Why Navathome

We have chosen Navathome to provide the on-line training course for the RYA Day Skipper, Coastal Skipper / Yachtmaster, and Yachtmaster Ocean as we think they are the best on-line course provider out there. They are an RYA recognised training centre who quite simply specialise in online training.

The course is fully interactive, and works on PC's, Macs, iPads and tablets (note that the RYA's own plotter which is part of the course doesn't work on mobile devices but this is not an essential part of the course).

When you sign up for the course you have six months to complete it - which is normally plenty of time. If you wish to extend it then it and you have completed 80% of the modules we will pay for the extension (in the unlikely event you haven't got this far then there is a small admin fee to extend).

If you feel that you prefer face to face contact then contact us for details of our classroom courses.

Once you have signed up for the course we also give you a voucher off any Day Skipper, Coastal Skipper or Yachtmaster week on one of our sailing or motor yachts
