Update on this boat!
Well me and a friend bought this boat in early Feb. We also contacted Fossfoam, and check out all other options as well. We decided to try to locate the rudder below the boat. By using an underwater camera system, we found the rudder. It was directly below the cockpit, and inverted.
Did I mention that it was in 26ft. of water, and the surface temp was 48, the depth below 17ft. was 42. We decided to use a snare to retrive the rudder, and was succesful today!
