Windsurf boards are selected by their volume (in liters) and length (in centimeters). High volume boards offer stability and flotation. They are also used in light wind conditions.

What do the numbers on a windsurf sail mean?

The industry standard terms describing windsurfing mast bend curves are: 0-6 = Hard top. 7-9 = Hard Top/Constant Curve. 10-12 = Constant Curve.

What is the biggest windsurf sail?

The longest windsurfing journey:

How long do windsurfing sails last?

How long is a windsurf mast?

Most windsurfing sails cite the ideal mast length for a given sail on the sail’s bag and/or near the bottom of the sail itself. Common mast sizes are 370, 400, 430 and 460 centimeters. If your sail doesn’t offer an ideal mast listing, look for a “Luff” measurement.

What is mast IMCS?


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. Hence longer masts are made stiffer than shorter masts.
