What is the content of the rule concerning the 'Conduct of vessels in restricted visibility'?

The content of the rule concerning the 'Conduct of vessels in restricted visibility' falls under Rule 19 of the COLREGs (International Regulations for Preventing Collisions at Sea). This rule outlines specific actions that vessels should take when they find themselves in conditions where visibility is significantly reduced, such as fog or heavy rain.

In these situations, vessels must navigate with extreme caution and ensure that they are prepared to take the necessary actions to avoid collisions. Rule 19 emphasizes the importance of safe speed, the need to assess the risk of collision, and the requirement to take appropriate measures to avoid collisions as necessary. It also mentions that vessels equipped to do so must use sound signals to communicate their presence to others in proximity.

Understanding Rule 19 is crucial for any Officer of the Watch, as it guides the decision-making process during low-visibility circumstances, ensuring that safety remains the top priority in maritime operations.
