Can mariners manually adjust the GPS position of the ship?

• A. No, it is fixed automatically
• B. Yes, but only through external devices
• C. Yes, it is noted on the screen and recorded
• D. Only in emergency situations

Answer: (C)

The ability for mariners to manually adjust the GPS position of a ship is a feature that ensures flexibility and control over navigational data. When a mariner manually adjusts the position, this action is typically displayed on the electronic chart system's screen, allowing for real-time updates and visual confirmation of the changes made. Additionally, recording these adjustments is crucial for accountability and historical reference, which can be necessary for navigational safety and legal purposes. Thus, option C is correct as it captures both the visibility of the adjustment on the display and the significance of recording such changes. In contrast, options that imply limitations, such as being fixed automatically, only usable through external devices, or restricted to emergencies, overlook the practical functionality of ECDIS and do not fully recognize the mariner's involvement in navigation. The ability to manually intervene in positioning provides important situational awareness for mariners navigating through complex or changing environments. This control plays a vital role in ensuring safe and effective navigation.
