Embark on a journey to learn the age-old techniques of celestial navigation, a fundamental skill that connects mariners to the vastness of the cosmos and the traditions of seafaring.

ASA 107, Celestial Navigation

6 evenings, Tues / Wed / Thurs
- Sausalito

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.

ASA 118, Docking Endorsement

Modern Sailing offers the American Sailing Association's docking endorsement, ASA 118
One Day, 9am - 4:30pm

The winds and tidal currents of San Francisco Bay can be challenging to sailors not only when sailing out on the bay, but especially when maneuvering in and out of dock slips. Join us for this one-day course in which you will learn strategies and techniques to safely and efficiently dock a 30' - 32' auxiliary-powered sailboat in a variety of conditions. Hands-on practice will increase your overall boat handling confidence while you gain knowledge of basic auxiliary power theory, engine and steering controls, proper use of dock lines, crew communication, and safety.

    I would like to compliment Stan Lander for his coaching, counseling and teaching Heavy Weather Offshore Sailing. Stan was very accommodating to all of the student's interests and shared his many years of insight on handling the boat in heavy seas. I would certainly recommend Stan and this course to sheltered waters sailors. My confidence in handling a boat of this size was certainly enhanced by the experience.

    Thumbs up to (Club Skipper) Geoff (Love) and his wife Laura. I went on my first Club Sail on Sunday, January 18, 2026. They were terrific!

  • Warren Leiden, Member

    I try to get out on the water every week: out the Gate, around Angel, up Raccoon - I love it all. After 18 years as a member of OCSC in Berkeley, I learned to sail the bigger boats at Modern by taking ASA 103 and 104. My ASA 104 instructor Dave Russell was terrific. Also, Captain Bill Moreland has been very generous in giving informal advice whenever I’ve asked him. Thanks to Bill, I no longer have any anxiety about docking!

  • Trudy Flores

    Captain Jeff Cathers is really cool. I had such a great time on the Farallones Day Trip. It was actually my very best day of 2020. Thank you so much for coordinating the trip.

    The office staff was very accommodating in meeting my availability.
