How many sides do red daymarks have?

Red daymarks are navigational aids often used to mark channels, shoals, or other significant features in waterways. They typically appear in a triangular shape, meaning they are designed with three sides. This specific configuration is used to ensure that they are easily recognizable to mariners, particularly in comparison to other navigational markers, which may have different shapes and colors. The triangular shape, with its pointed top, assists in indicating direction, making it an effective visual cue for boaters. Therefore, the choice reflecting that red daymarks have three sides aligns with the standard characteristics used for navigational purposes.
