RYA marine diesel course Maintain, diagnose, repair

“The first priority is to know how to maintain your engine to stop you from getting into difficulties. If and when problems do occur, you need to make sure you know how to diagnose them and fix them. Going beyond the RYA syllabus makes this a very useful course”.
Dominic Walters – Master Mariner (Retd)


It doesn’t matter how well you maintain your boat or how good a sailor you are, eventually you are going to have an electrical failure. These are often minor, but unless you have the basic knowledge and skills to analyse and fix the problem, the whole boat can be disabled. The essential skills are not difficult to learn – you just need someone to show you how. We give you those skills in this RYA Course.  

Thrive with the Rubicon 3 10:2 teaching method

Rubicon 3 matches our expedition sailing expertise with advanced teaching methods. Every topic is broken down into ten minutes of really rich teaching input and deep content. Students are then given 2 minutes to digest the content and discuss it with a fellow student or write notes individually. Especially for complex topics, these short, sharp segments prove to be a transformational approach to learning. Read more about our approach below.

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.
