Loos gauge numbers

Here are a few loos numbers I have put together so far. "0" on the mast jack is where the mast screw just engages with the mast post (2 or so turns from the very bottom).

Mast cap interm lower
0 just tight
3 11.5 sloppy sloppy
5 17.0 " "
6 18.5 " "
7 21.0 loose ""
8 22.5 tight tight
9 23.5 12.0 5
10 23.5 14.0 5
11 24.5 17.0 10

I found that in 10 - 12 knots of wind, 8 turns was perfect. Anything over 15 knots, and I would go with 11-12 turns. Bear in mind, that my Quantum main is cut very full. Depending on the wind this weekend, I may try to tighten the intermediates and lowers slightly.

Thanks Jonathon. It will be interesting to see how the numbers stack up overtime, especiqally in relation to different sails from other manufacturers.I'm having mine built by Doyle and will also be testing and calibrating using a loos gauge, and will share the info as I get it.
