How long is a windsurfer mast?

How do I choose a windsurf mast?

In case of recreational sails for intermediate windsurfers you should be looking at masts with carbon content from 60 to 80%. The 100% carbon masts are needed for the most performance oriented sails, usually used by experienced windsurfers.

Can you cut down a windsurfing mast?

Yep cutting a small bit of it is fine but if you cut too much, the diameter of the mast will get too small to accept the extension anyway…

What size windsurf mast do I need?

Determine your sail’s ideal mast length.

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.

What is the difference between SDM and RDM mast?

The simple answer: As their names suggest, the primary difference is that RDM masts are narrower in diameter than SDM masts. So much so, their narrowness requires a skinny (RDM) base extension and – in some cases – a shim to ensure a tight boom connection.

How much does it cost to downhaul windsurfing?

Once you are happy with the downhaul tension it is worth checking the space between the bottom of the sail and extension. You do not want this to be too great and we would recommend a maximum of 2 fingers and a minimum of one finger.

How long do windsurfing sails last?

It depends on harshness of use, but even when treated well, sails can only be expected to retain good shape for half to two-thirds of the structural life of a sail – that’s roughly 1,700 to 2,700 hours of use.
