Which statement defines a Visual Fix?

Which statement defines a Visual Fix?

• A. GPS, Intersection of 3 or More Radar Ranges, or a Combination of Visual LOPs and Radar Ranges Obtained From Simultaneous Observations
• B. Limited Objects Are Available for Taking LOPs, and the Vessel Remains on a Constant Course
• C. Common Intersection of Three or More LOPs at a Common Point Obtained From Simultaneous Observations
• D. Starting Point, Course & Speed, Time & Distance

Answer: (C)

A visual fix is established when several lines of position from visual observations cross at a single point on the chart. Each line of position represents where the vessel could be given a bearing or sight to a known landmark, star, or other navigational reference. Taking three or more of these observations simultaneously is essential because the vessel is moving; simultaneous observations ensure all lines pertain to the same moment in time. When the lines intersect at a common point, that intersection defines the vessel’s position. This is distinct from fixes that rely on radar ranges, GPS data, or dead reckoning methods, which involve different sources or methods of position determination.
