Speed Log
A speed log is a key navigation tool that measures a vessel’s speed through water or over ground. It provides accurate data to support safe navigation, efficient route planning, and fuel management.
Modern systems integrate with onboard navigation equipment to ensure reliable performance for all vessels.
Key Uses of Speed Log:
Accurate Speed Measurement
Provides real-time data for safe maneuvering and navigation.
Voyage Efficiency
Supports fuel optimization and time management by monitoring vessel performance.
System Integration
Works with GPS, ECDIS, and autopilot to enhance overall navigation accuracy.
Speed Log Features and Regulations:
- Measures speed through water (STW) or speed over ground (SOG).
- Required on many commercial vessels under IMO standards.
- Regular calibration and maintenance ensure consistent accuracy.
