It’s over 40″. Might be 48″? Not sure, exactly, and the boat is not here or I’d go measure it. I was thinking of adding a second sock to balance things out, but haven’t done it yet, and things actually work pretty well with just the one.

I’ve used just one drift sock on my 24′ boat to slow me down for Salmon Trolling. It runs right down the starboard side of my boat, about mid boat. Sure it pulls a little to that side, but really not all that noticeable. You might just give it a try with 1. One less item to get hung up.? Just a thought.
