North Graham Shoal BuoyThe buoy lying next to the rudder came from North Graham Shoal located in the Straits of Mackinac on the northeast side of the Mackinac Bridge. At 30' in length and 7' in circumference at its center, it is known as a "large nun" buoy. This type of buoy was constructed of the best quality charcoal iron and the plates were put together with hot rivets, making the joints watertight. The construction called for the creation of several individual watertight compartments, which prevented the buoy from sinking if it was damaged by a passing vessel and began to take on water. The use of this particular type of buoy discontinued in 1899 and although it has signs



of red paint on it still, due to a change in buoy coloring system recommended by a League of Nations subcommittee in 1936, the buoy now located on North Graham Shoal is green.
