Andrea Geisinger

Instructor

Andrea is a professional mariner, offshore sailor, cruiser, captain, and instructor with more than 30 years of experience. Her sailing journey began on Lake Neuchâtel in Switzerland and has taken her through European waters, San Francisco Bay, the West Coast, Alaska, and the South Pacific.

She has completed four Pacific crossings, participated in the Pacific Cup, cruised extensively in French Polynesia and Fiji. Her professional experience includes serving as captain and crew aboard high-speed ferries, luxury yachts, charter boats, and private vessels, as well as working as a boat captain and wilderness guide in Alaska.

As an instructor, Andrea draws on decades of real-world experience to make sailing practical, understandable, and less intimidating. She emphasizes strong fundamentals, situational awareness, sound judgment, and understanding the reason behind each decision.

Andrea enjoys helping beginners build a solid foundation and experienced sailors refine their seamanship, boat handling, confidence, and decision-making. Her teaching is thorough, calm, and encouraging, with the goal of helping students think independently rather than simply memorize steps.

She holds a USCG Master 200 GRT Inland License, a USCG Mate 200 GRT Near Coastal License, ASA instructor qualifications through ASA 108 Offshore Passage Making, and ABA Powerboating instructor qualifications.

Andrea wants every student to leave the boat with stronger skills, greater awareness, better judgment, and the confidence to take responsibility at the helm.

As a crew member on an epic sailing adventure from San Francisco to Hawaii to Alaska, Andrea appeared in the pages of Latitude 38! See pages 62 to 65 of the January 2023 issue.

When Andrea isn’t teaching or captaining, you’ll find her happiest on the water, capturing stunning sailing scenes from San Francisco Bay and beyond. Follow her adventures on Instagram and join her for an unforgettable learning experience on the waves!

    I love sailing in the San Francisco Bay and greatly appreciate everything that MSC has to offer, the classes, clinics, club sails, racing and charters. I enjoy our supportive sailing community and use every opportunity to spend time on the water. After obtaining the certifications from MSC I did my first charter in Croatia in 2022 with my family. It was amazing and we’re looking forward to returning soon!

    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.

    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.

    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!

    The Full Moon Sail with Skipper Bob Gutsgell was Ah-Mayzing!! The group dynamic was lovely and the views spectacular. I can't say enough good things about the experience. Thanks so much for the wonderful Club Sails, they are really great.
