[Alberg30] tunning, shroud tension

[Brian and Elaine Timmins]

These are the conclusions I drew from the list when it was published in May

Average tensions of the whole list:
Forestay/Backstay............733
       Backstay only...................726
       Forestay only....................735.6
Uppers.............................685
Fwd Lowers.....................495
Aft Lowers........................0   (loose)

Race Boats Only Averages:
Forestay only....................811
No backstay only
Uppers..............................862
Fwd Lowers......................679

Based on these numbers and info taken from Brion Toss's video on rig tuning
(and his web site), This is how I set up my mast.
Starting with the mast vertical, tighten the forestay to snug/tight  but not
to pull the mast forward of vertical.
Tighten the backstay to 625
Tighten uppers to 750
Tighten Fwd lowers to 620
Tighten Aft lowers to slack/100

After sailing a bit, I reset the backstay to 700
These numbers worked very well for me and the boat was nicely balanced.

Don't ask me to explain my logic anymore (this was done in June). I just
happened to come across my note sheet from doing the job.
All tensions were done with a Loos Model B, part # 90 gauge

Regards,
Brian
