When planning to dive, what is the standard spacing to maintain under a vessel?

Maintaining a spacing of 6 feet under a vessel while diving is crucial for safety. This distance allows for adequate clearance between divers and hull surfaces, ensuring that divers are not inadvertently struck or trapped. Additionally, the 6-foot spacing helps avoid interference with the vessel's operations and decreases the risk of entanglement with mooring lines or underwater structures associated with the vessel.

A clearance of 6 feet is generally regarded as sufficient to account for a diver's upward movement and equipment, ensuring that all divers can operate freely without the risk of collision. This spacing allows dive supervisors to keep a clear visual on all divers while they are under or adjacent to the vessel, enhancing overall safety and coordination during the dive operation.
