Situated so close to the San Francisco Bay, it's no wonder Marin residents have a passionate interest in aquatic experiences. Marin Power & Sail Squadron seeks to nurture that passion and help it develop, offering classes in sailing, scuba and yachting. For reasonable class fees, individuals can become fully certified in the art of scuba diving. Students can also learn to steer a small schooner under the Golden Gate Bridge. Class sizes are limited and costs vary seasonally.
