Tucked Under Edge Meaning in Surfing

A tucked under edge describes a rail that is rounded but has a sharp base. This design helps the board release water more efficiently at very high speeds. The rounded top provides a forgiving feel while the sharp bottom offers grip. This is the most common rail design for modern high performance surfing boards. It allows for a smooth entry into turns without catching the rail edge. The tucked under edge provides a balance between stability and fast directional changes. A surfer carves a turn while the tucked under edge grips the face. This shape helps the board maintain momentum through the middle of a maneuver. One athlete zooms across a fast section thanks to the sharp bottom edge. This detail is a secret to the speed of modern surfboard designs.
