Calder & Zimmerman Reprise 'Everything To Know About Diesels'


Our tremendously successful two-day engine seminar with Nigel Calder and Steve Zimmerman will be repeated at TrawlerFest-Bay Bridge Marina on Sept. 27-28 with its unique mix of classroom instruction and hands-on training. The seminar is entitled “Everything You Need To Know About Diesel Engines.”

 Nigel Calder leads the class in a segment on electrical system troubleshooting.

Well known as an author, Calder is PassageMaker’s technical editor, and Zimmerman writes the magazine’s “Troubleshooter” column. Both men are real-deal cruisers.

Calder is author of six books, including Boatowner’s Mechanical and Electrical Manual, Marine Diesel Engines, Refrigeration for Pleasureboats, The Cruising Guide to the Northwest Caribbean, and Cuba: A Cruising Guide. Zimmerman, a long-time friend of the magazine, is president of Zimmerman Marine, which operates four boatyards, in Maryland, Virginia, and North Carolina, specializing in repairs, refits and maintenance. He has been repairing and building boats for almost four decades.

Calder himself will lead attendees in electrical troubleshooting using multimeters and training aids that he has developed especially for the class. The program will conclude with a panel discussion and questions from the audience.


Feedback from past Diesel Engine attendees was overwhelmingly positive with this from one of them:

“Nigel was excellent I believe he presented a great deal of information but did not drown us in the unimportant stuff. His presentation seemed to get at the ‘meat’ of the issue directly. Thus, he was able to cover more. He was entertaining and repeated: ‘You can do this’ many times which I found very supportive.

“Steve, your presentation was equally solid. I liked your approach from the prop forward and it was great to hear what shipyards see as the major problems.”

The class is limited to 36 attendees and has almost always sold out.

Most PassageMaker fans know that TrawlerFest is more than a seminar series. The event’s in-water boat show, runs Thursday, Sept. 29 – Saturday, Oct. 1 . Dozens of power cruisers will be open for inspection on the docks and vendors will be on hand to demonstrate products and services.
