RYA Yachtmaster Ocean Course


Unravel the mysteries of astro navigation, using a sextant, ocean passage making, worldwide meteorology and electronic navigation aids.

This course is for those aspiring to blue water cruising and is ideal for holders of the Yachtmaster Offshore certificate who are preparing for their first ocean passage. If you are working towards your Yachtmaster Ocean Certificate of Competence, completion of this shorebased course exempts you from the written exam.

Prior to the course your navigation skills should be at the standard of the Coastal Skipper/Yachtmaster Offshore shorebased course.

Topics covered include:

  • The earth and the celestial sphere
  • Practical guide to use and care of sextant at sea
  • Meridian altitudes
  • Sun, star and other sights
  • Ocean passage planning

Classes are held at West Mersea Yacht Club in convivial surroundings and in a relaxed manner, we believe our students benefit from the opportunity to discuss and learn in this environment.
