How should divers safely enter the water from a boat?

The back roll entry is considered one of the safest methods for divers to enter the water from a boat. This technique allows divers to enter the water while keeping their gear secure and minimizing the risk of injury. When performing a back roll entry, divers can easily fall backward off the side of the boat, which helps to avoid impact with the boat or the surface of the water. Additionally, this method maintains the diver's orientation, making it easier to keep track of their gear and ensure a smooth transition into the water.

Other methods, such as jumping in without checking or diving headfirst, pose higher risks. These could lead to potential injuries or disorientation upon entering the water. Using a ladder to enter the water is also a safe option; however, it may not be feasible in all situations or for all types of dives. The back roll provides a balance of safety, efficiency, and ease of execution, making it a preferred technique for many divers.
