Under what condition must the master of a vessel render assistance to another vessel?

The requirement for the master of a vessel to render assistance to another vessel is conditional upon the feasibility of doing so without endangering their own vessel and crew. This principle is rooted in maritime law and emphasizes the importance of safety. The master must assess the situation and determine whether their vessel can assist without putting themselves, their crew, or their vessel in jeopardy.

In circumstances where rendering assistance would pose a serious threat to the safety of the vessel or crew, the law does not compel the master to act. Thus, the guiding principle is to balance the moral and legal obligation to assist with the practical considerations of safety.

Other options revolve around conditions that do not align with the established maritime law. For instance, the size of the vessel or visibility conditions are not primary factors dictating the obligation to assist. Additionally, orders from authorities do not override the master’s responsibility to ensure the safety of their own vessel first, as they must still assess the risks involved.
