Site Description Although the two masted schooner is splayed out midship to stern the bow is fairly intact. The transom lies behind the ship disarticulated from the rest of the hull. The bow sprit and stays are intact. Two wood stock anchors sit on the bottom below where they were stowed. Visible rigging and machinery are the anchor windlass, anchor chains, catheads, the centerboard trunk (heeled over), the centerboard winch, tow masts toppled over, and booms although it is difficult to identify which are booms and which are mast pieces because the ends are under other wreckage. The rudder and tiller is also extant on site along with a number of deadeyes.
