What is the recommended ascent method to surface at the boat?

Ascending along the anchor line is recommended because it provides a controlled and safe method for divers to return to the surface. This approach allows divers to maintain a constant reference point, which helps prevent disorientation during the ascent. The anchor line serves as a guide, ensuring that divers ascend to the surface vertically, reducing the risk of rapid ascents that could lead to decompression sickness.

Using the anchor line also enables divers to utilize it for safety stops as necessary, particularly during deeper dives. This pause allows nitrogen to off-gas safely from the body, further reducing the risk of decompression issues. Additionally, ascending along the line allows immediate communication and visual confirmation with the boat crew, enhancing safety during the return to the surface.
