Course Reviews

Nigel Andrews

Helped me master it

This was my third attempt at an RYA Yachtmaster Ocean online course from different companies, and by far the best. For an admittedly difficult subject matter to get one’s head around, the instructor presents a very organized and understandable series of lessons that combine learning with wisdom and humour. Its still a tough subject, but this course helped me master it. Thanks!

Mathew Myatt

Ability to repeat when in doubt

Logical and clear. What was really good was the ability to go back and repeat or all or part of a lesson to ensure you truly understand a concept / principle, something which is more difficult to do when in a real classroom situation

David McIntyre

An excellent course

I found this course to be very comprehensive and informative. The format was very well presented and clear. The main advantage for me was the convenience of doing this in your own time. They are very generous with this. All my correspondence was very promptly replied. They are certainly very on the ball. The instructors gave clear and prompt feedback.

David Collins

Well worth the investment. Excellent!

A challenging course which stretches you but backed up with excellent coaching and instructor support. Worth the investment in time and money. Highly recommended.
