Three most important things to keep in mind when fishing the seaway.
Just by keeping your eyes open to whats going on around you can lead you to unique fishing opportunites that others may miss. That is not only looking for birds that are over fish but also any surface action even if it is just a single boil or a spray of baitfish. Keeping a constant eye on your sounder is also important.
Move around based on what the tide is doing, if the tide is just about to run in you should be at the ends of the walls waiting for the first push of the tide around the front of the walls and the clean water to push in, at Dawn or Dusk you should be concentrating around the major fish holding areas like the North Wall/Pipeline/Canyon. Never get so carried away with collecting bait that you miss the major bite periods - first hour of the run-in, last hour of the run-in, first hour of the runout.
When using a specific lure or bait, pay attention to where it is at all times. If you are using a microjig keep it within 2 metres of the bottom, same with plastics and live baits. You should be constantly dropping them to the bottom and lifting them up a metre just to make sure. If you are fishing the edges, make sure your lure is landing within 1 metre of the rock edge or closer... as close as you dare. If you aren't getting snagged occasionally, you aren't getting close enough. If you are casting into feeding fish aim for the thickest part of the bustup. When trolling make sure the lure is running no more than a couple of metres over the top of the fish or the bottom.
Paying attention to these three things will catch you more fish than spending any amount of money on expensive fishing gear or fancy boats.
