Mast extensions

Buying a Windsurf mast extender

The windsurf mast extender is an important part between the mast and the baseplate. It is in fact a coupling piece and should definitely not be missing!

We make a distinction between an SDM mast extender and an RDM mast extender. Depending on the type of mast you are sailing, you should choose the type of extender.

Which length of mast extender do I need?

The windsurf mast extenders are available in different sizes and can be easily adjusted. To choose the right size you have to take the luff size of your sail minus the mast size. If the size does not match it is best to round up.

For example: if you have a luff of 479, you will use a 460 mast. Subtract 460 from 479 and you get 19 centimeters. This means that you need a mast extender that is not much bigger than 19 centimeters. In this case, a 30cm mast extender would be perfect, because now you also have some room for adjustment.
