What Is the Transas Navi-Sailor 4000?

The Navi-Sailor 4000 is an IMO-approved ECDIS system that integrates navigation charts and vessel sensor data into a single operational platform.

The system continuously receives information from:

• GPS / DGPS
• Gyro Compass
• Doppler Speed Log
• AIS
• Radar
• Echo Sounder
• Autopilot
• Voyage Data Recorder (VDR)

This information is displayed directly on electronic navigation charts, allowing navigators to monitor vessel position and voyage progress in real time.
