While our navigational equipment most often is used for commercial and military navigation purposes, the hobby sailor or yachtsman also can make use of these tools. In fact, rather than simply relying on electronic equipment such as RADAR, SonAR and depth sensors, it can be smart how to use both electronic and manual navigation equipment, including the following.

1. Navigational Sextants

Sextants have been a sailor’s tool for hundreds of years, and these devices can calculate the angle between two visible objects. A sextant includes a telescope and several mirrors as well as an arc and micrometer. The person holding the sextant will use the device to measure the altitude of a star, the moon or another celestial body in relation to the horizon.

With a bit of practice, you can learn to use a sextant to determine your geographic position in terms of latitude and longitude. While it might seem easier to simply use a GPS device, being able to calculate your location without any type of electronic aid is always an excellent idea, particularly if you enjoy longer voyages at sea.
