Obstruction - Start / Finish Line
 
Our club prohibits crossing the start / finish line except to start or
finish. The entire area, including nearby extensions of the start /
finish line, are navigable. Our sailing instructions do not modify
RRS 28.1 (the "string" rule) in this regard, so "unwinding" is
permitted.

A handful of sailors had a lively discussion over beer one night
regarding whether the prohibited start / finish line ranks as an
obstruction. It is clearly not a mark - boats can (and do) leave this
area to either side depending on individual polars or tactical
circumstances.

The RRS definitions state that an obstruction is "an object that a
boat could not pass...", but the line is not an object. Further, the
definitions state that "...an area so designated by the sailing
instructions (is) also (an) obstruction...".

Does the prohibition of crossing the line in the sailing instructions
make the "area so designated by the sailing instructions" an
obstruction, or would the SIs have to specifically state that the line
ranks as an obstruction?

Obstruction - Start / Finish Line
 
Hi Jim,

There are several different issues in this topic.

The string rule is irrelevant. The start/finish line marks do not begin
or end the leg in question, and they do not have a required side.
Therefore they are not "marks" according to the definition. The string
rule does not prohibit multiple roundings of a required mark, and it
says nothing at all about objects that are not marks.

The prohibited area is clearly an "obstruction" if the prohibition is
properly written into the sailing instructions. Typically this sort of
sailing instruction would be used to prevent potentially dangerous
shortcuts, avoiding commercial traffic, and so on. If written carefully,
with particular attention to the definition of the exact prohibited area
and the time in which the prohibition is in effect, it should be
possible to use this approach.

The prohibited start/finish line, or closed gate as it is sometimes
called, is full of problems. It potentially makes life easier for the
RC, but it creates strategic headaches for the competitors. It is not
allowable for the RC to simply toss a violator unless the rules are
modified. Rule A5 requires a protest hearing to "worsen a boat's score"
for all but a couple of specific reasons. The rule modification is
possible, but it requires adjustments to at least rules A5, A4.1, 63.1,
and 28.1.

It does not make a lot of sense to have a prohibited area that can be
violated and then "un-violated" as you seem to indicate. If the area is
prohibited for good reason, then protest and toss the perps. If the
transgression can somehow be undone by unwinding the course, then it
would not appear that the prohibited area made much sense in the first
place. The rules are generally unforgiving with regard to "innocent
mistakes".

Been there, done that, got burned, learned, etc.

If it is desired to treat the line as an obstruction, that is, creating
an entitlement to room under RRS 18, then the SI should explicitly
designate the thing as an obstruction.

But by designating start/finish lines as obstructions, you are
destroying the principles that allow one boat to force another over at
the start.

The effect of your local SI is a rather ham-fisted attempt to do what
the Flag I, Flag Z and Black Flag starting options in RRS 30 provide in
a carefully thought out way (with effective penalties, that won't
require a protest hearing). Why not use the carefully developed rules
provided?

The RRS don't provide a specific rule to keep the finish line clear, but
if this is really a problem, bearing in mind that the SI probhibition
will require a protest hearing to deal with an infringer, then it can
probably be dealt with better by:

* _requesting_ boats not to cross or re-cross the finish line except
when finishing (in the SI, or general notices), (this works fine with
several clubs where I race) and

* locating the finish line sufficiently away from nearby rounding marks
so that boats that are racing do not come near it, for example, 200 m to
windward of the windward mark of the course, or to leeward of the
leeward mark, if a downwind finish.

Thanks, Gene and John. Our ham-fisted attempt wasn't to recreate the
RRS 30 system, it was to keep boats out of the finishing area on laps
of the course between starting and finishing. We have boats of widely
differing speeds sailing different courses, and could end up with a
boat under spinnaker hauling butt to finish, only to have to deal with
a slower close hauled boat going back to the weather mark. The intent
is to keep the slower boat out of the finish line for safety purposes.

