| Boat Captain: John Lawler, VSAG Boat: "Miles Ahead", John Lawler's 6.5m 175HP, Sorrento Cheryl came along as a deckie to accompany John Lawler, Dave Kelly and myself on a dive to the HMAS Canberra. I had my twin setup along together with a single stage cylinder so that I could see what it would be like moving through the wreck with a stage cylinder for the first time. We headed out from Sorrento and tied up to the public mooring. John and David went in for their dive. On their return, I geared up and went in solo. The visibility was pretty bad but I made my way to the bridge and started to move around the area behind and bleow the bridge. So got the hang of tucking the stage under as I moved through narrow doorways etc. Made my way up to the forward mast and shot my DSMB. Took a compass reading and headed in what I hoped would be the right direction. I was having images of the others laughing as they watched my DSMB heading off course. However, the mooring buoy eventually came into view 2 metres ahead and I then changed track to where I thought the boat would be. We headed back inside the bay and had lunch. Then Dave and John did a drift dive on Boarfish Reef. We'd given Cheryl lessons on driving the boat, so left her to do so while the guys were in the water. She did an excellent job. So JL left her driving the boat as we headed back into Sorrento. Once we'd retrieved the boat and transferred our gear we all headed back to The Scuba Doctor in Rye. |
