lol, lots and lots of wrecks on KY lake. the only one i know thats close to 150ft long is the USS Undine but she was covered with silt the last i heard when they found her at trace creek. if thats the bow and forecastle outline, then it kind of looks like the old tinclad gunboats. we used to pull nheads off the old wooden barges just south of the bridge in about 45ft of water. we just assumed they were wooden barges by feel.
local legend among the old divers is that there was a gold cannon sunk but i think it was probably brass. any cannons were probably salvaged by the Union after the war and the rest was probably picked over when they dropped the river in the 40's.
you might contact the tn war commission or the historical commission and ask them if they have any record of anything that sunk in the area you found it. at one time they were logging anything that was found and left standing of the towns after the flooding.
