Masts
One of the most important choices you make when rigging a sail is which mast you put in the mast sleeve. Or, more specifically the length, curve and stiffness of the mast, and how closely these parameters match the sail. The mast is quite literally the backbone of the rig and it governs the sail's performance.
MCS curve and stiffness data for the Sailworks mast range is available here (PDF file, 12Kb).
An explanation of the MCS bend test and the calculation of the IMCS stiffness coefficient is explained here (PDF file, 29Kb).
