What is the recommended action if you see another ship while adrift?

Using visual signals to attract attention is the recommended action if you see another ship while adrift. When adrift, it's crucial to make your presence known to other vessels in the vicinity, as they may be able to assist you. Visual signals, such as waving arms, using reflective objects, or displaying flags, can effectively communicate your need for help. Other ships and their crew often look for such signals, and a well-executed visual signal can increase the likelihood of being spotted and rescued.

In contrast, ignoring the approaching ship would leave you in a precarious situation without assistance, while calling out for help may not be heard from a distance, diminishing your chances of rescue. Swimming towards the ship can also be dangerous, as it may lead to exhaustion and divert attention away from attracting the ship's crew to your location. Therefore, the best course of action is to use visual signals to ensure you are seen and can receive help.
