Does anyone know if the 423's were ever fitting with a shorter mast .
Spicerr:
The short answer is NO...but they did make a taller rig which was called the 'tall' or 'performance' rig.
The 'standard' 423 mast is:
"P" for the Classic mainsail is: 13.24m
"P" for the Furling mainsail is: 13.08m
and the "P" for the Tall rig is 13.94m
The 'E' measurement for all 3 was: 4.52m
The "I' measurement for the standard mast is: 14.83m
The "I" for the performance rig is: 15.08
And the "J" is the same for all: 5.035
Hope this helps and if you have any questions about the rig or sails, I'd be happy to answer.
