First, go here:  
http://www.cncphotoalbum.com/doityourself/rod_rig_tuning.htm

If entering via the website home page, go to the DIY link on the left side 
bar and then find the Rod Rigging - Generic Tune link.

The first few steps will instruct you on how to center the masthead and 
make sure the mast is in column.  Next it deals with rake.

For boats with double lower shrouds, the tension settings below should be 
a good starting point.  They are stated in terms of wire breaking strength 
so the are wire size independent.

Uppers - 21%
Forward lowers - 14%
Aft lowers - 5-6%

I have used the following technique on many different boats without using 
a Loos gage. First, I check that the mast is straight athwartship 
(sideways) and that I have the desired rake which is different for each 
boat.  I tighten the turnbuckles on the fore and aft stays first.  I check 
the tension by pulling on them at about chest height.  The stays should 
move no more than about one inch.  The same applies to the upper shrouds. 
On boats that have only one lower, I tighten them until I can pull about 1 
1/2 inches.  On boats that have two lowers, I tighten the forward lowers 
until I can pull about 1 1/2 inches.  On the aft lowers I use about 2 
inches.

The next step is to check the tension out under sail.  First I make sure 
that the mast is straight.  This will tell me if the lower shrouds are 
correct.  There may be some slop on the downwind side depending on the 
wind speed.

Adjusting rake is another procedure depending on the weather helm of the 
boat.

Chris,
I do not use a Loos gage on Beemer, 29mkll, to tune my rig. My process is 
as follows.
With all stays and shrouds lose, I tension the stays so I have 
approximately 9 inches rake along the boom using a weight on the main 
halyard. Forestay first, then backstay to remove slop. I them tension the 
upper shrouds to hand tight and using the main halyard on the toe rails to 
align the masthead. I then add two turns to the turnbuckles. Check 
masthead alignment again. 
Once all aligned, I tighten the lowers hand tight. Sight the mast to 
ensure straight. Add two turns to each lower. Sight the mast. 
Time for on the water final tune. In roughly 10-12 knots of wind on beem 
reach, look at leeward shrouds for play. Removed a third of the play 
tightening the leeward turnbuckles. Count and remember the number of 
turns. Tack boat. Tighten leeward turnbuckle same Number of turns as 
previous tack. 
And I tack back and forth checking and making any final adjustments. 
You'll want the slop out of the leeward shrouds. 
Sounds like a long process but it really isn't. 
Is using s Loos gage quicker? Yes but I'm a cheap son of a gun. And even 
with a Loos gage you'll still occasional on water adjustments.

Re: Stus-List Stay Shroud Tension

[Chris via CnC-List]

Thank you for the reply , but that is to technical for me . I have only had
one sailing lesson , so I do not know much about  sailing or rigging . The
people at the sail club I joined said the lines have a certain tension and
since my boat is a 1975 I do not have any info for how much tension. I
would like to set it by a gauge for now.

Re: Stus-List Vent recommendations 30MkII

[Chris via CnC-List]

I have a C 24 was wondering if you know how many pounds of tension are
needed on all the lines that hold the mast in place?
