Diving notes

The Comet has a sad story to tell. Built at Portsmouth, Ontario in 1848, his first accident occured when it hit a shoal in the St.Lawrence River and sank. The wreck was refloated, repaired and returned to service. The second accident occured in November 1849 near Toronto when a steam pipe exploded and killed 2 crew members and severily wounded a third one. The third accident killed 8 crew members when the boiler exploded at Oswego in 1851. The ship sank again and was refloated and renamed Mayflower. It was renamed again with its original Comet in 1854. Finally, on May 15 1861, it came into a collision with the American schooner Exchange. The Comet was hit at the bow and sanked killing 2 crew members.

The Comet was used as a passengers’ carrier.

The wreck was found by 6 divers in October 1967 after 5 years of search. At the time of the discovery, many ship’s pieces have been taken out of water and given to the Marine Museum of the Great Lakes at Kingston.

The two wheels padder offers a charming experience to the dive. Their size are impressive, about 25 feet in diameter. They are parts of the most intact section of the wreck. The stern and the bow have collapsed. The middle of the wrech worths the dive to see. Under the low deck, two boilers can be seen. The chemney sits on the starboard middle side of the wreck. There is a large field of debris on the starbord with a lots of farm tools.

It is possible for divers well equipped and trained with experience to do a penetration dive under the deck at the back.

Due to the depth, it is recommended to well plan the dive bottom time before the dive. The Comet is below the thermocline. There is no current on the site. A dive lamp is highly recommended to see all the details of the wreck. The visibility is sometimes quite awasome on the site.

The wreck is covered with light silt. It is recommended to have a good boyancy to avoid lifting the silt and reduce the visibility around as well as the one of the other divers. It is a deep dive, you need to check your bottom dive time.

Like all the shipwrecks in Ontario, the shipwreck is Ontario’s Goverment property and therefore it is stricly forbidden to take any objects.
