Personally we are generally less successful around slack tide. I think the fish like some movement. We fish in the islands a lot and I like to get in areas with a pretty fast drift. flip the ass end of the boat into the current and use the kicker to back down and keep my gear at a "reasonable" angle. Many times you will be flying over a spot and just freespooling line on the drop and WAM they grab it on the drop.

I would say that MOST of the fish we catch are when the water is moving.

Same goes for Possession, I like a little water movement to help cover ground. Otherwise your just drowning a sand dab in one spot. You're really looking for rogue fish that are cruising the flats. So drifting and covering water is effective. Same deal, we ass into it and control our drift with the kicker.

Dabs will stay alive in a cooler filled with water. They are hardy SOBs. Just change out 2/3 of the cooler water periodically to keep it clean.
