The hull of the Unknown 3 is intact but stripped, likely prior to its scuttling. It is positioned in shallow water and appears to have been deliberately sunk, a common preservation tactic in heritage conservation or yard cleanup. The surrounding environment includes other scuttled vessels and shoreline debris, with the hull possibly partially buried under silt, but visible frames and bulkheads are accessible.

Its dimensions suggest it may have been used as a canal scow for low-value bulk material in the early 20th century. The absence of registration plates indicates it was likely abandoned or decommissioned locally.
