🔍 Key Concepts

• Safe water (mid-channel) marks in the U.S. Aids to Navigation System (vertical red and white stripes, with a distinct topmark/shape) • Difference between lateral marks (port and starboard channel sides) and safe water/fairway marks (water all around) • How the shape or topmark of a buoy/daymark tells you its function, not just its color

💭 Think About

• Ask yourself: which of these shapes suggests a mark that is safe to pass on either side, rather than marking just the left or right side of the channel? • Think about what shapes you normally associate with port side (odd/green) and starboard side (even/red) daymarks and eliminate those from the choices. • Which symbol here most closely matches the traditional chart symbol/topmark used for a mid-channel or fairway mark rather than a lateral mark or a regulatory sign?

✅ Before You Answer

• Be sure you can picture the standard safe water mark: its color pattern and its spherical/topmark style symbol on charts. • Eliminate the shapes you know are used for port (square/can) and starboard (triangle/nun) lateral marks. • Confirm that the remaining choice matches the idea of safe water all around / fairway rather than a regulatory warning, danger, or special mark.
