Other Non-Lateral Markers
Safe Water Markers: These are white with red vertical stripes and indicate unobstructed water on all sides. They mark mid-channels or fairways and may be passed on either side.
Mooring Buoys: These are white with a blue horizontal band. They usually are placed in marinas and other areas where boats are allowed to anchor. These are the only buoys you may tie up to legally.
Inland Waters Obstruction Markers: These are white with black vertical stripes and indicate an obstruction to navigation. You should not pass between these buoys and the nearest shore.
