Every aspect of Modern Sailing - training, syllabus, course materials, quality of the boats, quality of the instructors, and the very friendly and helpful staff - exceeded my expectations. Modern Sailing has a first class sailing program in an environment with challenging winds and currents. I look forward to coming back to charter a boat and certainly plan to continue my sailing training.

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!

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!

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 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.
