Rigging Tension for Catalina 30

May 23, 2011

in Catalina 30,Tuning

Here is the generic advice for masthead rigs that my rigger gave at a recent seminar on rigging and tuning.

(Tensions in lbs. for the C-30 rigging is given in parentheses.)

Stays and Upper Shrouds

18-20% of wire breaking strength (1/4″ 1×19 B.S. = 8200# x 18%-20% > 1476# – 1640#)

Forward Lower Shrouds

1/2 the percentage of upper shroud tension ( 3/16″ 1×19 B.S. = 4700# x 9%-10% > 423# – 470#)

Aft Lower Shrouds

1/2 forward lower shroud tension (212# – 235#)
