VI Education

Do you have a sextant but don’t know how to use it?  Do you know want to know what MERPASS is? Do you want to learn more about Celestial Navigation?  Would you like to have a back-up navigation system you can use if your GPS stops working? Then this is the course for you.

The Vancouver Island Chapter is pleased to offer a one day, in person course on the basic Theory and Practice of the Sextant including calculating latitude and longitude from a noon sight, instructed by Scott Crawshaw.  Knowledge of the theory and use of the sextant provides an excellent foundation skill for all offshore sailors and can provide a trustworthy navigation tool when modern systems fail for whatever reason.

The course consists of theory in the morning followed by a practical session at Saxe Point in the early afternoon.
