RYA Yachtmaster Ocean Online Theory Course 

The ultimate backup is a sextant, accurate timepiece, nautical almanac and a set of, what are known as "sight reduction tables".

 

However whilst the process of translating a sextant sight into a position line is straightforward it is quite challenging to get to grips with. 

 

Unlike classroom training, where time is limited and students progress at different rates, online learning allows you to participate in lessons as many times as you wish. rewind and replay.

 

You can also repeat exercises and, if you struggle to get to the correct answer, we'll guide you through step-by-step.


On the course we will cover. 

  • The earth and the celestial sphere - the basics

  • The sextant - how to set up and use your sextant

  • Measurement of time - how time is measured 

  • Noon Latitude Positions - how it all started 

  • Sun, star and other sights - how we did it when we have accurate time

  • Compass checking - using the sun

  • Great circle sailing - the best way to get there 

  • Meteorology - choosing the best time and weather for your passage 

  • Passage planning - putting your ocean passage together 

  • Communications - keeping in touch and getting weather information

 

 At the end of the course, you'll be set an exam and, if you pass,  we'll issue you with an RYA/MCA Yachtmaster Ocean course completion certificate.
