RedactedNarrative: The vessel owner and his 12 year old grandson were fishing at the inlet of Jones'' Creek, near Boy Scout Road - Operator from the bow, his grandson, Occupant, aft. Operator stated that about 5:45 AM Occupant declared his feet were getting wet. Operator stated that when he turned to look he quickly realized the boat was taking-on water - sinking. Because the engine was partially under water he decided to utilize the trolling motor to cross the main channel; it was his intention to tie-off to the closest residential boathouse. Operator further stated that as they got within 40 yards of a boathouse the boat struck bottom and lodged itself to a stop. He subsequently notified the property owner and the property owner agreed to allow him to keep the boat there until he retrieved his boat trailer and a retrieval wrecker. Operator eventually called Precision Wrecker Service; they assisted by towing the vessel onto the trailer.The reason the boat took-on water is unknown. When asked Operator stated, "It was not the plug. That''s the last thing [he] check(s) before putting the boat in the water."
