RYA Yachtmaster Ocean Theory

The RYA Yachtmaster Ocean Theory course is the initial step towards achieving the RYA/MCA Yachtmaster Ocean Certificate of Competence. It caters for those interested in blue water cruising or traditional navigation. The course provides essential theory skills for undertaking an ocean passage as a mate or skipper, focusing on astro-navigation and worldwide meteorology. It teaches the use of the sextant for position fixing and compass checks. 

In addition to astro-navigation, the course covers passage planning, sea communications, routing charts, pilot books and modern technological tools for ocean routing and weather prediction, such as computer programmes and satellite/radio broadcasts.

 Crew management, watchkeeping, provisioning, water and fuel management, and emergency equipment are also addressed.
