The RYA Yachtmaster online theory course is an advanced  course that builds on the knowledge gained on the shorebased Day Skipper course. The course is aimed at sailors and motor boaters who are looking to undertake more complex passages, perhaps offshore or at night. This course is a must for those looking to work towards taking the RYA Coastal Skipper or Yachtmaster Offshore practical exams.

The RYA Online Yachtmaster course costs £315.00 and includes the RYA Course pack which contains: 2 Full size Training charts, a Training Almanac and Shorbased notes that will act as an Aide-mémoire throught the online course

***NEW*** When you purchase this course you will also gain full access to our new Online Diesel Engine course.

The Yachtmaster online course is an intensive programme covering advanced navigation techniques. It includes position fixing, course shaping and plotting, tidal knowledge, secondary port calculations, navigation in restricted visibility, Admiralty publications and electronic position finding equipment.

The meteorology tuition within the course includes the taking and interpretation of forecasts, plotting of weather systems and weather prediction. Students are shown how to use this information when planning and executing passage plans. The International Regulations for Prevention of Collision at Sea are dealt with in detail and you will also learn more about yacht stability and safety offshore.

Students will need to have a valid RYA Day Skipper theory certificate or equivalent and have thoroughly revised the Collision Regulations before taking the course.

The animated lessons are not matched in any other Yachtmaster online course. They are designed to make learning interesting and questions easy.

Assessment methods within the courses ensure student training is Evaluated, Validated and Recorded.

The majority of Yachtmaster Online courses are mainly narrated videos and slideshows and to be honest, you may as well buy a book.

Our Yachtmaster online courses are fully animated lessons with an optional voice over so you get the best of everything.
