Wreck Diver Course with Cape Dive,
Dunsborough.
Dive 4: Wreck penetration.
Anchored reel on main deck at 20 m, entered door at 27 m, through communications/accommodation
area,
rectifier room, cool room. Olaf was the reel diver on entry; I followed.
Then we swapped places,
Olaf exited first as buddy, I rolled up the reel.
There was a silt-out on the way out - a salutary experience.
Geoff managed to pop up by magic in several places - he knows the wreck well.
Need to practise handling lights and reel together!
Great fun.
A curious silver bream floated right in front of my mask. If you swim
gently backwards they become less
cautious.
Slow ascent to 5 m, good long pause, swim to boat at 3m, surface.
