Most of the time one sock will do the job but have two just on case plus have the rigging to run them single of double. Brett you will only use them going with the wind and control the boat with your trolling motor like Keith said. Pull them in with going into the wind. I only let my socks out around 8' or so. If they don't work it is time to get off the lake anyways!!!! LOL Academy has them as a good price also. Heck I even have one for my kayak
