If you rent a kayak you will have a lot more options.
First, if you go near the crab man marina between aransas and port A and paddle north across the channel towards the closest duck blind you get into "South Bay" which has potholes to the northwest and a small cut in the northeast corner, all very easily accessible from kayak.
For Wilson's cut, if you go down the road to the SOUTH with a kayak as far as you can go then cross the cut to the north and there are several sets of flats connected by channels. The second flat is the best with potholes to the northwest of the southeast entry point. Check Google Earth. Reds in both of these areas.
If you do not rent a kayak, you can still get to those flats at Wilson's Cut by staying to the RIGHT as you drive in. Go as far as you can which is only a few hundred yards. You then wade and walk down the cut until you are able to enter that area. It will take a while, maybe 30 minutes, but it can be done.
PLEASE be careful for stingrays in that area!
Lastly, I also frequent an area near or similar to SanAntoneAg. Here is a bit more detail. Headed towards Port A from Aransas, turn right into the last road before you get to the ferry. This is the entry into Brown and Root, which I understand you cannot follow the road the way we all used to. If you will CAREFULLY circle the water you can see as you first pull in, you can park on the opposite side of the channel and walk around a perfectly rectangular area called the "football field" for obvious reasons. Once you see that area on Google Earth you will know you are in the right spot. You can continue to walk towards the water to the north-northwest and cross a small channel and get to a shoreline that runs east-west. As you wade there are opportunities for speck and reds, and as you head to the west you will see a rounded inlet with a peninsula extending to the north. That rounded area is deeper and will usually hold fish. There is also usually a white buoy in the middle which is a crab trap. Halfway out on that peninsula is a small sunken boat that holds fish and is worth some time which may be what SanAntoneAg is referring to by "sailboat". If you are particularly adventurous, wade through the shell around the peninsula (carefully with good shoes on) and head west again. There is a large flat, very shallow, but with a gut to the southwest which usually holds flounder and may be worth the effort if you get lucky and they are there. This whole wade extends about a mile or so if you go all the way to the flounder cut. The "Pipeline" I think SAA is referring to is further west I believe and flanks a channel very close to this area, I think around one more island.
If you see any porpoises, just move. They are not your friends when it comes to putting fish in the box.
Again, watch for stingrays and oyster beds and good luck! Post a report if you can.
