Noon Sight Meaning in Sailing

A noon sight is a traditional navigation method used to find a boat latitude at sea. This technique involves measuring the exact height of the sun at its highest daily point. A navigator uses a specialized tool called a sextant to track the sun as it climbs. The sun reaches this peak height exactly at local apparent noon during the day. A sailor records this angle to calculate how far north or south the boat sits. This method provides a reliable way to check the boat position without using electronic sensors. Accurate timing is essential because even a small error changes the calculated location significantly. Mastering the noon sight allows a crew to navigate across entire oceans using only the sun.
