The Roy A. Jodery is for experienced technical divers only. The depth, location and current all combine to create hazardous to treacherous conditions. The Jodery is a boat dive located in American waters at the Coast Guard Station directly in front of Alexandria Bay.

The largest ship that could fit through the locks of the Saint Lawrence Seaway, the Roy A. Jodrey sank on November 21, 1974, shortly after dropping her entire crew off ashore at Alexandria Bay, where she ran aground, about 17 yards from the “safe haven” of the Coast Guard Station, in the heart of the 1000 Islands.

The 640.5 foot Roy A. Jodrey slid off the island into over 250 feet of water. The Jodrey sits precariously on the side of the shipping channel on a wall of granite. The bow is at 140’, the wheelhouse is at 155’, and the props are at 242’. The extreme depth and extreme current has claimed many lives, including one of the investigators first sent to evaluate the wreck. Despite the heavy recreational and commercial boating traffic, it remains a mecca for certified and experienced diving enthusiasts with an interest in the largest ships ever to ply the Great Lakes.
