The last of her kind, Alma is an 1891 National Historic Landmark scow schooner. The flat-bottomed hull was designed to navigate the shallow waters of the Sacramento/San Joaquin Delta and to rest on the bottom at low tide. With few bridges and connecting roads, scow schooners delivered goods all over the Bay and Delta much as trucks do today.

An Unusual Scow Schooner
Fred Siemer came to San Francisco from Germany in 1865 and started his own shipyard at Hunters Point (located in the southeastern section of San Francisco). He constructed two scow schooners. Siemer named the first after his daughter, Adelia. After Adelia married, Siemer built the second scow for his son-in-law, James Peterson. That boat, constructed in Peterson’s front yard in 1891, was named for Peterson’s daughter, Alma.
Alma’s construction was not unique, but it was unusual; her bottom planking was laid athwartships (side-to-side) instead of fore-and-aft. Called "log built" because the horizontally-laid planks were quite thick, scows like Alma traded a bit of speed and ease-of-repair for economy and strength.
Alma hauled a wide variety of cargoes during her career. She carried hay and lumber under sail, and after Peterson removed her masts in 1918, she freighted sacks of Alviso salt while being towed as a barge. Frank Resech, who purchased the vessel in 1926, installed a gasoline engine in her, and from then until 1957 her cargo was exclusively oyster shell – carried in a 22’ by 36’ wooden bin installed on deck.
A number of sailing scows ended up as oyster shell dredges. The shell was free for the taking and vast deposits lay in the San Francisco Bay. Both Resech and his wife lived and worked aboard Alma for a time; Mrs. Resech handled the steering while her husband operated the dredging machinery. During those days, Alma hauled 110-125 tons of shell per week to Petaluma, California, where it was ground and used for chicken feed.
In 1943, Resech sold the vessel to Peter John Gambetta, who continued to operate it as a dredger until 1957. When Gambetta retired Alma she was still seaworthy, but no longer profitable.The State of California purchased Alma as she lay on the Alviso mudflats in 1959, and restoration work began in 1964. It was transferred to the National Park Service in 1978, and designated a National Historic Landmark in 1988.Alma is now part of the San Francisco Maritime National Historical Park’s fleet of historic vessels at Hyde Street Pier.
Scow Schooners on San Francisco Bay
Between 1850 and the early years of the 20th century, the best highways around the San Francisco Bay Area were the waterways, and the delivery trucks and tractor-trailer rigs of those days were the flat-bottomed scow schooners. Over 400 of these craft were constructed around the Bay. And although similar vessels were to be found in New England and on the shores of the Great Lakes, the basic "scow" design was adapted to local conditions, resulting in a craft uniquely suited to San Francisco Bay.
Able to navigate the Sacramento/San Joaquin Delta region’s shallow creeks, sloughs and channels, the scows’ strong, sturdy hulls could rest safely and securely on the bottom – providing a flat, stable platform for loading and unloading. Their squared bows and sterns not only maximized cargo space, but also make scows cheap and easy to build. Typically constructed of inexpensive Douglas fir, their design was so simple that most scows were built "by eye" – without plans of any kind.
Nicknamed "hay scows," it was common to see dozens of these small craft crowding San Francisco’s Hay Wharf each day of the April-October season. With deckloads of 600-700 bales, the scows had to "reef up" their sails to raise the booms over six tiers of hay. The wheel, too, was raised high above the deck so that the helmsman, standing aft on the "pulpit," could see to steer.
But scows hauled much more than hay. Until the 1870s, they carried Mt. Diablo coal to San Francisco; later, scows distributed English and Australian coal upriver. After the 1906 earthquake, the small boats freighted tons of still-warm brick from East and South Bay kilns to rebuild the City. Oregon lumber was always a common upriver cargo, and the boats hauled potatoes, onions and grain from the inland valleys to the Bay. Scows also transported gravel, sand, salt and fertilizer.
Although scow schooners (like their masters) were sturdy and hardworking, they also found time to relax. Scow owners traditionally sailed their boats to Paradise Cove (in MarinCounty) for family picnics in the spring. And the wide-decked craft were so often rented-out for evenings of dancing (and drinking) on the Bay that schoonermen had a special name for such excursions – they called them "drownding parties."
Reasonably priced, small and maneuverable enough for two or three men to operate, scows lured many enterprising salt-water sailors from the sea. Compared to their sea-going contemporaries, "tule sailors" (as scow schoonermen were called) lived very well indeed. A berth on deepwater square-rigger brought $25 a month and salt-pork; "tule sailors" earned double that and ate steak and farm-fresh vegetables besides.
Progress, in the form of gasoline engines, doomed these hearty sailing vessels, however. The last sailing scow schooner was built in 1906, and by the 1920s most scows had been rigged down to one mast. Some continued to work as barges or oystershell dredges. But in 1957, improved highways and motorized trucks squeezed even Alma, the last survivor, out of profitability.
Don’ Yib ‘en Polar!
