I hunt tidewater a lot and any incoming tide is good. I try and be out about 3 hours before the High tide and hunt the tide all the way in. I rig a 120' line with a weight and attach decoys with 2' droppers and longline clips. If the ducks are inside the last decoy they are in range. I sit on a bucket hunched over and I think the ducks mistake me for a stump or boulder. As the tide moves in I just pick up the bucket and drag the line of decoys in to the edge of the water again, no need to pick up decoys or adjust them. Best hunting seems to be when the water just transitions from the mud to the grass and all the time the grass is flooded. Be sure the wind isn't blowing into the area you want to hunt, the ducks don't seem to use it very much if the waves are breaking into it.
I only hunt the incoming tide and high slack as an outgoing tide can wash ducks away before you can get to them on foot.
Be careful out there , there is as much as an eleven foot tide change and a low spot that you walked through on the way out can be 5-6' deep at high tide and it can be a long wait for it to get shallow enough to get back to dryland. Also any small tidal drains that you stepped over at low tide disapear in the murky water and can make for a cold fall in the water.
I carry dry gloves and mittens in ziplock bag for the times I've lost my balance and have had to put a hand in the water to keep from doing a face plant in the water. Just wring the water out of the sleeve so it doesn't run down into the dry warm glove.
