Before buying a windsurfing mast, it is important to look at the specifications of your sail. With Gaastra, it is important to pay attention to the bending curve. Since 2017, Gaastra has switched from hardtop masts to constant curve masts. So if you still have a pre-2017 sail, make sure you buy a hardtop mast!

A Gaastra sail goes best with a Gaastra mast due to the constant curve mast that Gaastra uses. Especially the size, carbon and curve are very important to look at. The more carbon in the mast the lighter and more performance you can get out of the sail.
The SDM mast is one of the most widely used masts, if you are going to freestyle or wave windsurfing we recommend you look at the RDM masts from Gaastra.
