I designed my Solar, LiFePO4, 5k Inverter system after the course
For my boat project I installed a 2kW solar system with 16kW LiFePO4 battery and a 5k inverter. I learned all the details on how to do this, what to look for, best practices etc. from BoatHowTo. All the information and much more is in one place in easily digestible chapters, often with animation and supporting media. I had three certified electricians look over my installation over a period of a year and every one was impressed by the design and implementation. The quality of the courses speak for itself.

I home built my electric inboard powered 25’ sailboat over the past 4 years. When it came time to figure out the electrics for the boat I found Nigel and his new Boat How To site. I learned how to lay out buss bars, wire size and what fuse protection, switching and batteries. At the end of the course I learned how to use internet tools to do a full schematic. Excellent course!

For anyone doing DIY electrical on their boat, this knowledge is a must for safety. I learned many things I was doing wrong, even though I have some experience. Videos are comprehensive and clear. Knowledge of presenters is outstanding. Technology is easy to use.

From a reasonable amature to a confident expert. Super excellent training!
I already knew quite a bit about boat electrics. But I wanted to deepen my knowledge, understand even better the 'why' behind best practises, understand the ISO standards and the reasoning.
BoatHowTo delivered exactly that. It gave outstanding value. I got super valuable knowledge and background information. Their online response to questions is of great value as well.
After the training I confidently undertook a large LiFePo4 upgrade and rewiring on m boat.
Absolutel recommend BoatHowTo .. simple the best source of knowledge on these topics!
I learned a lot in this course and it is worth your time and money
I learned a lot in this course and it will guide me in designing and installing a Victron inverter system in my boat

Highly recommended.
I have signed up for all of their classes and have learned more from them than I picked up in 30+ years of sailing and reading instructional books, and they are fun to watch. Highly recommended.
The courses are even better than I could have expected. I've learned a lot, very quickly. They do a great job explaining things in a simple to understand manner.

After completion of both the electrical and engine courses, my wife (never been on a boat before) and I left on our new to us 60+ foot "high latitude explorer yacht" for our 4-month shakedown cruise on the Baltic Sea. Not only did these courses provide a great amount of confidence, but the specifics in the course also gave me the background to troubleshoot and fix many issue ... not to mention the knowledge to understand how the many systems functions.

Very cool, thanks for sharing your story! Sounds like you are in for quite a few epic adventures on your boat!

Both Nigel and Jan bring a positive attitude to problem solving. Very few of us are expert physicists, chemists, technicians, etc. BoatHowTo navigates the student through challenging subjects with logical progression, fun anecdotes, and satisfying solutions.

A very well organised online course. The chapters are structured and cover all areas, from the basics to the semi-professional area. All participants can set their own learning pace. Highly recommended.

Better understanding of underlying details of the electrical system on a boat
I followed both the Boat Electrical 101 and the advanced. Being a technical person and a sailboat owner for over 25 years it helped me to get a better understanding of underlying details of the electrical system on a boat and therefore being able to understand and implement/alter such a system on my boat with a higher level of safety and reliability.

Ive been following Nigel Calder for decades, since he wrote the 12v bible. Jan is excellent at delivering the talks but you have to keep up, he goes quickly.

Thanks William! Regarding the speed of the videos: You can slow down the playback by clicking on the little settings icon (the cog) and then choose for example 0.75x playback speed. I hope this helps. Best, Jan

I purchased the Boat Electrics 101 course and then the Diesel Engine course. I'm a long time boater, but not a systems expert. Both courses were well done, easy to follow and understand. Its also pretty easy to go back and find particular things I want to review before some project I was working on. Overall it was good value for the cost.
