I'm looking into buying 2 drift socks for my 24 pontoon. I'll be using them on the santee cooper lakes as well as my home waters. What size drift sock do you think i would need? I plan on deploying 2 socks at a time on each end of the boat. Would 2 30 inch socks do the trick, would 2 36 socks be overkill? Any info would be helpful, thanks.
