Hello Luiz-
The C31 1D is basically the same boat but has some mods [longer dagger,rudder, low tech interior, some carbon, smoothed amas, some have a canting carbon mast=179lbs, etc.] Translates into quite a new handicap... That boat really goes well. I don't know how it stacks up against the F32R,F33R or F35C. I think the Harvest Moon had both the F33R and F35c [underpowered sails] as well as a C31 1D. Go on the Corsair site and check it out. Farrier and Corsair split in 2000 I believe. The C36 is not a Farrier design.