The reason that we allow someone to correct an error of going through
the line is that the Southern Chesapeake Bay gets some crazy currents
at times, and is possible for a boat to drift across the line without
the helmsman being able to prevent it. Under those drifting
conditions we are less concerned about the posibility of collision.

We are constrained by the shape and size of our Willoughby Bay and
cannot offset the starting line. I'm also not an favor of
"requesting" that competitors do something - there needs to be a
consequence.

It is not a problem that the RC would have to protest a competitor for
violating the line. It doesn't happen often enough for that to be an
issue.

The main question is whether the SIs have to use the word
"obstruction" in defining the area to be avoided, or is the fact that
it is a prohibited area enough to make it an obstruction for the
purposes of Rules 18 and 19?

Gene - Best of luck with the Lakefest Regatta next weekend. I wish I

Hi Jim,

I understand exactly what you are trying to do, because we tried the
same thing for many years in both TSC club racing and in open events
such as Lakefest.

As you know, we get some really high level officials on board for
Lakefest, with national and international race officers and judges. To a
person they told us the closed start/finish line was unworkable. The RRS
do not really accommodate this closure, and anyone appealing a DSQ would
probably win.

If your club is willing to go along with a valiant attempt to modify the
rules it may work, but perhaps not if you have genuine sea lawyers
involved. I agree that a "request" is not a good idea.

We gave it up for Lakefest to avoid the pitfalls. To maintain sanity of
the RC we have changed all the courses to remove the need for a closed
line. Any boat crossing the line other than starting or finishing is way
off course, so the number of incidents is very small.

As to your question of wording the SI's, the definition seems pretty
clear. An "area so designated by the sailing instructions [is] also an
obstruction". There is no mention of why the area might be selected,
such as being a prohibited area. There is no automatic designation other
than one that is safety related. It is not allowed to change the RRS
definitions. Therefore the SI's must explicitly designate the area as an
obstruction.

A closed line only makes sense where the line lies between the
windward and leeward marks. To avoid the problem entirely, just ensure
that leeward mark is either upwind of the line, level with the line,
or uses the non-RC end as the leeward mark. However, it is easier to
separate boats by just dropping a finish mark a short distance to
starboard (usually) of the RC boat. If any line needs to be 'closed'
it can be that one, unless your conditions are such that you may still
be starting boats while prior starters may be transiting the area
(presuming you still have the leeward mark to leeward of the line).

If all this fails or cannot be done, there is one method which will
beat the sea-lawyers:

You must define each non-starting/finishing leg as requiring that BOTH
of the RC and the Start mark must be left, (at the helmsman's option)
either to port or to starboard.
'... from mark 3 to mark 4 leaving both of mark 1 and the Race
Committee vessel to starboard, or both of mark 1 and the Race
Committee vessel to port...'

This allows 'un-stringing' in case of error and protest ("did not
string") in case of failure.

In the Toronto area we gave up on this sort of idiocy about 20 years
ago....It is MUCH simpler to restructure things to completely obviate
any need for.

This is good advice, but assumes it's possible. Some fleets race in
constricted waters where geography (hydrography?) force you to set
courses that you might otherwise prefer not to, especially when using
fixed marks.

I've become a big fan of the setup R.G. suggests, when it's possible.
We set a start/finish line square to the wind and a windward mark dead
upwind. Then, we drop the leeward mark about 100 yards to windward of
the RC boat, and have a downwind finish. This gives you a couple of
advantages:

1) If the wind shifts, you only have to move one mark (the windward
one). Unless the shift is really radical, the leeward mark can stay
where it is, and it's not critical that it gets set exactly. The chase
boat can just toss it over the side on the way up to set the windward
mark and forget about it. This really helps out when the RC is
shorthanded and you've only got a single chase boat.

2) The spinnaker drops all happen right in front of the RC boat. This
not only adds to the RC's entertainment factor, but makes for great
photography as well.

