Zenith Navigation

WikiTagsWikiShare


BoatWiki - Definitions

Definition


A zenith can be defined in navigational terms as the point in the celestial sphere directly above an observer. It is a factor used in determining latitude and longitude with a sextant.

Meaning


Aids to navigation are crucial for safety at sea and the sextant is a timeless device long utilized for such purposes.


Context

Although sextants are still employed and even required in some commercial circumstances, their function has been broadly displaced by electronic global positioning systems (GPS). However, many offshore boaters still maintain such devices, especialy for emergency situations.

Conclusion


The terms zenith and sextant may not have much meaning for the typical boater but becoming familiar with these will enhance overall seamanship capabilities.

Please assist your fellow boaters by wiki-sharing any comments or experiences regarding this subject.
