How far must a diving board extend beyond the pool wall?

The requirement for how far a diving board must extend beyond the pool wall is primarily based on safety and proper diving practice. An extension of at least 6 feet is necessary to ensure that divers have adequate space to complete their dives safely and land in the water without risk of hitting the pool wall.

This distance allows divers to gain the necessary momentum and minimize the potential for accidents or injury. The 6 feet extension ensures that a diver's trajectory is sufficiently away from the edge of the pool wall once they leave the board, reducing the likelihood of mishaps that can occur if the board were to extend less than this recommended distance.

Regulations and standards from organizations concerned with pool safety, like the National Association of Amusement Ride Safety Officials (NAARSO) or the American Society for Testing and Materials (ASTM), often specify this requirement to promote safe diving practices. Extending the diving board beyond the pool wall adequately supports safe diving activities, taking into account the varying skill levels of divers.
