ALMA is an excellent example of a once-common, vernacular work-a-day craft found on the major waterways of the United States from Colonial times through the 20th century. While built and operated on the San Francisco Bay, ALMA is in many ways indistinguishable from scows which were launched and sailed on the Chesapeake Bay, the Gulf Coast, the Great Lakes, inland rivers, and other coastal waters of the United States. No scow schooner save ALMA is known to survive afloat in the United States.
