♦ Alma is a wooden-hulled scow schooner built in 1891 to carry bulk cargo.
♦ 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. By 1880 there were 250 sailing scows on San Francisco Bay.
