This course assumes that you already have knowledge equivalent to the Coastal Skipper / Yachtmaster Offshore shorebased course when you start it. You do not need any prior knowledge of astro navigation.It requires approximately five days teaching plus time for coursework and exams.This is a very interesting and advanced course covering astro navigation, global meteorology and passage planning: •Astro navigation starts with the basics - global time and usage of a sextant. We follow this by working on sun and star sights. Moon and planet sights and compass checking complete this part of the course. •Meteorology extends your weather knowledge by looking at global wind, weather and ocean currents and how they vary over a year. We start with a review of the world's weather systems to help you understand WHY the winds and currents work in the way that they do. A key part of this topic covers Tropical Revolving Storms - how they form and how we can best take avoiding action. •Passage planning is an interesting part of the course which covers factors such as ocean routing, passage planning on the ocean scale and how to make an ocean passage. During the course you will work on 14 coursework exercises and sit one exam. On successful completion of the course you will be awarded the RYA Yachtmaster Ocean Shorebased Certificate.Our cost includes all handouts, marking and student support by phone and email.See our Terms and conditions and course price pages for more information.
