What are “navigation aids”?

Navigation aids are crucial components for safe boating and navigation on waters. They primarily consist of buoys and markers that offer essential information to mariners about safe routes, hazards, and other navigational details. These aids signal safe areas, warn of dangers, and provide guidance on channels and approaches to harbors. Their purpose is to enhance situational awareness and help boaters navigate effectively, particularly in unfamiliar waters.

The other options describe different tools or equipment that serve unrelated purposes. Fishing gear is primarily used for catching fish rather than aiding navigation. Devices for weather forecasting help with predicting environmental conditions but do not provide navigation assistance. Equipment for underwater exploration is focused on studying aquatic life or geography, rather than guiding safe passage on the surface of the water. Thus, option B accurately captures the essence of navigation aids.
