Mast Compatibility
I have a Sailworks 500cc 5 metre mast. It has a stiffness of 27.5 and the IMCS is 32.5.

When looking at compatibility with sails what number do I go off, 27.5 or 32.5 ?

Would this mast work properly with a Severne Reflex 4, 9.2m if the recomended mast for this sail is a 490/29

Thanks
Nigel
