Which rule covers the signals of vessels in distress under COLREGs?

The correct choice addresses the signals of vessels in distress as outlined in the COLREGs, specifically referencing Rule 37. This rule describes the actions that vessels must take to signal distress and does so by outlining specific distress signals. These signals include visual signals like the raising of a flag or the use of pyrotechnics, as well as sound signals. The purpose of these signals is to ensure that vessels in distress can communicate their situation effectively and draw attention to their needs for assistance.

Understanding the significance of Rule 37 is crucial for maritime safety, as it provides clear guidance on how to signal distress, thereby allowing for a coordinated response from nearby vessels and rescue services. This is vital in emergency situations, ensuring that appropriate help can be deployed efficiently. Distress signals are a fundamental aspect of maritime operations, and knowledge of these rules enhances the safety of all vessels at sea.
