Diving the Derwent

On Thursday 12 April, Dave, Sandy and Craig dived the former HMAS Derwent west of Rottnest Island, Western Australia, which lies in 200m of water. The descent took 6 minutes and just under 9 minutes was spent on the wreck. Then 7 hours and 45 minutes decompression for a total runtime of 8 hours almost to the minute.
Dave and Sandy were diving their rEvo rebreathers with a modified Inspiration as a backup rebreather. Craig used his twin Megalodon (the MultiMeg).
Many thanks to Luke Nelson of Image Dive for putting us on the wreck, and Mark (Wiz) Brown, Darron Ellingford, Mick Green and Kim Halliday for their fantastic support on the day.
For those of you diving from substandard dive boats in other parts of the world: this my friends, is how we look after the divers in the West:

Video of the dive coming soon. In the meantime, here is a short clip of a visitor that joined us for about an hour of the decompression. We reckon he's a Bronze Whaler, but any more educated opinions from those that know more than us would be welcomed. Anyway, he seemed friendly.

There is information on the HMAS Derwent on the Royal Australian Navy website at www.navy.gov.au/HMAS_Derwent and on Wikipedia at en.wikipedia.org/wiki/HMAS_Derwent_%28DE_49%29
