Righting line should be at least 3/8 and tie a few square knots in it. Makes it easier to hold onto.
You could tie a loop near the bottom of the righting line for your harness hook to help leverage, as well as a loop near the top to help you step back on to the boat once it gets righted.
THIS is a GREAT idea! So simple, been doing this for quite a while, and never even thought of a foot loop in that line for getting back up.
Brilliant!
Except- it's usually in the middle/front, and the self taker kinda gets in the way.
