Surf side
The side of the wake, regular or goofy, that the boat is set up to surf, selectable on modern boats at the push of a button.
Surf side 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 side 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 side 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 surf side is whichever side of the wake the boat is configured to produce a clean surf wave on. Setup, through list, ballast bias, and the surf system, makes one side steep and rideable while the other side is washed out. Modern surf systems let the crew flip the surf side from regular (left) to goofy (right) instantly so riders of either stance, or riders trading off, can each get their preferred side. Matching the surf side to a rider's stance (regular vs goofy) lets them ride frontside, facing the wave, which is generally easier and more natural.
