I would be in the same boat, I've been trying a few beaches around Kinsale, not great at all.. But i didn't have Crab so maybe that would be a factor..
I used catch so many Fish down off Cobh when I was in my teens, my buddies and I Honestly got sick of catching coalies, etc down there and that was the turning point for me, i then got into Fly Fishing for Salmon
that took me from catching so many to None for the first 2 1/2 years, but when I did, it was all worth it... I fished cobh last saturday morning and had 1 Big crab and 1 Massive conger!!
Everytime I fish around Ringaskiddy/ Paddy's Point, i blank.. I have only gotten dogs so far off monkstown, but haven't been fishing the wall as of yet...
I'm now trying beaches down the East side and they seem to be a bit better, so far... But it would be nice to head West again over christmas and the new year, goodluck in the adventures
