Mast Treck
There are two types of mast track. A fixed mast track is the slot in the deck to which the deck plate is fastened (usually by a couple of finbolts). The position of the deck plate can be only adjusted while on the beach, and this system is generally found on short boards. Most long and mid-length boards have a sliding mast track, with a cup or 'car' into which the mast foot is fixed. The cup can then be moved backwards and forwards along the track by depressing a foot-pedal, allowing the rig to be repositioned for different conditions or points of sailing whilst on the water. However, sliding mast track represents an unnecessary complication for beginners, who would be best advised to leave the foot in the central position of the track while learning.
