Sausalito is a city in Marin County, 8 miles south-southeast of San Rafael, set on steep, wooded hillside and shoreline tidal flats, with Richardson Bay and Pine Point among its prominent features. The name comes from the Spanish sauzalito, meaning small willow grove, and the city was incorporated on September 4, 1893. The rig crosses the valley from the foothills for repairs and fabrication at homes, docks, shops and jobsites across Sausalito.

The Rancho Saucelito had been granted to William Richardson in 1838, and in the 1870s the North Pacific Coast Railroad extended its tracks south to a new terminus in Sausalito, where a rail yard and ferry to San Francisco were set up. Sausalito has a long history of boatbuilding, and the Spaulding Boatworks, founded in 1951 by Myron Spaulding, has been in continuous operation since. Boat trailers, ladder racks and shop carts get repaired right where they sit, because the rig carries engine-drive welding power, wire feeders, an oxy-acetylene torch and a plasma cutter.
For directions, a landmark helps: Bridgeway, the Sausalito Ferry Terminal, Dunphy Park, or the houseboat community at the north end of town.
Yes. The Sausalito houseboat community has more than 400 houseboats along the north end of town, about two miles from downtown, and the 2020 census counted 7,269 residents. US 101 brings the rig down from Mill Valley. Call or text and we'll set a time.
Yes. A corroded trailer keel roller bracket, a bent truck ladder rack, a broken outboard motor stand and a split cargo trailer door hinge get welded right where they're parked. Send a photo and the address and we'll plan the trip.
Yes. Sausalito sits 1.5 miles southeast of Marin City, and the Robin Williams Tunnel on US 101 connects the two at the highest point of the Waldo Grade.
