Like they say, you can't make this stuff up!
Yes, we'll, I don't quite know what you mean by saying it. But it's not remarkable. Racing around the cans on a Saturday afternoon these occurrences happen all the time... Last race series I was in (Antigua race week) there was a protest in our division after EVERY race. And it was a cruising division! And each day about 20 protests over all.
Half the reason is that old wankers on these forums denigrate the new technology like AIS preferring paper, sextants and baring compasses. Quite obviously if both boats had AIS this situation would not have occurred.
But it's not extraordinary. All ships have it, all fishing vessels that go well off shore have it... It's only $500 for a transponder.... But it's the cruisers who are the last up takers of it!
If you don't have AIS buy one.
