What is the primary disadvantage of relying solely on ECDIS for anchor watch?

• A. It may not detect anchor position accurately
• B. It uses outdated software
• C. It does not plot real-time data
• D. It requires constant manual input

Answer: (A)

Relying solely on ECDIS for anchor watch primarily presents the disadvantage of potential inaccuracies in detecting the anchor's position. ECDIS systems rely on GPS and their software algorithms to display the vessel's position and movement over time. However, there are inherent limitations in the accuracy of GPS, particularly in certain environmental conditions such as poor satellite visibility due to obstacles or weather. Additionally, while ECDIS is a sophisticated navigation tool, it may not always account for various factors that can influence a vessel’s movement at anchor, such as tidal changes, currents, and wind shifts, which may result in an inaccurate indication of the anchor's holding status. This reliance can be problematic during critical periods such as night, reduced visibility, or adverse weather conditions when visual checks of the anchor would provide essential data on the vessel’s position relative to the seabed and surrounding geographic features. Therefore, having a system solely reliant on ECDIS poses a significant risk that cannot be overlooked, emphasizing the need for integrating traditional methods and regular physical checks alongside electronic monitoring.
