RYA Ocean Yachtmaster Theory Online

Why you should choose this course?

The RYA Ocean Yachtmaster™ Theory Online is for those who have a passion for sailing and navigation. It is a wonderful course that will keep you occupied for hours on end. It is not just about finding position from stars and planets, it covers weather, passage planning, watch keeping and much more.

This course is delivered by Navathome, an RYA Recognised Training Centre specialising in online training.

You can book your RYA Ocean Yachtmaster™ theory course online and be working straight away on the sections where the RYA pack is not needed. Your RYA pack, containing your combined almanac and questions will be posted first class post the same day.

Why you should choose this course

This is a question where we can say there is no other choice. Our RYA Ocean Yachtmaster™ theory course is by far the best Astro Navigation course around and beats not only other distance learning courses but classroom courses as well. All the usual pictures that are normally provided as still slides, are fully animated in our course providing a learning opportunity not to be missed.

If you are interested in this fascinating subject then our course with its animated graphics will help you understand how it actually works.

That is why we have devoted so much time to making this course fully animated and tried to make the subject more understandable. From the feedback we have received, the 100% pass rate and the high marks of the students that have completed the course, I think we have achieved this.

The lessons are designed to not only give you the ability to fill in a few forms but to understand what you are filling in and why.

Even the answers that you have submitted to your instructor are provided with instant feedback.

Add to this the personal help you will get from the Navathome team, and you have a package that cannot be matched. Our prices are very competitive given the quality of the courses, the feedback we give and the friendly repartee we build up with our students. We will spend whatever time is needed to make sure that you achieve your aims.

This is followed by helpful, friendly and personal feedback from us based on the answer that has been submitted.
