  • I think we all agree that RobO's historical notes are incredibly informative. So, we don't need a new def for tack(v) if it is only going to be used in R13 and R20 one or both of which might require slightly different treatments.

    Re R20: My view is that 'room' impies the act of 'luffing' to HTW phase of the manoeuvre. After we have passed HTW we have changed tack and started the 'tacking' phase which ends when a close-hauled course is reached. This could be better described in R20.

    That said, it is interesting to note the 'patterns' applied (or not applied) to the rules of Part C. Rules 18 and 19 both start with "When Rule XX Applies" whereas R20 does not. Furthermore, the second sentece of R20.1 and related subclauses effectively describe when R20 applies albeit in the negative (note the "unless") ... which is I am sure as confusing as hell to most punters ;-)

    So, maybe we should create a new 20.1 titled "When Rule 20 Applies" based on the 'unless' bit of R20.1.

    This would of course mean that existing rules 20.1 through to 20.4 would need to be renumberd which is a pain for anyone responsible for writing SIs!

    As far as creating a new 'case' is concerned, I disagree. It is my understanding that the purpose of the Case Book is to determine how the interaction of multiple rules should be interpreted in a given situation. That is to say, if a case involves just one rule and its interpretation then that rule probably needs to be fixed!

    The following state diagram might help with some of what I have said previously:

    Please note that the each box represents a 'state' that exists for more than just a moment. Below the line in each box is the 'event' which initiates the transition from one state to the next.

  • On a beat to windward, R 18 rarely applies and certainly does not in this case.
    Focus on the rules in section A.

    If I was red I would have delayed my first tack to ensure I could push green up in to the mark and force them to bail.

  • I am struggling with the OP's diagram because while blue and green slow through their tack red accellerates and gains about one boat-length in the process.

    Green had tacked and was building speed. She was then on a collision course with red so ducked a little as required by R 15 which would have allowed her to accelerate even more. I can see no way red would have exited their tack clear ahead of green.

    So, what came first here, the facts or the diagram? Because, they are not consistent.

    BTW, I am presuming one-design racing here (or similar) because nothing has been mentioned of vastly different tacking characteristics.

  • The RYA position only follows good sense and general sailing practice.
    A flag chan be furled on the backstay or shroud, and secured with tape. This by just leaning over it can be unfurled in seconds.
    The teas then is relative to this. So for instance if you have to go belw toa locket to get the fag and this takes 30 seconds, relative to the above it is slower so not at the first reasonable opportunity.

    The rest is relative to a prompt response not quick because of the relative location of the flag on a particular boat.

    Yes on Validity, if all is in order on the protest form little need be asked unless it is raised by the other boat. Asking if there is any complaint identifies to issue so you cam move on.

    On appeal generally if a boat has not challenged the validity of the flag or hail initially at the hearing, then there is no act or omission or is partly that boats fault for not raising it. No redress, and the reasons just follow the rules.

    If not it starts to appear in all complaints, Reopenings and appeals.

  • Hey Jerry .. I started a new thread. Lemme know what u think of how I approached it.
