Adjusting Fore / Aft Movement

Fore/Aft movement refers to the vertical placement of the fins relative to the tail of the board. Moving the fins “aft” or backwards would bring them closer to the tail, whereas ”fore” or forward would move them further away from the tail.

The side fins should be moved together and should always be aligned horizontally with each other, whereas the centre fin can be moved without adjusting the side fins at the same time.

The 4WFS interdiscs have been specifically designed to provide 8 mm of movement for both side and centre fins.

When to move fins backwards (“aft”):

Moving the side fins backwards (i.e. towards the tail of the board) whilst moving the centre fin forwards will increase the boards responsiveness during turns.

When to move fins forwards (“fore”):

Moving the side fins forwards (i.e. towards the nose of the board) whilst moving the centre fin backwards will increase the boards speed particularly when driving down the line.
