https://www.nxtbook.com/kerrwil/canadianyachting/canadian-yachting-october-2022/index.php#/p/42

    1. I brought the whole kit from Lynch Electric motors in the UK, including the AGM/VRLA batteries, and left the original prop on. I love it!

  3. I calculate Diesel fuel costs from Kemah, TX to Key West approximately $1000.00-$2000.00 and 1 month down the ICW single-handed…

    1. You may be right I don’t know, but I have met a sailor who has sailed the ICW. So maybe an electric motor and no diesel cost. It may be an option.
      but I don’t know that stretch of water! I hope all goes well on your cruise.

    In 2009 I fitted my Piver Victress with electric propulsion. I used an old school 48v shunt motor with the existing 3 blade 19 inch dia. prop. It had lots of grunt for fast acceleration and easily pushed the boat over 6 knots. But doing this would would over heat the controller and it would go into slow mode to cool down, about 2 knots. With only 4x 80w solar panels the recrecharge time was too long and using Trojan lead acid flooded batteries was all I could afford at the time this type of use gave them a short life. Less than 4 years.
    I am planning on electric power for my next boat and will address the main issues I had on the last by using LiFePo batteries, 800w of solar, 300w of regen while sailing and a honda genset for back up.

    1. Sounds like a good plan, and a good idea is a wind generator. I have a Rutland 1200 48v. Its quite and does a fantastic job when not sailing and no sun. happy sailing
