What do squares provide as daymarks?

Squares serve as daymarks in navigation primarily by providing directions and distances to various destinations. They are typically used to guide boaters safely through waterways by marking specific routes or landmarks. The design of a square daymark is easily recognizable, making it an effective way for mariners to ascertain their position and navigate towards their intended destination.

While daymarks can encompass a range of signaling functions, the specific role of squares is tied more closely to indicating routes rather than warnings about hazards, speed limits, or emergency services. By helping boaters understand where they are and how far they have to travel, square daymarks play an essential role in maintaining safe and efficient navigation on the water.
