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

    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!

    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!

  • 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.

  • John Boynton

    The class was terrific. I know you must get many compliments about your sailing instructors...But I must tell you that Robert is outstanding. Having taught SCUBA, I really appreciate the way he is so sensitive to all on board, dealing with each so well, knowing quickly their strengths and weaknesses making each feel special and cared for.

    The vessel was clean and in fine condition - very nice boat for training, well-equipped.
