2021 CAB SPADE PROSPADE PRO CROSSOVER SURF Sizes: 53 x 18. 5 x 2 x 21L 57 x 19 x 2. 2 x 24. 9L This season we've tweaked the Spade in a few important ways. We've narrowed the width a bit to give the Spade's rail more contact with the water. Loading up the rail on a bottom turn or right before an air trick is now much easier. The Spade also now has a bottom channel right through the tail for lift and speed. We have added a 5th fin box to allow for a quad or a thruster
