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.

Click on model name/logo to view details of each mast range or purchase.

An explanation of the MCS bend test and the calculation of the IMCS stiffness coefficient is explained here (PDF file, 29Kb).
