Ukiah BeginningsEureka was built in 1890, at Tiburon, California, for the San Francisco and North Pacific Railway. The ship was originally named Ukiah to commemorate San Francisco and North Pacific Railway’s recent rail extension into the city of Ukiah. A freight-car ferry, Ukiah was SF&NPR's "tracks across the Bay," ferrying trains from Sausalito to San Francisco.After WWI, Ukiah needed extensive repair, and shipwrights at the Southern Pacific yard labored for two years - eventually replacing all of her structure above the waterline. This kind of reconstruction was called "jacking up the whistle and sliding a new boat underneath."Re-christened Eureka, the vessel was launched from the Southern Pacific yard as a passenger and automobile ferry (her present form) in 1923. Steam Ferryboats on San Francisco BayThe Bay's first steam ferry (the tiny Sitka) arrived in 1847, stowed aboard a Russian cargo ship. But the ferry, Kangaroo, made the first regularly scheduled crossings in 1850. The Walking Beam EngineEureka's tall "walking beam" is the last working example of an engine-type once common on America's waterways. Manufactured by Fulton Iron Works of San Francisco, this engine remains unaltered to this day.Oil was burned in boilers to produce the steam, which drove a huge, vertical piston. Perched atop the engine, the walking beam changed this up-and-down motion into rotary motion via a connecting rod linked directly to the paddlewheel shaft. The twin paddlewheels (each twenty-seven feet in diameter) made twenty-four revolutions per minute. RestorationIn February of 1994, Eureka exited San Francisco Drydock after a $2.7 million restoration project. The steamship had been in the shipyard since October, where a crew of 45 skilled craftsmen caulked 2.5 miles of planking seams, and hammered in over 9000 eight-inch spikes. They applied stockholm tar, laid Irish Felt, and then plated the hull with 12,000 square feet of shining copper (cut down from modern dimensions to traditional-sized pieces to maintain the historical facade). |
