Marti McMahon Diamond is an innovative Yacht designer, builder and owner. Her vision is to create intimate special occasion experiences on the most elegant private Yachts for charter on the San Francisco Bay.

Marti’s fascination with boating began with a 21-foot family boat she helped to restore while living in Chicago. This led her to renovate many boats needing attention upgrading in size and making every vessel better than the last. When the family moved to the Bay Area her hobby combined with her love for entertaining and cooking gave birth to her dream of launching a business that would combine all her passions.

Over the years, Marti’s vision of a premier Yacht charter company did become a reality as she went on to acquire a fleet of four on San Francisco Bay. She designed and built two of her former fleet, the 130 passenger California Spirit and the 700 passenger San Francisco Spirit which was christened by Charlotte Schultz and became a memorable high point of Marti’s career.

She sold the California Spirit to Giants Enterprises a few years ago and proudly markets that vessel and her Diamond Seas with the Giants.  These vessels are the charter yachts of choice for discerning clients who expect the finest services and crew on the Bay with a personal touch of detail.
