Grab

An air in which the rider grabs a rail of the board with one hand while airborne.

Grab 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 Grab 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 Grab 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 grab is an aerial trick where, after launching off the lip, the rider reaches down and holds onto a rail (edge) of the board during the flight before landing. Grabs add style and control to airs and borrow naming conventions from skateboarding and wakeboarding, such as indy and stalefish, depending on which hand grabs which rail. Because a grab requires a stable, high enough air to free a hand from balance duty, it is a more advanced air-based maneuver.
