Live Q&A
If properly installed and maintained, diesel engines are remarkably reliable - and almost all problems are self-inflicted due to neglect. Join us for this two-part series as we journey into the world of marine diesel engines. Delve into the nuances of proper maintenance and upkeep, both suitable and unsuitable for boat owners, and learn troubleshooting tips and tricks from our experts, Nigel Calder & Jan Athenstadt of, for navigating any unforeseen hurdles that may arise on and off the water.

We think it's important to share why we’re so passionate about teaching you what we've learned about sailing. See, we teach it because we live it. It wasn’t too long ago that we were trying to figure out how to chart our journey and set sail. We did all the research, watched the YouTube videos, and read thousands of articles and blog posts. Everyone was saying something different! It was overwhelming and made the decision to start our adventure even harder. Quite frankly, we were nearly terrified... But we didn't give up on our dream life. Through trial and error we found what works, and more importantly, what doesn’t work. Over the last few years, we’ve been able to help change thousands of people’s lives by sharing our experiences.

Diesel Engine Fundamentals


Who is this class for?

This course is for anyone wanting to gain a better understanding of a diesel engine (and who does not mind getting their hands a little dirty). While a basic familiarity with engine components and prior experience with fundamental tools may be beneficial, they are not a necessity for this online class.

What Will I Learn?

Learn how to save money and ensure engine reliability by keeping up with essential maintenance for marine diesel engines. Discover how to identify common problems and the symptoms associated with them while learning simple troubleshooting procedures and fixes that are within the capability of most boat owners. Finally, we will address systems and procedures that should be left to professional mechanics.


  • The critical importance of clean fuel
  • Oil changes with minimal mess
  • Raw and freshwater cooling system maintenance
  • Heat exchangers and sacrificial anodes
  • From air inlets to exhausts
  • Common problem symptoms
  • Simple troubleshooting procedures and fixes for many common problems


Nigel Calder

Nigel Calder and his wife, Terrie, have built or owned a succession of boats on which they have cruised extensively in the Caribbean, the U.S. and Europe with Pippin (now aged 38) and Paul (37) augmenting the crew along the way. In addition to serving many years as a diesel mechanic, for decades Nigel has experimented with advanced electrical and propulsion systems, with funding from the European Union, the UK government, and a large U.S. corporation. Nigel has partnered with OceanPlanet Energy in Bath, Maine, to continue development of advanced solar panels, alternators and controllers. Nigel is a thirty-year veteran of the American Boat and Yacht Council (ABYC) which writes the standards for recreational boat electrical systems. He is best known for his Boatowner’s Mechanical and Electrical Manual, now in its 4th edition, and his Marine Diesel Engines, in its 3rd edition.


In addition to hundreds of magazine articles, he has also authored a Cruising Guide to the Northwest Caribbean, Cuba: A Cruising Guide, Nigel Calder’s Cruising Handbook, How to Read a Nautical Chart, and a memoir of his family’s first long cruise titled Shakedown Cruise. His most recent venture is a partnership to provide detailed and accurate online marine technical education at Currently available are courses in Basic Marine Electrics (BE 101) and Advanced Marine Electrics. Soon to be released is a course on Diesel Engine Maintenance.

Jan Athenstadt

Jan co-founded with Nigel to share comprehensive knowledge about boat electrics and mechanics with a broader audience. Holding a PhD in computer science, Jan brings valuable expertise to this online class as a moderator. His experience as a full-time liveaboard and operator of an online boat supplies shop in Germany will add practical insights to the discussion.
