What do the numbers on a windsurf sail mean?

The mid-point deflection figure is applied to a formula that takes account of the mast’s length to give an IMCS number (Indexed Mast Check System) The bigger the number the stiffer the mast; IMCS numbers typically range from about 11 (soft junior mast) to 36 (stiff race mast).

Windsurf sails

A good all-round sail size for most people is 5.5-6.3m (18-20ft), suitable for winds of up to Forces four or five. However, if the wind strength increases further, then ultimately it will create too much power and pull to be able to control.

What is IMCS windsurfing?


The IMCS value indicates how much your mast bends under load. A lower IMCS indicates a more flexible, or ‘softer’ mast. Most mast manufacturers adhere to the more or less normalised stiffness for each mast length. E.g., 400 masts are often made at 19 IMCS, 430s at 21, 460s at 25 and 490s at 29.

What is an RDM mast?

Reduced Diameter Masts (RDMs) were originally introduced for wave-sailing as a solution for durability in waves due to their extra wall thickness that is more resistant to breaking when exposed to extreme flex in surf conditions. RDMs have an internal diameter of 32-33 mm. at the base.
