Mark Showalter

Chief Operating Officer (COO)

Mark has been sailing on San Francisco Bay for decades, starting as crew in beer can races out of Berkeley. For many years, he also sailed his Laser on the Bay, and has since decided that he prefers big sailboats.

In 2019, Mark was a member of the crew dubbed “Kings of the Beer Cans” by Latitude 38.

Mark’s sailing adventures have taken him beyond the Bay to Catalina, the British Virgin Islands, and Croatia. He’s now looking forward to his next international sailing adventure, but doesn’t know when or where that will be.

“I’m excited to take on this new role,” Mark says. “I encourage everyone to come by, say hi, introduce themselves, and let me know how we can take the Berkeley school to the next level.”

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.

I took ASA 101 with them recently. They have the best customer service I've ever seen! I mistyped my address when I signed up online so didn't receive the textbook. I called and the lady immediately sent me another copy! Everyone at the club is super friendly.

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

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.

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!
