Wouter, I am not sure if you purposely missread other peoples statements so that you can then shout that people do not know the rules, or if you just take things up the wrong way. I was answering the above quote and trying to show that you must take resposibility for your actions and not say something like "OK maybe I am in the wrong, but you have to let me pass you anyway because I might capsize my boat"
I was talking about 2 similar cats racing downwind. One is maybe 5 to 10 boatlengths behind the other and slightly to windward. The first cat sees the second one getting a gust and coming up fast behind. The first cat will luff up to stop the second overtaking to windward (It is called racing you know). If the second cat decides to commit to passing the first to windward and gets a stronger gust, which might capsize him because of his spinnaker, the first does not have to bear away to let him pass safely. The overtaking boat must stay clear and not get himself into that situation. It is very much outside "the bounds of good sportsmanship and the spirit of yacht racing" to try and win a race because you know that, even though you are in the wrong, a competitor will back off and let you pass to avoid an accident caused by your bullying and disregard for the rules.
It may not be Nascar, but it is similar to Formula 1. You do not dive down the inside and expect the driver you are trying to overtake to get out of your way just because you missjudged your braking.
