Not really.
Your boat’s rig dimensions are determined by the mast height. They can be generally derived from the
I, J, P lengths for the boat.

A rigger will use these numbers to get an approximate number to rough cut your shrouds. Then they will measure twice your actual rig length before the Final Cut. It is a cut to match length why a rigger prefers to do this work with the mast in the yard laying on a stand of sawhorses.
Thanks for the info... unfortunately, as far as I can tell, (and if this sounds grumpy, forgive me, please. I'm not even halfway through my 1st cup of coffee) that only gets me the lengths of the forestay and backstay (if it's not split, which mine is) ... but not the shrouds.
Part of the issue is that I'm 70 years old, and weigh a couple hundred pounds, and I'm alone. *I* am not going up there to measure. LOL I also think that if the manufacturer can publish the lengths of halyards, sheets, and other running rigging, why not the standing rigging? But I guess that was too much to ask for.
Looks like I'll have to run an ad for someone to climb the mast for cheap so I can measure it. I've done it before, just don't like spending the money... or getting all the responses that think I mean something other than an aluminum extrusion when I refer to a mast as well as some other action when I say I want them to climb it.
Guess I have a LOT of measuring to do.
