Local magnetic disturbances of up to how many degrees have been noted from Cape Henry to Currituck Beach Light?

🔍 Key Concepts

• Local magnetic disturbance as described in U.S. Coast Pilot and on nautical charts • Difference between normal variation/deviation and special caution notes about abnormal compass behavior • Geographic area: Cape Henry to Currituck Beach Light on the U.S. East Coast

💭 Think About

• Check how Coast Pilots or chart notes typically describe the maximum local magnetic disturbance in degrees for specific coastal stretches • Think about whether ordinary small errors (like slight deviation) would require a special printed warning, or only larger, unusual values • Consider which of the choices seems significant enough that a navigator should clearly be alerted to it in a sailing direction or chart note

✅ Before You Answer

• Verify what the U.S. Coast Pilot or similar publication says for the stretch from Cape Henry to Currituck Beach Light • Confirm that you are looking at a note about local magnetic disturbance, not just normal annual change of variation • Make sure the number you choose matches a value that would reasonably be highlighted as a maximum error that could affect safe navigation
