What should a vessel do if it is unable to maintain its position?

When a vessel is unable to maintain its position and is in a situation of peril, using distress signals to indicate trouble is essential. Distress signals are internationally recognized signals that inform nearby vessels and search and rescue authorities that the vessel is in urgent need of assistance. By displaying appropriate distress signals, such as the international distress flag (the rectangular flag with a ball above and below), or using sound signals, the vessel communicates its situation more clearly to others in the vicinity, thereby increasing the chances of receiving timely help.

In contrast, other options may not effectively communicate the urgent need for assistance. Displaying a "vessel at anchor" signal does not indicate distress, as this signal merely informs other vessels that the vessel is anchored and does not require help. Launching boats to search the area could be an action taken to find help, but it does not directly signal the vessel's distress status. Lastly, sailing away from the area could further complicate rescue efforts and might lead the vessel into a more dangerous situation. Therefore, using distress signals is the most appropriate action when a vessel is in peril and unable to maintain its position.
