Bow weight
Ballast loaded toward the front of the boat, which flattens the wake slightly but increases its length and smoothness.
Bow weight 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 Bow weight 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 Bow weight 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
Bow weight is ballast placed in the front (bow) of the boat. Adding bow weight flattens the wake a little while lengthening and smoothing it, producing a longer, more forgiving wave that's good for linking tricks and for beginners. A common starting balance is a 2:1 ratio, roughly 500 lbs in the bow for every 1,000 lbs in the rear lockers. Balancing bow and stern weight is how riders trade off wave height against wave length to suit their riding.
