About the Sextants

Proudly produced by artisan Patrick Lorho, each sextant comprises about 40 parts and provides accuracy within 100 meters. To improve durability and decrease weight, the instruments are made using aluminium instead of traditional heavy metals.

Production and Cost of Sextants

The production of a single sextant is labour-intensive, taking around 15 hours to complete. The cost of each sextant ranges from 1,200 to 1,500 euros, an investment reflective of the importance of reliable navigation for the French Navy.

The French Navy’s Commitment to Accuracy and Reliability

Operating a fleet of 140 vessels, the French Navy places a strong emphasis on accuracy and reliability. The reintroduction of sextants clearly demonstrates this commitment, as they provide a fail-safe method of navigation that is not subject to external interference.
