Rules & Printing problems
Hi,
Norm:
Best
compliment my site has ever had! Thanks! Will answer in red
below. Best regards,
Uncle
Al (W3854)
Rules
question: All experienced racers should know that in a crossing
situation between a boat sailing downwind and a boat sailing upwind, both
boats on the same tack, the leeward boat has the right of way.
Unfortunately I can't find this in the rules. Rule 11 comes close but
has the stipulation "overlapped" which doesn't apply to this
situation. Rule 12 covers "not overlapped" but gets into
clear ahead/clear astern. Very confusing, please explain.
A
beautiful question that required serious thinking - just the kind I love!!
I'll be posting this question as Case #65 of my quiz if you don't mind. To
attack your question, I ended up working backwards from the assumption that
Rule 11 must apply since 12 definitely will not address the situation (an
example of which I have diagrammed below - boats images courtesy of Dave
Dellenbaugh's Speed'n'Smarts!)
..
..
Which
brings us to the definitions involved:
Clear
Astern and Clear Ahead; Overlap One boat is clear astern
of another when her hull and equipment in normal position are behind a line
abeam from the aftermost point of the other boat's hull and equipment in
normal position. The other boat is clear ahead. They overlap when neither
is clear astern or when a boat between them overlaps both. These terms do
not apply to boats on opposite tacks unless rule 18 applies.
Leeward
and Windward A boat's leeward side is the side that is or, when
she is head to wind, was away from the wind. However, when sailing by the
lee or directly downwind, her leeward side is the side on which her
mainsail lies. The other side is her windward side. When two boats on the
same tack overlap, the one on the leeward side of the other is the leeward
boat. The other is the windward boat.
Looking
at the definition regarding overlap, we can apply the first sentence (about
the "line abeam...) as follows:
Is Windward
clear astern?
- No,
because her hull and equipment are not astern of the line abeam from Leeward's
aftermost point.
Is Leeward
clear astern?
- No, because
her hull and equipment are not astern of the line abeam from Windward's
aftermost point.
Ergo,
the first part of sentence #2 applies: "They overlap when neither is
clear astern..."
So,
they overlap and thus Rule 11 applies.
It
remains to demonstrate that Leeward is indeed the leeward
boat.
The
definition says: "When two boats on the same tack overlap, the
one on the leeward side of the other is the leeward boat. The other is the
windward boat."
This
is a less obvious example than the usual situation where boats are going in
more or less the same direction, but by extending the centre line of either
boat forward, we find Leeward on the leeward side of Windward,
and vice versa.
Printing
problem. Would like to point out a problem with printing out your
great stuff. Your pages are so wide that they don't print
correctly in landscape. For example in your "Brief Synopsis of
the Racing Rules" several characters are missing when printed in
landscape even when I set the margins to .5 inches. Some of the other
sections print all the characters but it would be better to have larger
margins so you could use a 3-hole punch.
I'd
have to do serious re-formatting on the web site and am not sure exactly
what size would work. What I have done is re-formatted the Racing
Rules Synopsis in Word 97 to fit onto one landscape-oriented page with
.5" margins. This - and its images - is attached. As for any of the
other material, I might suggest highlighting any text that is not part of
an image, copying it and then pasting it into the word processing programme
of your choice - in my case Word 97. Similarly, you can right click any
image, save it in an image processing programme (I use Paint Shop Pro) and
then you can play with it (re-size, etc.) as required. This way you can set
up what you copy to look exactly as you want it, with appropriate margins,
etc.
Hope
this will help. Best regards, Uncle Al (W3854)
