This 2-day class is designed for both recreational boaters and professional mariners looking for a better understanding of marine electrical systems as well as practical skills such as troubleshooting and installing simple circuitry. The electrical systems class covers basic electrical theory, system design, maintenance, and basic troubleshooting and repair skills. Students receive both lecture and hands-on instruction utilizing multimeters and electrical circuitry developed for the course.

Upon completion of this course, students are able to understand basic electrical theory, DC system design, troubleshoot simple electrical failures, and create basic circuitry for DC installations. Although the course is not designed to turn boat owners into marine electricians, graduates have the confidence to troubleshoot basic electrical problems. They will also know when an electrician is needed, and are better equipped to communicate with industry professionals.
