Buoy Types and Markings
- Can Buoys: Cylindrical-shaped, marked with green and odd numbers. Indicate left-side edge of the channel when entering from the ocean or going upstream.
- Nun Buoys: Cone-shaped, marked with red and even numbers. Indicate right-side edge of the channel under the same conditions as can buoys.
- Lighted Buoys: Include the characteristics of can and nun buoys, but equipped with a matching colored light for visibility.
Navigational Aids
- Daymarks: Permanent signs on posts in the water. Common designs include red triangles (like nun buoys) and green squares (like can buoys). May also be lighted for better visibility.
- Red Right Returning: A mnemonic aiding navigation, reminding mariners to keep red buoys on their right when returning from open waters or heading upstream.
Marker Shapes and Meanings
- Square Markers: Provide directions and informative messages to navigators.
- Diamond Markers: Serve as warnings for hazards and obstructions in the waterway.
- Circle Markers: Indicate controlled areas, such as restricted zones or regulated waters.
- Crossed Diamond Markers: Denote exclusion zones where passage is prohibited.
Safety and Mooring
- Safe Water Marker: White with red vertical stripes, signaling unobstructed water routes, marking mid-channels or fairways, and allowing passage on either side.
- Mooring Buoy: White with a blue horizontal band, designated for boat anchoring in marinas; legally permitted for tying up.
- Inland Waters Obstruction Marker: White with black vertical stripes, indicating navigational hazards; passing between these buoys and the nearest shoreline is prohibited.
