Standing rigging

[KingPalm]

Hello all.

I have a 1981 gulfstar sailmaster 39ft

I'm trying to find the lengths of standing rigging I need. My mast is laying on the deck currently and I would love to stand it soon. But I don't know the correct length of rigging that I'll need.

Where's the old rigging?

Previous owner never had any. I don't have anything to go by

This link may help as it gives all the specs including rig and sails..

Dang... In addition to Boatmans link, I would consider contacting rigging companies, both online and local, for information. And/or DIY with bulk wire and Sta-Lok's (or similar)

Couple of thoughts:
- Call Lazzara Yachts in Ft. Lauderdale. Vince Lazzara owned Gulf Star back then and maybe there is an outside chance (very outside) that someone there still has some technical rigging info, or knows where to find it.
- see if you can find a Gulfstar owner’s group. That rigging info might be found in an owner’s manual ( it’s in the owner’s manual of my Cal 39)
- find a sister ship and measure
- as mentioned above, stand the rig up with temporary rigging and build your own

Good luck

Just a warning…. Going by published sizes, even from the manufacturer, is fraught with peril. Consider it a starting point, not a specification to cut wires.

Boats change. Many are built to a low repeatability standard so even two hulls from the same mold have different length rigging. Minor, intentional changes in design have an effect.

I would never prep a rig for a boat based on a paper spec where I could not measure for myself. All I would guarantee is that the wires I delivered matched the spec, never that they would fit the boat.

It's not hard to get the length of the shrouds within the length of a rigging toggle.
The stays are the ones that you'll not be able to accurately measure for until the mast is up and using halyards to position fore-an-aft.

Another vote for stalok.

Published numbers are all very well but who knows what has been changed during the lifetime of the boat that would make them wrong.

We recently had a good rigger swage the upper fittings on to some over length stays and then we just cut each to the correct length and fitted stalok fittings at the bottom.

In this case you’d use the stays to hold the mast in position first, with all of the stays dangling down to deck level as the crane steps the mast.

Easy and relatively relaxing job.

Yes, and wires stretch too. A good rigger will know how to compensate for that. A neighbor in the boatyard just replaced the rod rigging on a Peterson 43 for wire rigging. The new wire backstay stretched over a foot more than he had accounted for.

A FOOT?
Jeepers, that sounds suspicious, are you sure they weren't raking the mast?

Yeah you're right but that was his claim! It's a tall mast but that is a lot of stretch, IF he was correct!
I'm going to check with him again, that is extreme!

Or he got his numbers wrong and was trying to hide it. Happened to a friend’s boat. Rigger said the boat had bent which is why some of the stays he made were now too short and needed extenders.

Yeah… sure. Except they were randomly distributed about the boat.

Step up the mast with halyards and cut the cables to the lengh needed !
