The wooden scow-schooner Martha G. was built in 1907 at Washington Harbor, Wisconsin by Junius V. Garrett. Apparently, the vessel was originally named Delta Ann. The vessel was used to haul building materials, often bolts. Martha G. worked out of Washington Island going to places such as Green Bay , Sturgeon Bay and Escanaba.
