  FINS & FIN SYSTEMS
 
 
  Futures, FCS II, and FCS Fusion fin systems and Bahne boxes are standard options for all fin configurations - single fins, 2 + 1s, twin fins, thrusters, quads, and convertibles. Glass on fins are also an available option. Glass on fins are particularly well suited for twin fins considering their large surface area and corresponding load on fins and removable fin systems.
