A green lighted buoy with the number 3 typically indicates a navigational aid used in maritime settings. It signifies a safe channel for vessels, marking the starboard (right) side of the channel when approaching from the sea. The number on the buoy helps mariners identify their position and ensure safe navigation. In the United States, such buoys follow the IALA (International Association of Lighthouse Authorities) system, where even-numbered buoys are green and denote safe passage.

A red lighted buoy with a number 6 typically indicates a channel marker in maritime navigation. It signifies the port (left) side of the channel when entering from the sea, following the IALA (International Association of Lighthouse Authorities) buoyage system. The number 6 helps mariners identify their position relative to navigational charts. These buoys are essential for safe passage and navigation in coastal and inland waterways.
A boat should cruise between a green and red buoy. The red buoy will always be located on the right side of your boat. Red buoys will always mean , returning, red, and right. There will be a number on a red buoy that will give the chart location. The numbers will always be even.
It is bouy number 3 marking the channel into a harbor. Odd numbered bouys are normally green and on the left side as you enter the harbor.
When going upstream, a buoy with a number 5 and flashing green light indicates the presence of a dam ahead. The dam may be used to generate hydroelectric power or to provide water for irrigation, and can pose a danger to boats and other vessels.
Preferred channel markers are buoys showing red and green bands.
In Region B a "green can shaped buoy" stands for the edge of a channel on a boaters left side when entering from open sea or heading upstream, the opposite applies in Region A.
If it's "red right returning", it's green left returning and green right (starboard) going. That is to say, you pass it to the left (port) as you return to port.
In Region B a "green can shaped buoy" stands for the edge of a channel on a boaters left side when entering from open sea or heading upstream, the opposite applies in Region A.
A green square daymark buoy indicates a safe navigational point that is typically part of a system used to mark channels and hazards in waterways. It signifies that the buoy is a lateral marker, specifically indicating the starboard side of a channel when approaching from the sea. In the United States, it follows the "green right returning" rule, meaning boaters should keep the green buoy on their right when returning from the open water.
Do not pass between the buoy and the shore
