The high-quality “all-rounder” with a carbon content of 55% and impressive overall performance.

The North Silver windsurfing mast series is also produced in AEROSPACE.PREPREG.TECHNOLOGY resulting in a reduced weight and even better flex.

A groundbreaking development in the NorthSails mast construction is the POLY.SHIELD coating. This is a highly abrasion-resistant material that is also used for ski and snowboard bases and is unique in its capabilities. Carbon fiber is very stiff, but not particularly resistant to abrasion. Especially in the area of the boom and camber, but also at the mast leading edge, the carbon fibers are now effectively protected by the POLY.SHIELD against abrasion. As the only brand we use un-dyed polyamide, in its natural white color, which improves the abrasion resistance compared to dyed polyamides by 20%. The POLY.SHIELD covers the entire surface of all PLATINUM and GOLD masts, as well as the base of the SILVER SERIES! This means no more wear, scratches or damage to the carbon fibers.

NorthSails uses T600 carbon for SILVER masts. The elongation measures the traction during bending until the fiber finally breaks. For a Windsurf mast this means: The higher the bending-elongation value of the carbon fiber raw material:

• The faster the reflex speed (which ultimately increases the performance of your sail, similar to increased horse power in a car)
  
• The higher the breakage strength

Carbon fibers are available with bending-elongation values between T300 and up to max T1000 with the T1000 carbon being 10-times as expensive as cheap T300 carbon. The lowest quality carbon fibers used on Windsurf masts have an elongation value of T300-400. This carbon has a bending-elongation that is just slightly higher than glass fiber. Therefore it’s used on cheap “low-percentage carbon masts” only. 80% of all brands nowadays use T400-500 for their top-level carbon masts.
