We are passionate about technical systems on boats since the 1970s (at least one of us) and we have a mission:
We offer the internet's most profound knowledge on
boat mechanics and electrics.

By now, over 2,500 students from 85 different countries have taken one of our courses.
We currently offer two courses on marine electrical systems: Boat Electrics 101, covering marine DC systems and Advanced Marine Electrics, covering a large variety of advanced topics. And we are very proud of the most recent addition to our course program: our brand new Marine Diesel Engine Maintenance Course!

... adding the BoatHowTo content really helps our school produce a higher level technician entering the field.
The overwhelming responses from our students were very positive. Adding the BoatHowTo content to our electrical curriculum really helped us get the students a leg up on understanding the core concepts of marine electrical. I feel it especially helped our younger students learn the material in a way that was more familiar to them. The way I used the modules was to assign them as homework before discussing the same topics in our classroom lectures. I noticed an increase in the comprehension of the topics and had less questions from the class during lectures which I would take as a good thing! I feel confident that adding the BoatHowTo content really helps our school produce a higher level technician entering the field.
Thanks for all your hard work and creating such great content!

What students say about us
I now understand all the electrical systems and how everything works together.
I want to let you know how impressed I was with the BoatHowTo course!!
From the very basics, through creating a detailed circuit diagrams of the electrical systems on my boat, my knowledge is years ahead of where I thought it would be at this point.
Thanks for a wonderful, extremely useful (and fun) course that takes a lot of the mystery out of sailboat electrical systems!!
Learning with you in 2022 has been a highlight of the year for me
I'm so thankful for you guys and all the hard work you put into sharing your knowledge with us. Learning with you in 2022 has been a highlight of the year for me.
An evolving learning platform
Having access to up-to-date materials on Boat Electrics is very handy for someone who deals with small boat design, like me. The best part of the whole course is that it actually isn't only a course, but it is an evolving learning platform.
