ASA 107, Celestial Navigation

6 evenings, Tues / Wed / Thurs

Since ancient times, human beings have looked to the heavens to find our way around on Earth. It was only a few hundred years ago that we developed systems to plot latitude and longitude fixes based on the positions of celestial bodies, and the common practice of celestial navigation by means of a sextant emerged. The basic premise of celestial navigation relies on calculating angles between the observer, the horizon, and a predictable celestial body such as the sun, moon, or visible planets and stars.

In the modern age, we’ve become dependent on highly precise and user-friendly navigation technology - but technology can fail – and then what? For safety and self-sufficiency, celestial navigation remains an essential skill for every ocean-going mariner.

If you have ever dreamed of sailing into the horizon, take ASA 107, Celestial Navigation with Modern Sailing School & Club. Have confidence that no matter how far from shore you sail, you will always be able to find your way.

With the ASA 107 course, you will learn to:
• apply celestial navigation theory and practices for safe navigation of a sailing vessel in offshore waters;
• use the sextant to determine your vessel position by the Local Apparent Noon method; and
• deduce your location with sun, moon, planet and star lines of position and fixes.

We expect this course to fill quickly. If you are prompted to join to the waitlist, please do! Waitlists help us track demand - we'll add more courses to our schedule accordingly.

  • Steve Hood, Basic Coastal Cruising

    I would definitely recommend Modern Sailing to anyone who is interested in learning to sail the right way.

  • Mike, Santa Rosa, California

    All of the courses and my instructors (JT and Stan) were extremely professional and full of knowledge and experience. I found I was able to learn from their experiences beyond the scope of the courses, and look forward to future opportunities to do so. I would highly recommend Modern Sailing to anyone.

  • Esther C

    I took ASA 101 with them recently. They have the best customer service I've ever seen! I mistyped my address when I signed up online so didn't receive the textbook. I called and the lady immediately sent me another copy! Everyone at the club is super friendly.
