Cheynes III is a 47.9 m whale chaser scuttled as an artificial reef in 1982, lying off the western side of Michaelmas Island in King George Sound. Her deepest point is 23 m and visibility averages 10-15 m. She is sheltered enough to dive in most weather, with south to south-west winds the exception.

The dive

This is a compact wreck: at 47.9 m long, one dive covers her end to end with time left to go back over anything worth a second look. The deepest point is 23 m, so the profile is simple - drop onto the hull, work the deep end while the gas is fresh, then spend the back half of the dive over the shallower structure and finish with an unhurried ascent.

Ten to fifteen metres of visibility is enough to read the shape of a whale chaser rather than a section at a time, and at 47.9 m she is small enough to take in on one dive. She has been on the bottom off the western side of Michaelmas Island since 1982, and the island shelters her well enough that she dives in most weather - south to south-west winds are the exception that takes her off the list.
