This is a very accessible dive and is a great bit of reef, which descends down to sand at around 20 metres. It's not a commercial dive site, so you could see anything.
We've had a turtle circling around us wondering what we are.
Anchor the yacht in Chatham Bay. Anchor your dinghy next to the North-west headland in 6 metres depth where there's a gap between the headland and a small island. It's rock, reef and sand so try to hit a sandy patch.
Head south-west along a nice reef slowly descending to 20 metres to sand. Turn left and follow the reef south-east until you have used half of your air plus a reserve. Come up to 10-12 metres and head back north-west. Go past your dinghy anchor and continue to the point of the headland where there is a small vertical wall at 8 metres depth. Return south-West to your dinghy anchor.
Excellent bit of reef with some good fish life. We've seen big Porcupine Fish, Lobster and Tiger-tail Sea Cucumber.
