Passport Resorts of San Francisco has sold its remaining interest in Sea Ranch Lodge to Fillmore Capital Partners of San Francisco, which has been the majority owner for six years.

The sale price was not announced.

The lodge has 19 rooms, all facing the ocean, plus a restaurant, boutique and gallery. It is perched on 52 acres at Sea Ranch, a sprawling community of distinctively styled homes along a 12-mile stretch of the Pacific Ocean just south of Gualala.

In the past year, its owners have upgraded all guest rooms, the Black Point Grill restaurant and common areas, said Peter Heinemann, co-founder and managing director of Passport Resorts.

Fillmore Capital Partners, led by CEO Ronald Silva, develops and manages investments for institutional and private investors, focusing on health care, lodging and real estate assets.
