No, we're not humble about it. The two-day TrawlerFest seminar "Everything You Need To Know About Diesel Engines" is one of the best preparatory courses of its kind anywhere. The instructors, author Nigel Calder and boatyard owner Steve Zimmerman, are knowledgeable, articulate and bring a welcome sense of humor to their presentations.

The next TrawlerFest is in Stuart, Florida, in March, followed by Bremerton, Washington, in May. The classes are limited to 36 students and usually sell out. Visit

But not everyone has the wherewithall to fly from whereever they live to attend.

We have a solution for you. It's a good solution, albeit a partial one. Boaters University, operated by our parent company, offers an online class called "Marine Diesel Maintenance & Troubleshooting," taught by none other than Steve Zimmerman with help from our TrawlerFest partners at Whiticar Boatworks of Stuart, Florida.

Let Steve tell you what it's all about.
