You plot a fix using three lines of position and find they intersect in a triangle. You should plot the position of the vessel __________.

🔍 Key Concepts

• Fix quality and what a “cocked hat” (triangle of position lines) indicates about your position • Which line of position is usually most reliable when objects differ in distance and bearing accuracy • How navigators treat the area of uncertainty when three LOPs don’t cross at a single point

💭 Think About

• Think about which of the three LOPs is likely to be the most accurate: the one from the nearest object, the farthest object, or doesn’t it matter? Why? • If your three LOPs form a small triangle, where is your vessel most likely to be in relation to the nearest aid or object used? • Consider practical navigation: if you must choose one line to trust most, how would its distance to you affect your confidence in it?

✅ Before You Answer

• Identify which LOP would generally have the least error (shortest range, clearest bearing) • Decide whether navigators assume the ship is equally likely to be anywhere inside the triangle or if some part of the triangle is favored • Ask: in standard piloting practice, where do textbooks say to place the fix when a “cocked hat” forms from three LOPs of differing reliability?
