We offer the internet's most profound knowledge on
boat mechanics and electrics.

By now, over 1000 students have taken our first two courses on marine electrical systems: Boat Electrics 101, covering marine DC systems and Advanced Marine Electrics, covering a large variety of advanced topics.
We received more positive feedback than we could ever have imagined! This motivates us even more to keep working on great courses, articles and videos. Our next project will be a course on Marine Diesel Engines.
