Diving notes

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 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.
