The C10 Logboat, approximately 20ft long in deep water. This is a particularly mobile part of the lake where the silt bottom moves every winter, covering or exposing objects on the bottom.
Very little is currently known about this vessel, but I couldn't resist the photo opportunity.
The vessel is damaged at the stern, with the starboard quarter section displaced outwards. It would have had a transom board across the stern, probably wedged in and caulked with moss and wax.
