i know that during some protests there is alot of speculation as to "did you actualy call protest", and on the protest form there is a question "did you fly a protest flag"... so i figure just get one for the hell of it.
I have a protest flag, but i only use it if some one doesn't do their circles even after i yell at them. I know that you don't need one, but it is one of the questions that they tend to ask you when you are in a protest, so it is nice to have one just in cace and to prove that you did protest.
49208 has it right. You do not require them. Flying it proves nothing. The only thing valid is hailing protest. While you reach for your protest flag I will gain 2 more boatlengths on you. See ya at the bar.
The question is about a protest flag. As being an on water judge and jury, it is the length of the boat that defines the requirement for having a protest flag. Where you store it is up to you, but as one reply indicated, he will gain 2 boats lengths while you grap it. The flag must be a flag, there are a number of cases that define what the flag should be like, from size and shape.
Having said that for a protest to be valid, the word "protest" MUST be used. It is a requirement as per the rules. "Do your turns" does not count. Having hailed at the earliest opportunity is one of the test for a valid protest.
