Garth, are you sure about your shroud diameters? My interpretation of
the class rules is the uppers should be 5/16th (see page 23 in the class
rules on the class web site <http://santana22.com/static/clsrules.pdf>,
item 35):
Wire rigging shall be of the same dimensions and materials as supplied
by factory
except as to lower shrouds. Turnbuckles must be not less than factory
specifications as to dimensions and materials. No rod rigging is
permitted. It is
suggested that boats sailing in heavy air replace the factory supplied
5/32" lower
shrouds with 3/16" wire.
To be clear, I am not accusing you of being out of compliance (let alone
deliberately), just wondering if your uppers and lowers are indeed both
3/16ths.
Anybody else have fat uppers (or an opinion on the measurement rule)?
