Diving notes

The picture on the left shows where the entry point à ~60’ will conduct you. The central picture shows the wheel house. The picture on the right shows where the entry point at ~20’ will lead you.

From the quay, the boat has to go South (S-SE) in American waters ~1.5km away, past Grenadier Island. There are 2 buoys (black or red) which mark the location of the shipwreck. The 1st one allows diver to reach the bow within depth of 20’. The 2nd allows the diver to reach the central mast at 60’ deep.

At this location the boat may be attach to the buoy. Take note the american laws applies, the dive flag is mandatory.

The Keystorm had a short service life. Built in England in 1910 for a Montreal company, the ship was sailing in dense fog conditions when he hit a shoal. The pumps were activated immediately to delay as much as possible the sinking of the ship. It took 5 hours to sank which gave plenty of time to the 20 crew members to evacuate the ship.

The enquiry revealed that the captain and the officiers have been negligent during the sail, which caused the loss of the ship.

Its coal cargo was recuperated 9 years later.

The Keystorm is still in good condition. It sits on its starboard side. The bow is at 25 feet deep while the stern is at about 100 feet deep.

Divers of any certification levels can visit the site. The cabin can be seen at about 60 feet deep. At a lower depth, the holds the engines’ room can be seen. The propeller can be seen at 115 feet deep.

With proper equipment, training and experience, it is possible to do penetration dive around the bow and the stren.

There is a cavity where the anchor was and were now some air is trapped. It is not recommended to breath that air.

Low water current and a good visibility are generally the conditions on the site. A dive lamp is highly recommended to see the spots where natural lighting can`t strike.

The shipwreck offers a great deals of possibilities to different certification level of divers. A dive between 20 to 115’ deep is possible. This is a site I appreciated. Some has indicated an important deep water current.
