Surf Tabs
MasterCraft's 2009 wake-shaping device, recognized as the first-ever production wakesurf shaping tab and the predecessor to the Gen 2 Surf System.
Surf Tabs 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 Surf Tabs 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 Surf Tabs 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
Surf Tabs were introduced by MasterCraft in 2009 as the first-ever wake-shaping device for wakesurfing, an innovation that earned the company the NMMA Innovation Award in 2010. The tab redirects water flow at the transom to convert a wakeboarding-style symmetrical wake into a one-sided surf wave. Surf Tabs established the template that later branded surf systems built upon, and the technology evolved into MasterCraft's Gen 2 Surf System, which paired the shaping device with integrated ballast and unifying software.
