Turn your wakes into swells with the hottest product to hit wakesurfing! This device is easily mounted to the lower/back point of the starboard or port side of your boat hull to create a premier surf wake on either side. This game changer means you no longer have to weight your boat unevenly. Instead of filling and draining port and starboard bags, now you can just keep it all in the center. Built-in handle makes it is easy to move the shaper to either side of your boat. Best when paired with a loaded ballast system. Comes complete with Wakesurf Shaper, 2 adjustable shims, and 4 adhesive fastener strips that attach to the boat, instructional USB, and an owner’s manual. New DesignThe Shaper design has been improved with more concave through the center of the Shaper and a greater, more defined leading edge. The result is a more effective job of diverting a column of water, thus creating less drag on the boat with improved fuel efficiency. This design is great for the surfer that wants the biggest inboard swell. Standard Size Dimensions Boat Surface Length: 15.5″ Water Surface Length: 21″ Height: 11″ Depth: 7.5″Shim OptionsThe shim is a simple attachment between the Wakesurf Shaper and the boat’s hull. Every hull shape is different. Some are mostly flat and don’t require a shim. Others have a step hull and require a 1″ shim. Still other boats have a more pronounced step and need a 2″ shim, while in some cases you might need both shims to make a 3″ gap between the hull and your Wakesurf Shaper. For installation, we recommend the Wakesurf Shaper is 80% submerged when the boat is properly weighted and as close to the stern as your hull will allow. Wakesurf Shaper PlacementThe adhesive fastener strips that attach to the boat are intentionally 6″ longer than the Wakesurf Shaper. This allows for further adjustment toward the bow or the stern of the boat, greatly altering the shape of the wake. When closer to the stern, the wake becomes steeper and deeper. When closer toward the bow, the wake gets a longer sweet spot.
