Power Wedge
Malibu and Axis's branded transom hydrofoil (current Power Wedge III) that lowers the stern to add wave size and adjust face length, offering six settings plus an on-plane Lift Mode.
Power Wedge is a term from limnology — the scientific study of inland waters. The detailed explanation below covers the definition, why the concept matters to lake water-quality interpretation, and how it intersects with the LakeGrade rubric. Reading Power Wedge alongside the LakeGrade rubric helps make the rubric's structure intuitive — each grading parameter maps directly onto an established limnological concept.
The per-lake pages on LakeQuality always show the specific Power Wedge value for that lake, so you can move from the general concept to the specific lake without leaving the site.
What It Means for Your Lake
The Power Wedge is Malibu and Axis's deployable reverse hydrofoil mounted at the transom. Power Wedge III shapes and lifts the wave for a fully custom experience, with six settings that let the rider define the wave's height, length, and shape. As it deploys, the back of the boat drops farther into the water; the deeper down positions lengthen and mellow the wave face without losing size. Power Wedge III also includes a Lift Mode that the system enters automatically to help the boat plane out faster when speed is set above surf speed. It works alongside Surf Gate so the wave can be tuned from either side, and it can be controlled remotely through the Surf Band.
