What do crossing daymarks indicate?

Crossing daymarks are navigational aids that indicate the location of a channel or safe passage through navigable waters. When a crossing daymark is present, it serves as a guide for boaters to understand that the river channel is located on the opposite side of the daymark from where the boater is currently positioned. This helps navigators to adjust their course correctly while highlighting where to steer their vessels in relation to the daymark.

By recognizing that the channel is on the opposite side, boaters can avoid hazards and ensure safer navigation. This understanding is crucial, as it allows for effective route planning and helps prevent accidents in potentially dangerous or confined waterways.

In this context, other options do not provide the correct interpretation of what crossing daymarks signify in navigational terms, as they may suggest misleading information about the positioning of channels or hazards.
