I converted a C&C24 from a masthead rig to a fractional rig last year,i had aquired the boat without a rig and there was a used J24 rig available in town with a small dent at deck
level which i was able to buy reasonable which is the only way it was worthwhile from a cost standpoint. I had to move the mast
foreward 20" to achieve the correct lead of the center of effort over the center of lateral plane.I cut the mast off just above the dent as it is now cabin
top stepped. From a sailing point i could not be happier,this is a sweet sailing boat that is perfectly balanced under every sail combination so far and i am very pleased with how it sails
under main alone.I should point out that i have never sailed a C&C24 with the stock rig so i cant compare but im sure it is better under main only as its much bigger but with the spinnaker
which i have not set up yet it is a lot smaller.The boat now looks right too.
