HAMMOND SCUBA FIELD GUIDE
Descending on an Upside‑Down Freighter: The Henry C. Daryaw Wreck off Brockville
A focused guide to diving the 220‑foot Henry C. Daryaw—an inverted steel freighter sitting at about 90 feet—compiled for public dive teams and operators.
Descending on an Upside‑Down Freighter: The Henry C. Daryaw Wreck off Brockville.
The Henry C. Daryaw is a 220‑foot steel freighter that struck a shoal in 1941, flipped as she went down and now rests upside down beside the channel wall with the deepest part at about 90 feet. The wreck lies roughly 6 miles west of Brockville, Ontario and about a quarter‑mile from shore, its exact position recorded by GPS for visiting dive teams.
