Rewards came to the lads for braving the elements and waiting, well done mate.
Did the water look dirty?
The reason I ask, is cos I have had this happen to me twice just up the coast from where you went, just after storms and SouWesters like what we have just had... By Twice I mean same spot, same tide, two weeks apart, rotten weather in between wknds.
And we caught big 'uns directly below the boat in 20ft of water in the winter, where as, just after the storm this school sort of came up the berley trail direction and then slowly surrounded us for a mad hour before they moved off and in that time the biggest were straight below the boat, where as casting the floating bait out, as you do, with straylining, we were getting only the small snaps, trevally and kahawai.
This was really bizaare and maybe meant the big fish were perhaps more hungry and not afraid of approaching the noise and shadow of the boat, water viz was about 6 ft if that, it was overcast with patchy skies and passing showers with the SW squalls that come with it, and just as you describe the bites were finicky and small, but once we had sussed that and changed hook sizes it was all on...
So get out there after storms this time of the year ...
