Exploring: Ark Rock Boiler Wreck #3

We did two short exploration dives around Ark Rock on 21 March. The first was to a small wreck roughly east of the rock itself, and the second one was to check out a pair of boilers lying on the sand s short distance apart. There’s nothing else around except for some rocky reef, which Tony and I explored for a while after we were done with the boiler.

The boiler looks quite imposing – for the technicalities on fire boxes and things visit the Wikivoyage page for Ark Rock, but it’s solitary and impressive. There are no other bits of wreckage lying around. Most of the boiler is very overgrown, and we found a huge roman hiding in one of the holes in the boiler.

The rocky reef close to the boiler is covered with sea cucumbers, Stephens codium, brittle stars and feather stars.

Tony and I were fascinated with the sea pens sticking out of the sand, and I spent quite a while watching a warty pleurobranch trying to walk over a brittle star (who fought back).

We took a slow swim around the reef and back to the boiler and the shot line, which was on the sand nearby. The water was very green, but the visibility was fairly respectable!
