| Dive Captain: John Lawler, VSAG Boat: "Raydon", Lloyd Borrett's Haines Hunter V17L, 130HP, Sorrento We headed out from Sorrento with two boats, mine and Bredan Hocking's. Brendan Hocking's Boat "Patriot":, a 6.8 metre Haines Hunter powered by a 225 HP, 4-stroke Mercury outboard. Brendan Hocking,Trevor Williams, David Flew, Christine Reynolds, and John Lawler. "Raydon": Lloyd Borrett, Cheryl Lees, Priya Cardinaletti, John Mills.and John Mills JL joinied or boat for the ride out to the HMAS Canberra. After some difficulty testing for radio contact just out from the ramp both VHF and 27 MGh were not responding all that well, but finally on one working channel made contact was made. The trip out through the heads was a very calm, almost flat journey to the HMAS Canberra dive site and Bass Straight was amazingly calm with slow, low rolling swells and on arrival at the site we had the place all to ourselves, not a charter boat in sight. On arrival at the dive site JL transferred to the other boat which then tied up to the public mooring. We tied off of that boat. The first teams kitted up and the dive line was tethered to the HMAS Canberra rail just down from the bridge. Cheryl and I geared up and went in. We desceded down onto the Canberra and made our way inside. The viability was down to around 6 metres, and the swell was noticeable but not uncomfortable or unsafe.We worked our way through various sections of the vessel before ending up at the bridge. We then made our way outside, found the line back to the boats and followed it. With Cheryl and myself back aboard, Priya and John Mills geared up and went in. They made there way on the surface until above the HMAS Canberra, and then descended. At the mast the viz was well down and the pair became separated. Priya decided to ascend but in the process the dump valve on the dry suit malfunctioned, causing an unusually rapid assent to the surface. Experience came into play here and she managed to surface without internal injury. Priya was back on the surface, calling for help and in obvious distress. Being closer, Trevor Williams rolled in and made his way over to help Priya. We untied from the other boat and made our way over to them. Priya was still struggling on the surface with her dry suit over inflated. Tevor managed to let some air out of the dry suit using the dump valves. About then, John arrived back on the surface and he and Trevor helped Priya back into the boat. Priya, usually in control and used to helping others in tricky situations, I think was more upset and distressed because suddenly she found herself in a situation where she was helpless. The dry suit had inflated so much that she was unable to reach the dump valves. Plus the force of everything was pressing on her neck. Eventually she started to settle back down and insisted she was fine. However, John and myself decided that the best place for her was back on land so we headed back to Sorrento straight away. We tried our best to prevent Priya from helping to unload the boat, insisting she just rest as much as possible. Priya and John then headed off home. We made our way back to The Scuba Doctor for air fills, then washed down the boat and put it in The Doc's shed. |
