The Lateral Buoyage System
The Lateral Navigation System is key for safe water travel. Known as the “red right returning” system, it helps boaters know where to go. When returning from the sea, you’ll find red, even-numbered markers on your starboard side. On the port side, you will see green, odd-numbered markers. These markers are essential. They show the edges of safe water channels and help guide you in the right direction without a compass. Buoys can be various shapes. Port-side aids are often can-shaped while starboard-side aids are cone-shaped or nun-shaped. A special type, the bifurcation buoy, has horizontal red and green bands. This buoy shows where a channel splits, with the top band indicating the preferred route.
Starboard Markers
Starboard markers are easy to spot. They’re red and marked with even numbers. Keep them on your starboard side when going upstream. They have a conical shape, pointed at the top, and may flash a light at night. In Region A of the IALA system, these red buoys show the starboard side on return from the sea. They are vital for guiding boat operators. These markers help avoid collisions and chart a safe course. Recognizing starboard markers by color and shape is crucial for boating safety.
Port Markers
Port markers, or port-hand buoys, are green with odd numbers. They guide you along the left side of the waterway when traveling upstream. These buoys look like a can or drum and might have a flashing green light. This helps navigators see them better. As you move upstream, the numbers on these port markers will go up. This helps boaters stay oriented on the water. Keep these buoys on your left to stay clear of hazards. In the lateral navigation system, port-side buoys are crucial. They ensure safe passage on the channel’s left side to prevent collisions with obstacles.
