What is the approximate geographic range of Race Rock Light, NY, if your height of eye is 27 feet (8.2 meters)? Refer to "Reprints from the LIGHT LISTS AND COAST PILOTS".
• Geographic range vs. luminous range – know which one the question is asking for • How to use the Light List table for height of light and height of eye to find geographic range • The effect of height of eye (observer) on the maximum visible distance of a light
• Look up Race Rock Light in the Light List: what is the height of the light above water, and how is geographic range determined from that? • How do you combine the distance to the horizon from the light and from your eye height to get the total geographic range? • Which of the answer choices best matches the sum of those two distances when rounded to the nearest tenth of a nautical mile?
• Be sure you are using geographic range tables, NOT luminous range or nominal range tables • Confirm you are using the correct height of light for Race Rock Light from the reprint, and your height of eye = 27 ft (8.2 m) • After adding the two ranges, check that your final value is properly rounded before comparing with the multiple‑choice options
