For self-propelled vessels of 1500 or more, what must the owner or master ensure?

For self-propelled vessels of 1500 gross tons or more, the owner or master has several critical responsibilities to ensure the safe and effective operation of the vessel.

Firstly, maintaining a constantly manned wheelhouse is important for navigation and safety. This allows for immediate response to any potential hazards or changes in operating conditions in real-time. Having personnel in the wheelhouse ensures that the vessel can be navigated safely at all times.

Secondly, the requirement to fix the vessel's position is vital for safe navigation. Knowing the precise location of the vessel allows the crew to avoid collisions, groundings, and other navigational hazards.

Lastly, ensuring that all crew members are competent to perform their duties is essential for overall vessel safety and functionality. Competent crew can respond efficiently to emergencies, follow operational protocols, and maintain the vessel's equipment in good working condition.

When all these factors are considered together, it is clear that a combination of constant monitoring, effective navigation practices, and crew competence is crucial for the safe operation of larger self-propelled vessels. Therefore, the owner's or master's responsibility encompasses all these aspects, making the correct choice comprehensive and vital for maritime safety.
