About Granite Wreck

The Granite Wreck is the remains of a huge, nameless wooden sailing ship. The ship is barely sanded in at all so one can see much of its structure. The site is so called because of the large stone blocks lying in rows on top of the ribs of the ship. The fallen walls of the hull of the ship are themselves alone much larger than many wooden wrecks of a similar type. A chain pile, broken-down donkey boiler and winch mark the bow, and a mast lies midship, diagonally across the wreck. An old scallop dredge marks the aft end of the keel. The edges of the wreck are full of deep holes formed by the ribs and the outer and inner planking. These holes are inhabited by lobsters but are not ideal for divers as they can be very deep and the lobsters can escape. The lobsters are easier to catch under the stones, another hiding place. This dive is fantastic on a clear day, regardless of whether or not you find lobsters. When swimming above the wreck its ribs and keel can look like the skeleton of a huge, ancient creature. Artifacts are also found occasionally and, when diving, you can hear the sounds of the propellers of passing freighters above. As the stone blocks on the wreck are too large to be ballast it is almost certain that they were cargo. When small samples of the stones were taken they were found to be calcareous in nature and were peppered with marine boring organisms. These features are indicative of marble and borers would be unable to make any progress in granite so perhaps the name of the wreck is misleading.
