360

A full 360-degree rotation of board and rider, most commonly performed flat on the water's surface in skim style.

360 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 360 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 360 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

A 360 is a complete spin through 360 degrees. On the wake it is most often a surface 360, where the rider pivots the flat board around on the water without leaving the surface, a maneuver that skim-style boards perform easily thanks to their flat bottoms and minimal fins. An air 360 is the harder airborne version, rotating a full turn while off the lip. Spins like the 360 are the hallmark of skim-style freestyle and are markedly harder on finned surf boards, which resist pivoting.
