Convex VX
Tige's fiberglass hull-extension device that attaches to the swim platform and extends the running surface, channeling propeller water down into the wave to increase its size, volume, and density.
Convex VX 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 Convex VX 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 Convex VX 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 Convex VX is a fiberglass Convex V hull-extension device developed to enhance the running surface of a Tige at wakesurf speeds. It attaches to the swim platform and extends the shape of the hull rearward, working hand-in-hand with TAPS and the Convex V hull to deliver complete wake control and dial in the surf wave on either side. The center tunnel of the Convex VX channels water from the propulsion system downward, under, and into the wave, harnessing the energy generated by the prop to increase the size, volume, and density of the surf wave.
