Iron anchor stock on the lakebed, off the starboard bow.

Looking up from the bottom, wire rigging is visible suspended above the lake floor, perhaps hanging from the upright mast. Off the hull’s starboard side a shroud lays on the lakebed. Most likely from the starboard foremast, the shroud is draped from the starboard gunwale and extends away from the hull. A sail boom lays on the bottom next to the shroud, jaws intact.

Port-side hull from covering board down. Note small rubbing strake just above ROV heading near bottom of photo.

The hull exhibits longitudinal side planks and through bolts with clinch rings, perhaps for the bulwark stanchions. A heavy covering board was fastened atop the hull planks, and the bulwark was recessed from the outer hull by several inches. Remnants of white paint are still visible.
