IBEX 365 Education

Basics of DC Energy System Design

This seminar was presented at IBEX 2021 as part of the Education Conference Seminar Series. The full seminar is now available in recorded format for $65/person.

An unacceptably high number of electrical problems on boats can be traced back to systems that are poorly designed from an energy assessment and delivery perspective. Perhaps the most obvious symptom is the high rate of premature battery death on boats. In this seminar intended to build core skills for boat builders and service yard staff, participants will learn how to determine basic DC energy needs and then ensure that they are met within the constraints of the unique operating profile of any boat.

Price: $65/ per person

Nigel Calder got into motorcycles and sailing dinghies as a teenager and has never been far from mechanical things and boats ever since. He and his wife, Terrie, built and lived on various canal and sail boats, including a Malo 45 that sported experimental electrical and propulsion systems. It was used for extensive testing of hybrid propulsion systems which, in recent years, morphed into a multi-year development of advanced generator technology now sold under the Integrel brand name.

Nigel and Terrie have sailed in the North Sea, the Atlantic from Faroe Islands to Portugal, the U.S. east coast, the Bahamas, and extensively in the Caribbean.

Nigel 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 and How to Read a Nautical Chart. He recently released a memoir of his family’s first long cruise titled Shakedown Cruise.
