We're nearly there FDUB I was trying to post a short response which was why it came out mean, here is your problem you say he had room so you hit him as you luffed him. You have now broken the main rule of seamanship you collided when you could have avoided, the sailor clearly had no space or would not have hit the boat inside him while you were hitting him this proves the no space rule. You should have given room, flew your red flag and demanded redress in the room after the race, you would then call your witnesses that would defend your protest, the other skippers would have called their witnesses, regardless of how this case came out there would have been a safe race with no damage to boats. I would be very surprised if your protest was upheld as I can't see the new catamaran sailor who yelled starboard when last in the 3 boat circle would be well equipped to work out how much space is enough as opposed to the 3 experienced sailors he forced to collide. I think it's wonderful that you are enthusiastic about cat sailing and would encourage you to consider sailing aggressively but courteously within the rules so that you are welcomed and encouraged on the beach instead of the alternative. Just acknowlege you were wrong by forcing a collision without making any excuses and you go back to rockstar
