Duotone Foil Plate Shim 1° – Mast Angle Adjustment

Duotone Foil Plate Shim 1° – Fine-Tune Your Foil Setup

Sometimes a small adjustment can make a noticeable difference to how your foil rides. The Duotone Foil Plate Shim 1° allows you to adjust the angle between your foil mast and board, helping you fine-tune your setup for better trim, balance and riding comfort.

Designed to sit between the foil mast base plate and the board, this simple accessory provides a 1-degree angle adjustment, which can be used in either direction depending on how the shim is installed.

It's particularly useful for foil boards with rocker around the mast tracks, where the board's shape can influence the mast angle and overall riding position.

Why Use a Foil Plate Shim?

Every foil board has slightly different rocker and bottom contours. When you install your foil, these differences can affect the relationship between the board and mast.

A plate shim lets you make a small correction without changing your entire setup.

Key Benefits

• 1° mast angle adjustment: Fine-tune the angle between your foil mast and board.

• Positive or negative adjustment: Reverse the shim orientation to change the direction of the adjustment.

• Compensates for board rocker: Particularly useful when the foil mounting area isn't aligned with your preferred mast angle.

• Improves setup flexibility: Helps you dial in your foil position and riding balance.

• Simple installation: Fits between the mast plate and board.

• Genuine Duotone spare part: Designed for foil setup adjustments.

Small Adjustment, Noticeable Difference

If your foil feels slightly out of trim, the issue isn't always your wing size, stabiliser or footstrap position.

The angle at which the mast sits relative to the board can also influence how the setup behaves.

A plate shim allows you to experiment with that relationship, potentially improving board attitude during take-off and making your overall setup feel more natural.

For riders mixing different foil and board combinations, it can be a particularly useful tuning accessory.
