How does the captain of an old sailing ship see where he is going?
In the days before GPS and electronic navigation, captains of sailing ships relied on a variety of methods to determine their location and course. These methods included:
- Dead reckoning: This method involves keeping track of the ship's speed and direction over time to estimate its current position.
- Celestial navigation: This method involves using the positions of the sun, moon, and stars to calculate the ship's latitude and longitude.
- Coastal navigation: This method involves using landmarks and other features of the coastline to determine the ship's position.
- Lead line: This method involves dropping a weighted line overboard to measure the depth of the water, which can provide clues to the ship's location.
- Logbook: Captains kept a logbook to record the ship's daily progress, including its speed, direction, and weather conditions. By referring to the logbook, captains could track the ship's movements and make course corrections as needed.
