Tips for the dark

Navigation aids such as chart machines and radar can help, but the visual picture and what we see around us change significantly when it gets dark or visibility os reduced.

It is also challenging if a vessel does not have lanterns/lights, or when the lights blend in with the background ligthing from the shore.

Make sure you have your own lanterns turned on, execise caution and keep a distance from other vessels. If you are unsure whether you are seen, do what you can to avoid the risk of an accident. Remember that it can take at least 30 minutes to achieve good night vision.

Ensure that the boat you are on does not have lights or obstacles that can obstruct lanterns or otherwise distract safe navigation for other vessels. It can be helpful to view your own vessel from a bird's eye perspective and consider how your vessel is observed by others.

Read the Rules of the Road at Sea

Requirements for lanterns for large and small vessels, are found in Part C of the Rules of the Road at Sea.

It is important to note that even small vessels must have lights and exercise caution as described in rule no. 43.

A simple lantern with white light can be difficult for other vessels to observe. Therefore, you must stay well clear to avoid dangerous situations and accidents.
