A George Town-area reef dive worked from a fixed mooring, with colourful reef running along the edges of a mini-wall. The base of the mooring line sits at 35 ft (11 m) and the site's deeper ground reaches 70 ft (21 m), where massive sponges grow along the drop. The shallow top carries the rest of the dive once the deep end is done.

The dive

The mooring line is the spine of this dive. You follow it down to its base at 35 ft (11 m), onto reef at the top of the mini-wall, and that single point is where the dive begins and ends. Take a moment there to fix its position in your head before heading off along the edge, because it is the only fixed reference on the site and the reef around the lip looks much the same in every direction.

From the top of the mini-wall the ground falls away to 70 ft (21 m). That deeper edge is where the massive sponges are, so the usual plan is to drop over early, run along the face while gas and no-stop time allow it, then step back up onto the reef top. The colourful reef around the lip of the wall is what carries the rest of the dive, and the ascent and safety stop are done on the line you came down.
