The RYA shorebased navigation and seamanship theory courses are designed to help you unravel the mysteries of navigation, pilotage, passage planning and meteorology. They are great as stand alone courses, but also complement the various practical training courses.  Whether you are a sailor or a motor boater, the RYA shorebased courses equip beginning and experienced skippers and crew members with enough theoretical knowledge to go afloat and take charge of a yacht.

There are various ways to complete these courses: through multiple weekend classes, an intensive course during one week, or by distance learning. 

C-MASTERS complements the RYA courses with its own unique remote instructor support service, giving you access to one of our instructors for advice and answers to all of your questions. Not only during the duration of course, but up to a total of 6 months after finishing your course. Your instructor is at your service !

RYA books and course material

We are convinced about the superior quality of the RYA course materials. Without doubt the RYA handbooks and training packages are the best study materials for learning the navigation and seamanship skills, whether you are a beginning crew member or an experienced skipper, for sailing and motor cruising. 

For this reason, we have decided to provide a set of extra RYA handbooks with the standard RYA course material.

We will use the handbooks during your course. Afterwards they provide for an excellent reference book for when you're putting your theoretical knowledge in practice on the water.
