SUP Rocker: What It Is And Why It Matters
How Curvature At The Ends of A Board Affects Performance
When selecting a paddle board, it is helpful to go beyond just the dimensions and outline shape of a board and consider an often disregarded aspect of SUP design known as rocker. The term “rocker” refers to the upward curvature at the ends of the board. The main types of rocker are called nose rocker and tail rocker, which is the upward lift at the front (nose) and back (tail) of the board.
It is important not to confuse rocker with ‘bowing’ which can occur to poor rigidity or sub par construction. Rocker is a deliberate characteristic given to board design for specific performance enhancements and is a desired element in a high performance SUP board. An optimized rocker profile works with the other physical factors of a boards primary design such as shape, length, width and thickness adding a unique feel to the board. The placement, angle and degree of rocker will vary depending on what the board shaper / designer is trying to achieve.
