far left as poss would be my choice although they can all fish along that stretch.

2nd to last jetty on left if your back is to morrisons is where the sand used to get loaded..so the bottom there is sandyish....would not bother casting out at all...just a flick out 5 yards towards the other jetty...maybe the same in the other direction. It's deep enough there and only the odd snag

at the very far left there is a hole in the fence which you can go through and get to some other decent spots...dock security will turn a blind eye..but I wouldn't go in the dark as I don't know my way .....
