N2,
I have a 1980 C30.
Here's the numbers I use. I use the "Loos" Tensioning gauges to do this.
These are reference point tensions. Depending on the age & stretch of you rigging, use these as a starting point.
Before you do this, check your chainplates and thru deck bolting and hopfully dry fiberglass first pal........
CR
Stays and Upper Shrouds
18-20% of wire breaking strength (1/4" 1x19 B.S. = 8200# x 18%-20% > 1476# - 1640#)
Forward Lower Shrouds
1/2 the percentage of upper shroud tension ( 3/16" 1x19 B.S. = 4700# x 9%-10% > 423# - 470#)
Aft Lower Shrouds
1/2 forward lower shroud tension (212# - 235#)
