The systems, devices, and methods described herein relate to a double layer racking board on a land-based drilling rig. The double layer racking board may include a drill pipe racking board and a casing racking board. The drill pipe racking board may be positioned at a different height than the casing racking board, such than operator is able to comfortably access drill pipe stands and casing stands of different heights via the racking boards. The double layer racking board may allow for the performance of a first drilling operation involving drill pipe stands at the same time as the performance of a second drilling operation involving casing.
