Based off the original design that sparked the whirlwind of surf-enhancing devices, the Eight.3 Concave Blade 138 Wakesurf Shaper utilizes a super easy and non-invasive suction cup attachment that's perfect for those who may not have a flush surface area at the optimal mounting spot. Going pound for pound with the OG Blade model, The Blade 138 Concave Suction Cup Wakesurf Shaper displaces the same amount of water and performs optimally when it's 80% submerged and placed as close to the stern as your hull will allow. Gone are the days of saying, "our boat's wake isn't big enough to surf..." The Eight.3 The Blade 138 Concave Suction Cup Wakesurf Shaper has arrived!
