How does AIS help boating safety?

• A. Provides other vessels' identities, course, and speed to aid collision avoidance.
• B. Forecasts weather and wind conditions for the next hour.
• C. Shows depth measurements of the water.
• D. Only transmits your own vessel location.

Answer: (B)

AIS helps safety by providing other vessels' identities, course, and speed so you can judge potential collision risks and take early action. By receiving information such as each vessel’s name or MMSI, type, position, course over ground, and speed, you gain situational awareness of traffic around you. This lets you see which ships are on a crossing or head-on path, estimate how closely you’ll come together, and decide whether to adjust your speed or change course to stay well clear. This is especially crucial in crowded waterways, low visibility, or at night when you can’t rely on sight alone. AIS is about exchanging vessel information to improve safety; it doesn’t forecast weather, show water depth, or only transmit your own location. Use it alongside radar and chart plotting, and always follow the rules of the road.
