IBEX 365 Education

Correcting Critical Electrical Flaws and Failings

This seminar was presented at IBEX 2023 as part of the Education Conference Seminar Series. The full seminar is now available in recorded format for $25/person.

Do batteries last 5-10 years? Are all circuits properly overcurrent protected? Are through-hulls at risk of failing from galvanic corrosion? We explore several common failure modes and potentially unsafe installation errors and omissions, including some routinely seen on new boats straight from the boatbuilder. Builders will take away a list of errors to eliminate from their boats, and service technicians a tally of weaknesses to look out for in the vessels they care for.

Price: $25/ 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.