For the most part, sailing scows "worked the tides" once they left the bay. But if a master was in a hurry on a calm Delta day he might order one of the crewmen to cast loose the yawl boat, break out the oars and tow eighty tons of scow and cargo behind him.
If a tree was conveniently placed, a line could be run from the craft’s windlass to the trunk, and the scow slowly hand-cranked upstream. Or, if the river banks were firm and flat enough, a line would be make fast to the foremast. Then a farm lad, eager to earn pocket change, would loop a canvas sling around his shoulder and pull the boat forward that way.
Sometimes, however, the channel was too shallow and the banks too steep or tree-less. Then there was nothing to do but put a shoulder to the twenty-foot "navigating poles" when the master called out, "Down the jib, and pole her!"
"The first trip we made was up to Sacramento: in fact, we made several trips between Frisco and that town … At times there were many floating tree stumps in the river. They generally float under the surface of the water and often when coming about you would foul such a log and have much trouble to get clear again. There logs are called ‘snakes’ and many times when the centerboard hits one in deep water, the centerboard will suddenly fly up in the air... One day as we were tacking up the river and everything was quiet and serene, I sat on top of the centerboard box peacefully smoking my pipe, when all of a sudden my pipe and I went sailing through the air and landed with a thump on the deck—the centerboard had hit a snake. Take my word for it, I never sat on the centerboard box after that."
Excerpted from the journals of C.J. Klitgaard, scow schoonerman.

#26 A Local Lifeline
The history and significance of the 1891, San Francisco Bay scow schooner Alma.
You’re listening to “Maritime Voices” from San Francisco Maritime National Historical Park. I’m Ranger Mark Neuweld. In this episode, we’ll consider the history and significance of the scow schooner Alma. Compared with the majestic Balclutha, Alma is a homebody. Built specifically for a hard-working life on San Francisco Bay, she has sailed local inland channels since 1891. Like modern flat bed freight trucks, she was designed to carry cargo. Before construction of the famous bridges of San Francisco Bay, Alma and hundreds of other scow schooners used waterways as highways to connect isolated communities of the Bay Area. A century ago in the town of Petaluma, residents would welcome Alma with excitement, for she was a lifeline to another world. What news and goods did she bring from San Francisco? San Francisco Bay scow schooners date back to the gold rush. In the days when the city ran on horses instead of cars, hay was as important as oil is today. Alma supplied Bay Area communities not only with hay, but also with other essential food and shelter, including grain, bricks, and lumber. San Franciscans would greet Alma with good cheer, for she might be carrying fresh eggs for breakfast from Petaluma. Scow schooners also connected families and friends in more direct ways. The scows were sometimes used for festive parties with music, dancing, picnicking and swimming. Alma Peterson has pleasant memories of such special days at Paradise Cove, north of San Francisco. “We’d take the husbands and the wives and the kids and old friends. We’d get over there and drink beer.” An estimated 400 scow schooners were built on San Francisco Bay, and Alma is the last of her kind. She still connects the communities of the Bay Area by participating in local maritime events and celebrations. San Francisco Maritime National Historical Park preserves Alma as a living monument to the tradition of local maritime commerce.
You’re listening to “Maritime Voices” from San Francisco Maritime National Historical Park. I’m Alice Watts, first mate on the scow schooner Alma. In this episode, we’ll consider the 1891 scow schooner Alma, more alive than ever!
Do you ever long for the “good old days?” If ships have souls, as some people believe, then the Alma may long for them too. although old in age, with her modern crew the Alma proves that she is still young in spirit. Listen to her new crew as this spirit is revealed.
“It’s like sailing your front porch…” states Al Lutz, Captain of the Alma. And, with her rectangular design not many people would argue with him. However, it took Al some time to learn how to sail a porch. Eventually, Captain Lutz realized that Alma’s sailing qualities were ideal for sailing on San Francisco Bay as well as up rivers and he regularly puts these qualities to use.
One such use is the “Gunk-Holing” trip. This trip takes her up quiet inland waterways, just as she would have done during her working days. And, with only three or four people to actually sail her, the trip proves to be physically exhausting. The trip also has its enlightening moments.
Alma’s first mate, Alice Watts, described one such experience. “It was like taking Alma back in time…” she said. “One time we used the current to carry us along. No sails were up, and the engines were off. It was so serene…”
Al and Alice also have tales of sailing Alma in the Master Mariners’ race in San Francisco Bay. This is a prestigious race that was first staged in 1867. Historically, participants were sailing merchant vessels, including many scow schooners. Today, participants include traditional sailing craft, historic replicas, and the Alma.
Al describes this race as “…beautiful or hell depending upon the wind and current.” In 2001, however, there was little current at all, and Alma took first place in her class! Not since the year 1870 had a scow schooner ever finished first.
Some look upon Alma and describe her as an “old ship.” In spite of her age, with her modern crew Alma maintains her vitality and proves she is not dead history.
