Three-masted schooner Boaz was built in 1869 by Amos C. Stoakes, one of the leading shipbuilders in Sheboygan, Wisconsin. At the time of its enrollment, the Boaz measured 83 feet long with a gross capacity tonnage of 96.71. Boaz's 31-year career was spent shipping lumber and lumber products on Lake Michigan. In early November 1873 Boaz was caught in a squall that drove the vessel over Whaleback Shoal in Green Bay, forcing the crew to cut the masts down; the schooner was found drifting near Menominee, Michigan, and towed by the propeller G.J. Truesdell back to Milwaukee. It was not only repaired but cut in half and lengthened by 32 feet to its current length, raising its gross tonnage by about 31 tons. This repair/modification is possibly when the unique second centerboard trunk was added to maintain stability of the lengthened vessel. Afterwards the ship continued to ship lumber, with little record until a mysterious disappearance in September 1878, caused by a delay where 20 year-old cook George Gunderson fell overboard and drowned. In November 1881, Boaz was shipping flour, oats, hat, bricks, and other sundries when it went ashore south of the piers in Manistee, Michigan. Abandonment of the ship was considered after its outfit was stripped and cargo recovered, however the schooner continued to sail.
On November 7, 1900, Boaz was bound for Racine, from Pierpont, Michigan, with a cargo of elm lumber when it was caught in a storm and strained to the point of leaking. The crew had trouble keeping the ship free of water, and Captain Larson attempted to run to nearby North Bay, but struck Marshal's Point when attempting to enter. Both anchors were dropped to keep the ship off the beach. Boaz waterlogged and sank to its deck. The crew prepared the yawl in case the schooner rolled over, and the four men spent the night in the exposed yawl. They were assisted by steambarge Two Myrtles the next day. Boaz was ran onto the beach and had its deck load of lumber removed over the next few days after an attempt to release the ship was deemed a total loss.
The Boaz lies in a small bay at the southwest end of Marshall's Point, North Bay, in 8 feet of water. The bottom is covered in light sand and weed-choked. The hull is generally intact to the turn of the bilge and the wreck is visible from the surface. It is one of only six known schooners in Wisconsin waters with double centerboard construction which makes Boaz notable. Mapped in a 1988 survey, Wisconsin Historical Society (WHS) archaeologists returned to the site in 1991, for a brief inspection where they recorded further details of the vessel's midship framing pattern. WHS archaeologists returned again in 2022 to resurvey the wreck. The schooner is a popular spot for snorkeling and kayaking.
