What is the term for the calculated space allowed for diving between a ship and a pier?

The term describing the calculated space allowed for diving between a ship and a pier is typically around 6 feet. This distance is important as it provides a sufficient buffer to ensure that divers can safely enter and exit the water without risk of getting caught or trapped between the hull of the vessel and the structure of the pier. Maintaining this space helps to account for potential shifts in water levels, as well as the movement of the ship, which can create hazards if divers are too close. By adhering to a 6-foot guideline, safety is prioritized, allowing for a safer workspace for divers to conduct their activities without undue risk of entanglement or collision with the ship or pier.
