Compass Calibration
Valnau Superyacht Services provides professional magnetic compass calibration to ensure accurate heading information and safe navigation. This service is essential after refits, equipment upgrades, structural modifications or changes in onboard electrical and metallic components that may affect magnetic deviation.
Accurate compass calibration is critical for compliance with maritime regulations, class requirements and safe vessel operation, particularly on superyachts operating complex navigation systems.
Why Compass Calibration Is Essential
Magnetic interference caused by onboard equipment, structural changes or accumulated deviation over time can lead to inaccurate compass readings. Regular calibration ensures:
Reliable heading reference
Compliance with flag state and class requirements
Safe navigation in restricted or low-visibility conditions
Proper integration with navigation and autopilot systems
Our Calibration Process
Deviation Assessment & Planning
Initial assessment of the vessel’s magnetic environment, identifying potential sources of deviation and defining the calibration scope based on vessel type, size and operational profile.
Onboard Compass Calibration
Calibration carried out onboard using established deviation correction procedures, adjusting compensators and verifying compass accuracy across multiple headings under real operating conditions.
Verification & Documentation
Final verification of compass accuracy and preparation of clear calibration records, deviation cards and technical documentation suitable for captains, surveyors and inspections.
Reliable compass data for safe and confident navigation.
Compass calibration requires experience, precision and a solid understanding of vessel magnetic behaviour. Our team combines hands-on onboard expertise with proven calibration methodologies to deliver accurate and dependable results on superyachts operating worldwide.
We operate efficiently onboard and in shipyard environments, ensuring minimal disruption while delivering calibration services that support safe navigation, regulatory compliance and confident decision-making.
