I have Broken bay, sydney heads and bate bay. I Only used the Bate bay one as I fished out of Port Hacking all the time. In your above picture of the Bate bay chart there is a reef we called boomerang reef due to its shape on the chart, you can only see part of it in your picture it is outside the two smaller reefs east of the port hacking, we caught good reds and other reef fish there by anchoring and berlying or just drifting. The charts show Jibbon reef, osborne shoals, the wanderes, the merries, the hole off wanda beach (sand) and other reef stucture. Again not shown on your above picture is a couple of sand gutters that run into the reef off Cape Bailey lighthouse, this area was our go to spot as long as the current wasnt racing. We would anchor and fish floating baits with minimal lead and we pulled numerous snapper from there, if we didnt get a 5lb fish we had a bad day. The biggest from this spot 13.5lbs and on that day we also got a 13lb one. Some days we would get several good fish. We used full pillies with a single 4/0 hook with the small sinker running to the hook. We didnt berley as this attracted the sweep which were then a pain.. Sorry for carrying on but the above picture brought back some memerios. I dont fish outside anymore as I sold my seafarer viking which I still regret about 8 years ago. I reckon it would still fish the same as when I fished years ago (we fished this spot for around 10 years). Also hooked a thresher shark there which I think are rare catch. Cheers all Glenn.
