4.8.2 Navigation lights

The rules relevant to the navigation lights must be observed from sunset to dawn and during this period no other lights must be visible except the lights that cannot be exchanged for those specified in this manual.
Although the lighting system is preset by the Manufacturers, the Owner/Captain has the responsibility for the observance of the local rules.
Please note that the local and international rules relevant to lighting can slightly vary, we suggest therefore to gather information about the local rules of your area.
Night navigation requires more precaution. All rules are applicable but apart from the right of course, it is advisable to slow down and to keep the proper distance from other boats.
It is a good rule to remember that bright lights reduce visibility at night.
