Mast rake shim. This rake shim has been specially developed for wind foil masts with a plate. The mast rake spacer is intended to change and fix the rake of the mast. These shims are resistant to the high pressure that comes on the shims. In addition, this spacer distributes the pressure completely over the bottom of the board.

You position these shims under the plate of the mast and the bottom. Then you tighten the wind foil firmly in the board.

The mast rake shim are available in 6 varieties;

• Shim of 0.5⁰
• Shim of 1⁰
• Shim of 1.5⁰
• Shim of 2⁰
• Shim of 2.5⁰
• Shim of 3⁰

Dimensions of the mast rake shim is: L 20 cm x W 7 cm

Please note, you may need longer bolts!

You may need longer bolts to slide the shims between the board and the foil. We sell stainless steel Torx bolts in various sizes
