Boat: "Miles Ahead", John Lawler's 6.5m 175HP, Sorrento
Two VSAG boats (boat owners John Lawler and Mick Jeacle) headed out from Sorrento. John Lawler wasn't diving, but Bridely Leggart, Michael Kakafikas and myself were. On the other boat, Mick Jeacle, Greg Richards, Rob Kirk and John Merlo were all diving.
Port Phillip Bay was somewhat lumpy and unpleasant as we headed towards the heads. We swung by to pass some information on to Tom Wende on Midnight Raider on our way out. Crossing the Rip was a bit tricky, but the conditions were somewhat better outside.
Being ANZAC Day it was decided a dive on one of the Woorld War One submarines would be highly appropriate. We settled on the J1 Submarine.
Once on-site we geared up and went down. The plan was for a non-penetration dive. The shot was just off to the starboard side of the submarine towards the bow, but the path down to it took us right over the submarine.
We slowly made our way along the starboard side, from the bow to the stern checking out the marine life and occassionally peeking inside the sub. As we reach the stern I signalled to the others that I'd reached my turn around point and we headed back to the bow and the shot line.
We ascended to 18 metres for our deep stop for two minutes, and then continued on up to 5 metres for our safety stop.
On surfacing it was noticeable that conditions had become a lot better. Indeed, it was shaping up as a simply magnificent day out on the water.
We waited for the second group of divers on the other boat to complete there dive and headed over to chat to Tom Wende who was waiting for some divers on the Coogee.
Then the two VSAG boats headed through the Rip and into the shelter at Point Lonsdale for lunch.
