tight vs. loose rig differences

Submitted by todd on Sun, 03/14/2004 - 22:53
What is the differenece between the tight rig and loose rig? I know the jib flys different, but is there any hardware or other suff involved. Additionally, how is the rig tension adjusted? is it like other boats, I am confused because the scot does not have a backstay and rig tuning seems more involved. Is a loos gage helpful? Thank for all replys. Todd

Hello Todd A backstay is not needed since the forestay and the shrouds form a triangle. The shrouds are mounted on the deck to the aft of the base of the mast. Thus the shrouds prevent the mast from going forward. The Flying Scot was designed for the loose. With this rig the toggle under the bow plate shows the correct tension between the halyard and the forestay, so that both have about the same tension and thus split the force between them equally. With the tight rig the toggle in effect lost its purpose since there will always be a greater tension on the forestay than on the halyard. Also with the tight rig the mast will be slightly more forward than with the loose rigging. The jibs for the tight rigging and the loose rigging are cut a little different. I'm not sure how much the difference is and how much of a difference it makes to use the other rigging than what the jib is designed for. If anyone knows, chime in. I'm curious about that. There have been quite a few discussions as far as what kind of rigging is better. Check out the old forum at [url]http://www.fssa.com/fsforum/[/url]. Some Tuning Guides:

Also don't forget that you won't be able to do the tight rigging with the aluminum winch since these may fail before the required tension is achieved. There is a lot more than what I know about tight vs. loose rigging. I just threw something out to start the discussion. It's not that bad if you don't get the tuning perfect. Just look at me, I've been doing it. This season I will probably go to a semi tight rig instead of the tight rig that I have used in the previous seasons. Mainly just to take some of the strain of the halyards. Hope I haven't said too many incorrect things.
