Final answer:
The vessel's position would be plotted as a fix, which is determined by taking a range and bearing to a known landmark or buoy.
Step-by-step explanation:
The vessel's position would be plotted as a c) Fix. A fix is the position determined by taking a range and bearing to a known landmark or buoy. It is a specific point on a chart that represents the vessel's location at a given time.
The other options can be defined as follows:
- a) Estimated position: An estimated position is calculated based on the vessel's course, speed, and time since the last fix.
- b) Dead reckoning position: Dead reckoning is the process of estimating a vessel's future position based on its present course and speed.
- d) Running fix: A running fix is a technique used to determine a vessel's position by taking fixes at two or more known landmarks or buoys.
