OK: Say you are heading to a gate close behind two boats that you are very close to in the regatta. Those two go into thier roundings and there is lots of contact and no one calls protest. You know there was a foul and if either one of those boats has to do a circle you would pull ahead of them in the regatta (maybe getting you a top 5 or 10). I have seen this happen many times and usually someone near by will start yelling that someone owes a circle. Do you, as the one closest, who saw it happen but is unsure who was wrong then protest both under rule 18?, rule 2? This could cause resentment. Thoughts??
