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.
