4 minutes readIn this article in series about RYA certifications we reveal what is covered by the Yachtmaster Offshore Shorebased Theory course.
RYA Yachtmaster Offshore Shorebased Theory course is an advanced 6 days training in navigation and meteorology for candidates for the Coastal Skipper and Yachtmaster Certificates.
It is recommended to take the RYA Yachtmaster Theory course before the practical exams, especially if you have not sat at the chart table for a while. Holding the RYA Yachtmaster Theory is also required if your long-term goal is to become the Officer of the Watch 3000GT.
Syllabus
The Yachtmaster theory course provides instruction in tides and tidal streams, pilotage, meteorology, safety at sea, passage planning and advanced navigation techniques including yacht positioning, use of a magnetic compass, GPS and chart plotters.
1. Position
