After weeks of having crook weather, or one of us not being free to dive, or not able to drum up a dive buddy, we finally headed out to Mornington pier for a summer evenning dive.

I was a bit windy on arrival at Mornington, but the area was protected and the visibility looked reasonable.

We passed our gear down onto the inlet ledge and both entered the water via the inlet ledge. Travelled out on the surface to the end of the "Wild Thing" moring barge and then decended.

Plenty of Old Wives around to see. We slowly proceeded under the pier out towards the end of the pier. As we approached the end of the pier a seal joined us. After it left us we went either side of some pylons and the seal came back and joined me. Again it left, and then again it came back.

On reaching the end of the pier we went out along the rocks of the outer wall where we were joined by a rather larger stingray.

I signalled to Benita that my air was down to 100 bar. We headed up over the rock wall and back under the pier. We made our way slowly back to where the Old Wives were still gathered and hung about there until I was down to about 50 bar.

As we headed back in, we passed under the mooring barge and I found a large offcut of lead. Obviously someone had modified a keel, or dropped some balast. I salvaged it. Just as well my OMS BCD has a large carrying capacity!

We exited via the inlet ledge. Another fantastic dive.

The wind was now much stronger, though it had not made any difference to our dive.
