This site was found in the 1970s by a commercial fisherman. The numbers were sold for $25, hence the name. Originally an armed Revenue Cutter like the RC Mohawk, the Walker was found to be less than satisfactory - the early steam propulsion systems were troublesome and inefficient. Eventually, the vessel was transferred from the Revenue Service to the Coast Survey Service, where it proved to be a vast improvement over the sail-powered vessels of the era for this sort of work. Being self-propelled, the Walker could simply motor up to the survey site and easily stay on station, not subject to the vagaries of the wind. The wreck was positively identified in 2013.

schooner barge
A beached schooner barge. Compare the hull form with a square barge.

The schooner barge was the final development of the working sailing ship. The design originally evolved in the 1870s on the Great Lakes, where it was found that sailing ships could be more profitably towed from place to place than sailed. No longer subject to the vagaries of the wind, such trips could be made on a scheduled basis, and with reduced labor costs. The idea spread into general use, resulting in the conversion of many sailing ships into barges. Ironically, most of the vessels that were converted to schooner barges were not actually schooners, but square-rigged ships. Square-riggers, with their large and expensive crews of skilled sailors, became uneconomical to operate in the face of ever-improving steam power, while more efficient schooners managed to compete for a few years longer.
