I am finding information online about a particular distress signal: that of a vessel displaying a code "Lima" flag, with a red ball below it. I have consulted Rule 37 and noted the distress signals of code flags November Charlie, or a square flag and ball (I have a copy of the USCG Navigation Rules). I cannot find any mention of a "Lima" flag and a red ball. Can you confirm this as a distress signal and, if so, what is the source?
You would be best to stick to the course materials and not use outside resources when studying for the final proctored exam.
With that said – If you see a vessel displaying the code flag “LIMA” below which is a red ball. The vessel is indicating that it is in distress. But again this is not material or a question that you will see covered in any of our course materials or on your final proctored exam.
We understand that you want to be thorough and not miss anything… Just as a reminder though – We wrote both the course and final exam. As long as you follow our program there will be no surprises when you come in to take your final exam.
