Aquarius Sail Owners

I recently purchased a 33' mast and squaretop main and jib from a supercat 19xl for use on my supercat 20... The mast came with all the rigging dismantled so I'm trying to find out if this setup requires prebend or not and if so... how much prebend is required? Also....the jib was a self tacker with...

can anyone tell me if the supercat 20 mainsail is the same sq footage as the sc19xl tall rig sqaretop main made by posey sails and the self tacking jib?
thanks!
