The TrimShim stack-able hydrofoil shim system comprises of a set of specially made abs shims that lock-in to one another creating a stack-able shim. Each shim in the kit is at a 1 degree slant and there are 3 shims in this kit for up to 3 degrees of adjustment. The kit also includes 4 sets of wizardhat hardware with its patent pending articulating pivot allowing for full contact with the board track even at up to 5 degree tilt. It is only recommended to use the Wizardhat hardware with the TrimShim system.
Why you would want to shim your base plate?
The angle between your board and your fuselage is fixed due to the mounting or installation of the track in the board. There are different angles necessary for different foiling sports specifically for prone/SUP surf foiling, static foil pumping, and kite foiling. If you’re trying to use a kitefoil board for prone surfing it maybe helpful to change this angle to more easily catch the wave. Also, changing the angle between the board and fuselage will help immensely while static pumping off a dock or out at sea. You guys asked for it and FoilMount built it!
