The red sidelight on a powerboat should be visible from the front and from the left (port side).
There are a number of different lights that must be used on a boat when it is nighttime, and these are:
These lights are also known as combination lights and are red and green. The red sidelight should be visible from the port side and the green light indicates the right side (the starboard).
The stern light is visible from behind the vessel.
The masthead light is a white light that shines forwards and to both sides of the vessel. All powered vessels are required to use this light.
This light is an important light that is used to combine the masthead light and the stern light. It should be used on all vessels over 39.4 feet in length and is classed as an anchor light when the sidelights are not in use. This single light is visible to all vessels from all directions.
There are certain rules that are required to be followed by all boats that travel at nighttime and these include the rules that govern the overtaking and passing of other vessels.
When a white light is the only light visible, it is possible to pass the other boat from either side. When the lights visible are white and green, the boat you are in is classed as the stand on vessel and you are able to pass vigilantly.
When a red light and a white light are visible, the boat you are in must give way to the other vessel. If only a red light, or a green light is visible, the vessel you are in must always give way.
