Specialized race board generally come in lengths that conform to race classes. 12'6" is the most common race class, followed by 14'.
A 28-inch width board is narrow enough for many racers who don't want to push the limits of stability. A 26-inch width board will be a bit faster but the balance will be challenging on flat water and even harder in choppy conditions.
Race board shapes can be symmetrically rounded or can have a flat tail with the outline curving toward a narrower nose. Both shaping concepts can work equally well, but avoid getting too narrow at nose if you have any thoughts of paddling with a passenger on board.
