LOL!!! I knew it but I can't help myself but engage. A boat does not have to anticipate another boat's actions. Your arguement is just short of making that statement.... the F18 only needs to react to ARC's actions which it did. If ARC allows F18 to get close before fending off, then it also has to allow F18 the opportunity to respond to its actions. Good advice is to make your defense known early if you do not wish to be rolled.
