Boat Electric Systems (Design & Installation)
Boat Electric Systems (Design & Install)

Who is this course for?
This course is aimed at those who are looking to get an understanding of a wide range of boat electrical systems, perhaps in advance of a complete sail-away fit-out, or a refit of their existing onboard systems. The course requires no previous electrical knowledge, so is ideal whatever your level of experience.
By the end of the two days, you’ll have a great understanding of electrical systems and confidently be able to design, install and troubleshoot your onboard electrics.
What does the course involve?
In a mixture of classroom and workshop sessions, you’ll get a very practical introduction to the design, materials, tools and techniques of boat electrical work. It’s a hands-on course, so in conjunction with some of the theory that you’ll learn, you’ll be ’on the tools’ designing, making, connecting and testing various electrical systems.
As you’ll see below, the course covers a wide range of topics and systems – and even if you don’t understand all these terms yet, you will by the end of your course!
The course will cover the following topics:
- RCD and BSS requirements
- Basic electrical theory, volts, amps, watts and resistance.
- Calculation of voltage drop and wire sizes.
- Comparison of 12 and 24v systems
- 12 / 24v Domestic Circuit design, breakers, fuses, lighting, pumps
- 12 / 24v Engine room design, cable sizing, battery types and sizes, split charging.
- 240v Circuit Design
- Cable termination and labelling
- Battery Selection and installation
- Alternate energy sources, Solar, Wind, Generators and travel packs. Selection and installation.
- Selection and installation of Inverters, chargers and Combi’s
- Practical circuit installation including lighting, pumps, 240v, combis and solar panels
- Testing and fault finding
- Information and control systems Masterbus and VEbus
- Generators, selection and installation
- Split charging, multiple alternators
- Hybrid Systems
- WiFi & communications
As well as these subjects, and if time permits, other subjects can be covered by request.
