Marine electrical course Know your yacht's electrical system

“Having a solid understanding of your boat’s electrical system is as important as knowing how to sail. You cannot just pretend it doesn’t exist and hope for the best. Proper seamanship demands that you learn at least the basics, and I highly recommend this course”
Richard Heston – Master 3000


The Rubicon 3 marine electrical course is a two day course aimed at boat owners and general sailors who want to be equipped with the knowledge and skills for a solid understanding of the DC (battery operated) systems on a yacht or boat. Developed through years of expeditions sailing and training of crew, these are essential skills when undertaking any maintenance or when at sea should faults occur. All crew, but especially skippers, ideally need to be able to conduct electrical troubleshooting

The instructors

Delivered by a hugely experienced marine engineer, and mixing theory and lots of hands-on practical training, this is acknowledged as one of the best courses a boat owner can take to gain the skills needed to maintain, diagnose and repair a vessel’s DC electrical systems.

Who is the course suitable for?

The course is suitable for total beginners, those with some existing or basic knowledge and of course boat owners. The instructor will start the students with the very basics and progress from there.

All teaching is in a classroom, led by an expert Rubicon 3 instructor. Class sizes are limited to 8 students, to ensure that you have proper levels of interaction with the instructor. Students come with all different levels of prior knowledge, but do not worry. The entire syllabus is taught from the beginning, and no knowledge of the syllabus is expected prior to starting

The simple truth is that shore based courses in the sailing industry are often taught by people who have done very little sailing outside of their local area. This hugely limits their skills and experience, beyond repeating the same anecdotes and lines lesson after lesson.

At Rubicon 3, we sail year round to some of the world’s most remote and challenging regions. We are constantly learning, evolving and improving our approach to sailing and navigation. When you learn with us, you will be getting expert instructors teaching the latest approaches to the theory.

If you have been listening for longer than 10 minutes, then it’s time to stop. Any longer than that and whatever is coming out of the instructor’s mouth isn’t going to be having much impact. You will increasingly switch off because it is simply too much new information. It needs to be processed, before more information can be digested.

“To keep students engaged, you must win the battle for their attention every 10 minutes”.

The idea of teaching in 10 minute segments is well recognised as the approach that works. It is variously known as‘Chunk and Chew’, ‘Turn and Talk’, ‘Stop and Jot’ and  ‘Listen-Stop-and-Write’.

It works like this:

  • The instructor breaks all the content down into manageable portions and then allows time for learners to digest the information.
  • Students receive 10 minutes of rich teaching and content (listening, watching, reading)
  • They are then given 2 minutes to digest & discuss the content with a fellow student or to write notes individually.

It is well recognised now that when information is delivered in chunks, we remember more and the 2 minutes given for chewing is vital for absorbing, processing, discussing and comprehending. The research shows that the key to mastery of new concepts is frequent and persistent review of material.

The two minute breathers ensure the brain has a break and can consciously and subconsciously replay the content. Taking a breather also allows students to generate questions.
