Hi John, It does help for the process. Since my boat is in the water Already, with the stick up, do you set the upper pair (v2 & d2?) at a specific tension? While Sailing I won't be able to adjust above the spreaders so a pre-set number would be great.
And at no time should I let the lowers get "floppy" once I've settled in, right? Thanks for the help!
