Sailing Navigation Courses — OSS 105

Piloting and Electronic Aides


During an Offshore Sailing School Coastal Navigation course (OSS 105) you learn electronic navigation with emphasis on back-up piloting, using traditional navigation aids. You may think with GPS, chart plotters, and other electronic aids you don’t need to know the theory and techniques of piloting with charts and the stars. When batteries die and electricity fails on your boat, you always should have a back-up, and that’s what you will learn in our comprehensive sailing navigation courses. Join a boat navigation course below and get in touch if you have any questions.

“You get a lot out of these courses because of the depth of experience of the instructors. My Coastal Navigation instructor had circumnavigated the globe in a round-the-world regatta. You can’t ask for more experience than that.”
