Good flat sea, slight swell and current, moderate viz.
We followed the tether line to the dome at the top of the wreck, over the platform to a large cylindrical shaft, descended inside the shaft and explored the space under the wreck, filled with junk and large girders at 40 metres.
A huge Jewfish was lurking in the compartments at the bottom. It must have been about 1.5 m long. Also saw 2 lionfish and a very large cloud of bullseye. Footballers, Sergeant Baker, kingfish, samsonfish, banded sweep, Old Wife, Talma, scalyfin and foxfish.
After 13 m we ascended fairly promptly (but went into deco 1 min) to the platform and checked out the space under the dome before following the tether line up again.
It was very crowded at the 6 m stop on the line and most of us were too lazy to float midwater.
Fantastical sea jellies drifted past us - translucent spheres, mushrooms, "pillows", "cartoon teeth" shapes with phosphorescent cilia, long stringy arcs with crossbars.
My Apollo Pico backup computer was completely dead.
