Drifting sideways to the wind is may favorite way to crappie fish. Seems like the wind blows 75% of the time here in Florida. I have a 15' aluminum boat and the wind affects it pretty good. I use two socks, 54" in the front and 48" in the back. They slow it down enough in wind up to about 20MPH and control the boat from rocking as much. Ignore the charts that suggest the size for your boat. Buy BIG and be done with it. They last forever. I think mine were around 50 bucks a piece.
