I was shooting anywhere I could get my jig. Mostly between the boats and the dock and all the way to the inside of the dock under the lip, towards the bow of the boats. I would let the jig fall for a bit and then gradually reel it back. I would either get a thump immediately or on the reel back. I wasn't there that long but next time I go back I will be there 1st thing.
I've shot the Little Axe dock too but you have to get there early on a Wednesday or else it is crowded!
Here is a pic of the 1st one I got off the marina.
