ASA 107, Celestial Navigation | Modern Sailing

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.

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.

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.

Testimonials

  • John Kipping

    The meeting room was quite adequate and the location most convenient, but the course outline and instruction were outstanding. Modern Sailing is fortunate to have such a well organized instructor in Mr. Stan Lander who teaches very well from a rich professional background. Mr. Lander was generous with his time and patiently in helping students who needed more attention or time in understanding various aspects of the curriculum.

  • Danny Collins

    The office staff was very accommodating in meeting my availability.

  • Emma & George Stubbs, Sausalito

    We just took our ASA 106 at a school in Rhode Island as we prepare for 6 months of cruising in the Caribbean. The class was great, but more than anything it made us really appreciate the quality of teaching and rigor at Modern Sailing. Even though we were the newest to sailing, the group seemed to think that we had the best fundamentals. We felt very well prepared and we see why Modern Sailing has the reputation it does.
