4 The result of the project, which was accomplished primarily inside a giant seaplane hanger at the old Alameda Naval Air Station, is a vessel poised for another 111-year Thayer received regular maintenance during her years with the State and National park systems, but her basic structural timbers were all original, 1895 material. Although massively-built, of tight-grained Douglas fir timber, vessels of this type were designed for a working life of perhaps twenty years. By the mid-1990s, Thayer s framing timbers were soft with dry-rot. The rebuild process began in December of 2003, when the Thayer was towed to the Bay Ship and Yacht Yard in Alameda, Califor-nia.

5 Following removal of her masts and deck machinery (such as capstans and winches), the vessel was hauled onto a floating dry dock and supported in a massive steel cradle. House-moving dollies shifted the cradle aboard a barge, and tugboats towed the barge to the old Naval Air Station. There, deckhands carefully rolled Thayer ashore and into the huge seaplane a high-tech laser-scan to determine its shape, workers carefully dismantled the vessel s hull, stripping off the outer plank-ing by hand to expose the rotted frames or ribs underneath. Piece by piece, over many months, the individual timbers were replaced using Douglas fir.

6 The major centerline timbers of the bow and stern were replaced, as well as the heavy deck beams. The original L -shaped knees, were refurbished and reinstalled, support-ing the main deck beams. Shipwrights laid down a new deck, of 4 square planks, in 40-foot lengths, and caulked it tight. Although structurally sound and watertight once more, Thayer s rehabilitation work will continue at Hyde Street Pier for a number of years. Ongoing projects will include installation of Interior fittings, completion of the forward deck house, and restoration of her sailing C. A.

Photo taken in early 2006 shows the hull fully planked and caulked;Inside the hold of the ship. The white, l-shaped pieces are called knees. A knee is produced from the part of the Douglas fir tree where the root connects to the trunk, taking advantage of the natural shape and strength. The knees support the main deck beams and connect the hull to the deck above. The pieces of wood between the knees, attached to the hull, are temporary supports called cross spawls.

8 They were installed to help hold the shape of the hull during construction; Workers caulking the hull by driving oakum, tarred hemp fiber, into the seams between the hull planks. Caulking is a fine art. The right amount of oakum must be driven between the planks with the right amount of pressure to ensure a watertight hull; Workers pay the main deck seams with hot marine glue, one of the final steps in caulking the deck. Caulking stiffens up the deck and makes it watertight;A recent photo shot from the main deck looking toward the fore hatch and bow. The white outer structures are the bulwarks, coated with a white primer.
