Reply to comment by Grimour in TIL about Deaf lifeguard Leroy Colombo, who overcame childhood paralysis through swimming and saved a record-breaking 900+ lives during his career. His swimming talent and use of sight rather than sound to identify drowning swimmers allowed him to save people other lifeguards would have missed. by lemontreelemur

For what it’s worth. Turning off your own radar doesn’t stop other boats from seeing you with their radar. Their radar sends radio waves out, then measures the time it takes until it detects the reflection.

You are thinking of Automatic Identification System. I’m not sure what the laws are about turning one off if you have one, but you aren’t required by law to have one if you are under 65ft in the US. IDK about china.
