Windsurfing Dictionary

All masts were originally constructed from glassfibre (epoxy) or aluminium. Although epoxy and aluminium masts still exist, most models on the market now feature a certain percentage of carbon for light weight and improved flex characteristics. The more carbon content (which can be as much as 60, 80 or even 100 percent) the more high performance and expensive the mast. The standard length of mast is 465cm, although they come in sizes ranging from 420-500cm. A mast
can be extended for use with larger sails by the addition of an adjustable mast extension at the base. (See also 'IMCS'). For much more information on masts click here .
