Due to current stay-at-home orders and uncertainty on when we will be able to resume classes the decision has been made to move the Summer 2020 Celestial Navigation Course online. The class will be synchronous learning in real-time with the instructor leading the class and students able participate and ask questions in a Zoom environment. Registered students will receive more information with regards to accessing the course, materials etc. Field trips will still take places as scheduled.
Prerequisite: Coastal Navigation I or Equivalent
We have come to rely on satellites and electronic navigation, but the complete seaman is still adept at the art of celestial navigation. This class is devoted to the basics of celestial navigation and principal trans-oceanic navigational skills. You will learn to navigate utilizing the sun, sextant, chronometer and tables.
You will learn to calculate sailings to determine the best trans-oceanic route to take, use and read a sextant to measure altitude of the sun & stars, take noon sights, and take
lateral sights(Azimuth) to check your vessel’s compass deviation. Then you will take the sighting information, and learn how to translate that reading into a line of position.
Six class meetings and two field trips to practice hands-on use of the sextant and chronometer.
Min 5 /Max 10 students.
