- Use neap tides for easier current management
- Documentation
- Submit ETA updates via Portlink system every 6 hours
- Pre-clear dangerous goods declarations
- Equipment
- Ensure VHF radios meet Yangtze DSC requirements
- Verify AIS transponder compatibility
7. Critical Reminders
- Air draft calculations must use highest fixed point (typically radar mast)
- Pilot ladders must comply with SOLAS Regulation II-1/3.9
- All vessels must carry updated Yangtze River charts (scale 1:25,000)
