My sister, father and I found a long and narrow shipwreck. The wreck is 22 feet wide and the length that is exposed is 160 feet long (some of the wreck is under mud). The wreck has been in the water for at least 50 years (probably World War II). The deck is composed of wood. There appears to be a conning tower like structure. Is there some one that take a look at some sonar images and let me know if the wreck could be a U-Boat.
