Topic: dial down Posted: 17 Sep 13 at 8:11pm |
Or when a bit high on the starboard layline with a boat coming in on port. Bearing away to a collision course may persuade them not to tack in the zone, but cross ahead.

We seem to have some difference in understanding about the slang term 'dial down'.
A gentle bear away by a starboard tacker to gain an advantage isn't really a 'dial down'
Call that a dial down?
THIS is a dial down (45 to 55 seconds in)

Great example.
It's after the start so Call D6 is ON.
Note the following
@13 Y begins bearing away, aiming for B, and B begins bearing away to keep clear of Y.
@17 Y holds steady course, carefully above 90 degrees from true wind, B still bearing away.
@18 B stops bearing away and holds steady course, doing nothing to keep clear of Y.
@20 B again begins bearing away
@21 Y luffs hard in an attempt to avoid contact with B
@21.5 B luffs back towards Y
@23 contact.
Penalty Blue
What WAS B thinking?

Not sure that I read that the same way as Brass.
As B, on port bears away to pass astern of Y, Y bears away on to a collision course with B. At that point I can see nothing that B can do to avoid a collision except continue in a straight line and hope. As B passes ahead of Y she luffs towards a course at 180° to Yellow. A collision is still inevitable but it would have been gunwale to gunwale. At this point Y luffs hard and drives her port quarter in to B! For me Y broke rule 16.1 and rule 14. Penalty Yellow and they pay for damages. However that is from watching the video. The umpires obviously saw something else, or were influenced by the shouting.... And, being pedantic, the manoeuvre Ainslie carried out was not a "dial down" but "hunting" |

In fleet racing, I had always thought that as starboard boat you weren't allowed to alter course in either direction once a port tack boat was in the process of avoiding you? Am I just plain wrong on that?

What the rule says is that when a ROW boat changes course she must give a keep clear boat room to keep clear In addition rule 16.2 gives a further obligation to the starboard ROW boat when the keep clear port tack boat is sailing to pass astern. Starboard boat shall not change course if as a result the port tack boat would IMMEDIATELY need to change course to continue keeping clear.
So starboard boat can change course but within limits! |

Really hard with telephoto foreshortening, but I suspect that B luffed so that their stern would clear Y's bow, and wasn't expecting Y to turn so far. |

That's what I was brought up to understand too, in fact, 'hold your course' is popular, if seemingly pointless call from a port tacker in a club race. Hence why a big thank you is needed to those who've answered my OP and clarified it....
