Purpose & Benefits of Course

In this course you will explore the best options for preparing your boat's electrical systems for offshore. What do you need to consider for batteries, charging, and power management overall when you are offshore?

You will learn about the key electrical components, circuits and discuss electrical problems using a multi meter. The goal is to work towards electrical system's self-sufficiency while offshore.

(This course is held on a Saturday so that it is a good option for those who cannot attend the Friday course held by Nigel Calder later in the month.)
