You are making good a course of 060°T at a speed of 13.5 knots. At 1855 Block Island North Light bears 086°T; at 1910 Block Island North Light bears 108°T; and at 1930 the same light bears 184°T. Which statement is TRUE about your 1930 running fix position?
• Running fix using three bearings at different times to the same object • Transferring earlier lines of position (LOPs) along your dead reckoning (DR) track using speed and time • Reading chart symbols and areas near Block Island North Light (depth curves, bottom type, cables, and fishing/lobstering areas)
• How do you convert the time between bearings into distance run along your DR course at 13.5 knots, and how does that help you shift earlier LOPs to 1930? • Once you have your 1930 running fix plotted, what chart features lie directly under or immediately adjacent to that position? • Which of the answer choices describes a specific charted feature that could be positively confirmed at a single point (your running fix), rather than a broad regional description?
• Carefully compute distance run between 1855–1910 and 1910–1930 using ( \text{Distance} = \frac{\text{Speed (kn)}}{60} \times \text{Minutes} ). • Make sure each earlier bearing LOP is correctly advanced along 060°T by the distance run to 1930 before taking the intersection as your running fix. • On the chart, verify exactly what lies at that intersection: check depth curves, bottom composition labels, cable area boundaries, and the meaning of the wavy magenta lines.
