Thayer is one of only two West Coast lumber schooners left in existence. She was built to haul fir lumber from the Pacific Northwest to the expanding towns and cities of California. Thayer later served the American cod and salmon fisheries of Alaska, helping to feed a growing country.
As Thayer neared her 100th year, she was disintegrating rapidly, and drooping at the bow and stern. In planning to save the Thayer, park staff considered whether to put her ashore inside a building. The park decided that rebuilding her using traditional materials and keeping her afloat, was the only practical and acceptable choice. Congress authorized the project in 2002.

In 2003 Thayer was taken out of the water and put onto dry land. She creates an eerie pre-dawn sight. After being towed into the Alameda Estuary, she was lifted by a drydock and rolled onto the tarmac of the old Alameda Naval Air Station. The former seaplane hangar made an ideal workshop for the restoration project. |

The ravages of dry rot are evident in the massive frame timbers and planking. |

A Mix of Old and New
As the vessel was taken apart, tons of rotten timbers were discarded, but every piece that could be salvaged was reused.
The park was fortunate to have the Bay Ship and Yacht Company just across the San Francisco Bay in Alameda. This firm offered the rare skills and experience needed to do the job. They finished the hull and deck using only original style timber and fastenings.

Lumber Schooner C. A. THAYER (9 Photos)
Restoration Project 2003-2007
|
After a major restoration of more than three years, the National Historic Landmark C.A. Thayer returns home to San Francisco Maritime National Historical Park in April 2007. The magnitude and extent of this restoration is virtually unprecedented in the history of modern maritime preservation, ensuring that this 156-foot long wooden schooner can survive for another hundred years.
“This project has been a labor of love for all of us who were privileged to be involved,” said San Francisco Maritime National Historical Park Superintendent Kate Richardson. “On a practical level, we have preserved a vital piece of American history and culture. On an emotional level, we have breathed life back into the hopes and dreams of the men and women who lived on, for, and by the sea. Thayer is a legacy of opportunity and independence that I am proud to pass along to future generations.”
The C.A. Thayer is now structurally sound and watertight. Additional restoration work will continue at Hyde Street Pier for a number of years, with the goal of preparing Thayer to sail once again. Ongoing projects will include restoration of her sailing rig, completion of the forward deckhouse, and installation of interior fittings.
