DEFINITIONS A term used as stated below is shown
in italic type or, in preambles, in bold italic
type. Abandon A race that a race committee or
protest committee abandons is void but may be
resailed. 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
boats hull and equipment in normal position. The
other boat is clear ahead. They overlap when
neither is clear astern. However, they also
overlap when a boat between them overlaps both.
These terms always apply to boats on the same
tack. They do not apply to boats on opposite
tacks unless rule 18 applies or both boats are
sailing more than ninety degrees from the true
wind. Fetching A boat is fetching a mark when
she is in a position to pass to windward of it
and leave it on the required side without
changing tack. Finish A boat finishes when any
part of her hull, or crew or equipment in normal
position, crosses the finishing line in the
direction of the course from the last mark,
either for the first time or after taking a
penalty under rule 44.2 or, after correcting an
error made at the finishing line, under rule 28.1.
8
Interested Party A person who may gain or lose as
a result of a protest committees decision, or
who has a close personal interest in the
decision. Keep Clear One boat keeps clear of
another if the other can sail her course with no
need to take avoiding action and, when the boats
are overlapped on the same tack, if the leeward
boat can change course in both directions without
immediately making contact with the windward
boat. Leeward and Windward A boats 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. Mark An object the sailing
instructions require a boat to leave on a
specified side, and a race committee boat
surrounded by navigable water from which the
starting or finishing line extends. An anchor
line or an object attached temporarily or
accidentally to a mark is not part of it.
9
Mark-Room Room for a boat to sail to the mark,
and then room to sail her proper course while at
the mark. However, mark-room does not
include room to tack unless the boat is
overlapped to windward and on the inside of the
boat required to give mark-room. Obstruction An
object that a boat could not pass without
changing course substantially, if she were
sailing directly towards it and one of her
hull lengths from it. An object that can be
safely passed on only one side and an area so
designated by the sailing instructions are also
obstructions. However, a boat racing is not an
obstruction to other boats unless they are
required to keep clear of her, give her room or
mark-room or, if rule 22 applies, avoid her. A
vessel under way, including a boat racing, is
never a continuing obstruction. Overlap See
Clear Astern and Clear Ahead Overlap. Party A
party to a hearing a protestor a protestee a
boat requesting redress a boat or a competitor
that may be penalized under rule 69.1 a
race committee or an organizing authority in a
hearing under rule 62.1(a).
10
Postpone A postponed race is delayed before its
scheduled start but may be started or abandoned
later. Proper Course A course a boat would sail
to finish as soon as possible in the absence of
the other boats referred to in the rule using the
term. A boat has no proper course before her
starting signal. Protest An allegation made
under rule 61.2 by a boat, a race committee or
a protest committee that a boat has broken a
rule. Racing A boat is racing from her
preparatory signal until she finishes and clears
the finishing line and marks or retires, or until
the race committee signals a general recall,
postponement or abandonment. Room The space a
boat needs in the existing conditions while
manoeuvring promptly in a seamanlike way.
11
Start A boat starts when, having been entirely on
the pre-start side of the starting line at or
after her starting signal, and having complied
with rule 30.1 if it applies, any part of her
hull, crew or equipment crosses the starting
line in the direction of the first mark. Tack,
Starboard or Port A boat is on the tack,
starboard or port, corresponding to her windward
side. Zone The area around a mark within a
distance of three hull lengths of the boat nearer
to it. A boat is in the zone when any part of her
hull is in the zone. Windward See Leeward and
Windward.

Bob Harvey
Luffing - When?, Where?, How Far?
15
Rule 17 On the same tack Proper
Course Definitions Tack A boat is on the tack
(starboard or port) corresponding to her windward
side. Proper Course A course a boat would sail
to finish as soon as possible in the absence of
the other boats referred to in the rule using the
term. A boat has no proper course before her
starting signal. (Note that this doesnt say in
the absence of other boats, just those mentioned
in a specific rule). Bobs definition of luffing
Sailing above close hauled up to dead into the
wind any further youd be tacking and Rule 13
would take over.
16
A boat may luff head to wind anytime during the
race when not forbidden from doing so by a
specific rule. She has the right to do so an is
only constrained by the requirement to give room
(not time) to keep clear Rule 16, and an onus
to avoid contact Rule 14. So, when cant a
boat luff? Rule 17 says If a boat clear astern
becomes overlapped within two of her hull lengths
to leeward of a boat on the same tack, she shall
not sail above her proper course while they
remain on the same tack and overlapped within
that distance, unless in doing so she sails
promptly astern of the other boat. This rule does
not apply if the overlap begins while the
windward boat is required by Rule 13 to keep
clear. Wow! .. Where the heck does that leave
us?
17
We know proper course can vary a bit from boat to
boat upwind, say as much as ten degrees, but
theres little doubt upwind that leeward boat,
while burdened by Rule 17, cant luff (sail above
close hauled) because that wouldnt be her proper
course. Downwind is a LOT more interesting!
Proper course varies all over the place for
different boat types in varying wind speeds
(Discuss!!). The leeward boat still cant sail
above her proper course while burdened by Rule
17, but that could be considerably higher than
the windward boat wants to sail. Lets remember
that Rule 17 only puts a burden on the leeward
boat, it does not convey a right to the windward
boat. Windward doesnt have any right to sail her
proper course! Leeward simply cant sail above
hers. Lets also remember that Rule 17 only
applies when the overlap is ESTABLISHED within
two of leewards hull lengths if the overlap
existed prior to the two hull length separation,
leeward isnt burdened by Rule 17 and can head as
high as they like.

You Make The Call

• You are rounding the weather mark and your keel
  snags the anchor rode and pulls the mark into
  your boat.
• There is a foul so you should re-round the
  mark.
• There is a foul so you should sail clear do one
  turn one gybe and continue the race.
• There was no foul because you hit the anchor
  rode, which is not part of the mark hence no
  foul.

You Make The Call

• You are finishing in light air and your bow
  crosses the finish line and are acknowledged by
  the race committee. Before you clear the finish
  line you touch the leeward mark.
• You ignore the touch because you have all ready
  been finished
• You circle around the mark , Gybe and then
  recross the Finish line
• You clear the line, do one gybe and one tack and
  recross the finish line from the direction of the
  last mark

You Make The Call

• In reviewing the posted score you find that the
  boat that finished behind you is scored ahead.
• Later in the bar, demand the race committee
  change the scoring.
• Storm out of the club vowing never to race again.
• Ask for a scoring review. Provide your finish
  time, and the number of the boat that finish
  ahead of you and the number of the boat that
  finished after you which you always record .
  Bring another competitor as a witness.
