drift fishing is about expansive grass flats, and taking advantage of beating coast wind.
Kars, you're probably right about the bot.
You set a drift sock, run it to the stern using your trolley, sit back easy, and blind-fish downwind.
When you catch fish, you take up your drift sock, paddle back up, and try it again.

here is 18-kt NNW
A normal day is crossing the grass flat to the fish-concentrating structure upwind to fish there - always planned around the wind, and best planned with the tide.
Then drift fish the flat to work your way back home.
good places to drift fish on the prevailing wind include Brown&Root and Estes flats, also Outside Beach at Estes.
East Flats just above is killer on a W to NW wind.
In a power boat, you normally just let it windcock so everyone in the boat can fish easy. From South Padre on the prevailing wind, you can set up 10-mi drifts between the grassline and ICW. But normally, if you're not finding fish, you run and try another spot, and when you find fish, run back up and drift again.
This is the west side of Green Island, which has a bit of everything with the nearby flounder hole - east side is too skinny for the power boat, but a great place to mothership a kayak.
