I've only done this dive three times, its a good slack water dive
and it can be done as a drift by the suitably qualified and
My most vivid memory of the first dive was seeing a large free
swimming conger enter a rocky depression. I tried to communicate
this to my buddy Keith, but hand signals being what they are, he
interpreted it as "there's a nice hole with a swim through at the
end, lets go in!" Which he promptly did. I must admit my estimation
of him (which was already pretty high) soared as I saw the cool way
he handled the 2m+ conger coming out of its lair and "mouthing" his
right leg as he negotiated the swim through! Even more surprising
was the lack of any reaction from him at all as he emerged. "What a

So you've been warned if you see a hole with swim through at the
end have good look before you stick you're head in!
The second occasion was far less eventful but just as enjoyable, we
descended through about 13m of water onto boulders and kelp. We then
swam east across the current and into deeper water where the reef
became less broken with depressions and gullies. The most memorable
feature was the incredible number of sea fans down there, arranged

my second. The drift was gentle (about 1/2 knot) but we were only
about 30 minutes into the dive and at about 25m when the bottom
dropped swiftly away from us. Being aware of the reverse profile we

disappointing vis. but still a most enjoyable dive.
Take care when doing this on an ebbing tide as the the bottom
rapidly drops away to 30m+.
