It was built around 1910 (the form also gives c. 1913) by Brock Schreiber.","why_significant":"The nomination presents the boathouse as the social and recreational hub of the small resort community of Inverness for about 30 years. It served vacationers with boat lockers, launches for hire, and a children's beach. It is described as a rare surviving structure of early maritime and recreational activity on Tomales Bay that has kept its original character.","narrative":"Brock's Boathouse is a gable-roofed redwood building, measuring 34 by 60 feet, that sits over the water of Tomales Bay in Inverness, California. Brock Schreiber built it around 1910, and a 300-foot wharf once led out to it. For roughly three decades it was the center of social life in the small resort town, renting lockers and berths, offering fishing gear, a winch and boat ramp, and running launches that carried vacationers around the bay. Children's Beach at the foot of the wharf is still used by new generations of children. Only 78 feet of the wharf remain, and the ribs of one launch, The Queen, lie in the sand. The original wooden uprights had rotted, so volunteers poured a new concrete foundation in 1975-76, paid for with privately raised funds. The building has changed little in appearance, and it was listed as a surviving reminder of early recreation and boating on the bay.","period_of_significance":"1900-","architect_builder":"Brock Schreiber","architectural_style":null,"criteria":[],"status_note":"Condition is fair. A new concrete foundation was poured in 1975-76 by volunteers, the wharf and ways are deteriorating, and the roof needs replacement.
