Exit rocker (also called tail rocker) is the upward bend in the back third of the board's bottom curve, measured from under the rear foot to the tail. The other half of the rocker decision alongside entry rocker.

What it does on a surfboard

The tail's curve determines how the board releases off the top of a wave and how much drive it generates down the line. Higher exit rocker lifts the tail off the water, which makes the board pivot quickly and release into snaps and turns — but at the cost of straight-line speed. Flatter (lower) exit rocker keeps the tail close to the surface, which loads the rear fins on rail for sustained speed and drive — but the board is less reactive when you want to redirect quickly.

This is the rocker that grovel boards and step-ups both run flatter, just for different reasons. Grovels need every bit of speed they can scrape out of weak surf; step-ups need to hold a line through bigger faces without spinning out. Modern HPSBs sit in the middle, contest shortboards run high.

What to look for

Lundquist boards run flatter exit rocker than peer HPSBs across the line — the same flat-rocker brand signature that shapes the entry. On the model page, look for LOW / MED / HIGH classification at the 5'10" reference: LOW = under 3%, MED = 3–3.5%, HIGH = over 3.5% (as a percentage of board length). Step-ups and grovelers run LOW; modern HPSBs run MED; contest pivot shortboards run HIGH.
