The red light should be on the right side, or port side, of the boat. The green light should be on the left, or starboard, side of the boat.
A green sidelight must be visible to boats approaching from the right (starboard) side. This is part of the navigation rules that help mariners determine the direction of another vessel's movement. The green light indicates that the vessel is facing the observer's left side, meaning it is navigating towards them.
When operating a powerboat at night, your green sidelight must be visible to boats approaching from the starboard (right) side. This is crucial for signaling your position and direction of travel to other vessels. Additionally, the red sidelight on the port side must be visible to boats approaching from the port side. Together, these lights help ensure safe navigation and collision avoidance on the water.
When operating a powerboat at night, your red sidelight must be visible to boats approaching from the port (left) side. This is important for indicating your vessel's orientation and direction of travel to others. Additionally, your green sidelight on the starboard (right) side should be visible to boats approaching from the starboard side. Proper visibility of these lights helps prevent collisions and ensures safe navigation.
When operating a power boat at night, your red sidelight must be visible to boats approaching from your port side (left side). This is part of the navigation rules that dictate that vessels must display specific lights to indicate their direction and position to other boats. The red light, along with the green sidelight on the starboard (right) side, helps prevent collisions by signaling the boat's heading.
Starboard ( right side ) and it should be mounted so it is visible at 135 degrees .
The green sidelight on a boat is located on the starboard (right) side of the vessel when facing forward. It is typically mounted at the bow and is visible from the front and side of the boat. This light is part of the navigation lighting system and helps indicate the boat's direction to other vessels at night or in low visibility conditions.
A visible white light on another vessel indicates that it is approaching you head-on. This means you should also exhibit a white light to signify that your vessel is also approaching head-on.
You are approaching the stern of another vessel and may be overtaking it
You are approaching the starboard side of another vessel
You are approaching the port side of another vessel
In maritime navigation, visible white lights indicate a vessel's masthead light or stern light, while green lights signify the starboard side of a vessel. When encountering another vessel in darkness, if you see a green light, it means the vessel is approaching from your right side. Conversely, a visible white light could suggest that you are either approaching the stern of the vessel or that it is facing you. Understanding these light signals helps in determining the direction and movement of nearby vessels to avoid collisions.
If two boats are approaching from the port (left) side, and you have a red side light, it means they are on a collision course with your vessel. You should take immediate action to avoid a collision by altering your course or speed.
