Site Description The schooner is badly broken with pieces of the sides and many futtocks scattered about the site. An approximately 80 ft section of the keelson appears to be intact. The bottom appears to be rounded rather than the flat-bottomed style of hull of many Great Lakes schooners. There are still many parts of of the ship’s hardware extant on site including a wood stock anchor, the windlass drum, hawsepipe, centerboard, centerboard winch, and dual piston pump.
