What is the Daybeacon definition?

• A. Fixed marker, triangular or square
• B. Yellow, marks features or zones
• C. Red/white vertical stripes, mid-channel
• D. Conical, red, starboard side

Answer: (A)

Daybeacons are fixed markers used for daytime navigation. They stay in one place and do not rely on lights. The defining feature is their shape—triangular or square—so mariners can recognize the marker during daylight even without illumination. This distinguishes them from marks that depend on color patterns or buoy shapes. For example, yellow marks indicate features or zones, red/white vertical stripes mark different kinds of navigation information, and a conical red buoy is a buoy that marks a channel side. The fixed marker with a triangular or square daymark is the telltale sign of a Daybeacon.