If you are writing the sailing instructions and you want it to be
treated as an obstruction, then be sure to use the word "obstruction"
in your declaration as well as "prohibited". That way the SIs will
communicate clearly to the racers that it is to be treated as an

Hi Geoff,

This is probably beating a dead horse, but here goes.

Your anti-sea-lawyer solution won't work. The definition of "mark" says,
"An object the sailing instructions require a boat to leave on a
specified side . . . ." There is no option to allow a "mark" to have
anything but ONE specified side. Changing definitions is not allowed.
Rule 28.1 could be changed to modify "sailing the course", but it would
need to avoid the use of "mark". Sounds like a real mess.

Mid-course start/finish lines can be useful in several situations.
However, it is necessary to either leave the line "open" or jump through
a bunch of hoops in the SI's to try to "close" the line.

Gene Fuller

Could you elaborate in general terms why the international jurists have
said this is so?

What would be the problem with the following SI based on RRS 29.1

"If, other than when a boat is _finishing_, any part of a boat's hull,
crew or equipment is on the side of the finish line farthest from the
last mark, the boat shall sail completely to the side of the finish line
nearest the last mark before _finishing_. This modifies RRS 28.1"

This could be elaborated along the lines of RRs 30.2/3 to provide for a
percentage penalty or a DSQ (and also allow it to be "switched on/off"
by a flag signal depending on the conditions).


If your club is willing to go along with a valiant attempt to modify
the rules it may work, but perhaps not if you have genuine sea lawyers
involved. I agree that a "request" is not a good idea.


OK, the "request" situation works to keep already-finished boats clear
of the finish line. If the prospect of a "little chat' with a flag
officer about sportsmanship and co-operating with the RC isn't enough to
induce people to co-operate, then I'm sorry for you. Obviously,
district regattas are a little different.

We gave it up for Lakefest to avoid the pitfalls. To maintain sanity
of the RC we have changed all the courses to remove the need for a
closed line. Any boat crossing the line other than starting or
finishing is way off course, so the number of incidents is very small.


If you can't get longitudinal offsets as illustrated in RRS Appendix K
Addendum A, then maybe you could try a lateral offset as shown in the
Match Racing SI 10.1 at

http://www.sailing.org/matchrace/mrssi.doc

Maybe this is what RG is suggesting.

As to your question of wording the SI's, the definition seems pretty
clear. An "area so designated by the sailing instructions [is] also an
obstruction". There is no mention of why the area might be selected,
such as being a prohibited area. There is no automatic designation

area as an obstruction.


But I think the discussion in this thread indicates that you don't want
to make the line an obstruction, and confer rights to room.

Sorry, on offence intended.

Well, boats meet in this situation all the time on the race course away
from the finish line: why is it any different? You've got the whole of
RRS Pt 2 to take care of it. It might be different if your finish line
was in some narrow channel, not surrounded by navigable water.

It is not a problem that the RC would have to protest a competitor

See my comment above: by making the SI an amendment to RRS 28, you can
provide for exhoneration, percentage or DSQ without a hearing.

The main question is whether the SIs have to use the word
"obstruction" in defining the area to be avoided, or is the fact that
it is a prohibited area enough to make it an obstruction for the

I think we've all said that, if you want it to be an obstruction, the SI

Ryk

There are a few other problems associated with a SI that indicates the
Finish Line is a 'prohibited area' unless finishing.

(1) Light air starts, class just gets across the line, air shuts down,
current pushes them back through the start-finish line. Now what?

(2) Most of the SI's identify the situation as 'prohibited' or wording to
that effect but do not spell out a consequence of going through the finish
line before a finish. So, off to the Protest Committee, and the Committee
says fine, but what is the penalty -- none spelled out in the SI's.

(3) Due to rough weather, the RC Boat gets moved around and in effect so
does one end of the Finish Line. Along come boats on a leg, trying to
figure out where one end of the Finish Line is so as to stay clear, but the
RC boat is all over the place, perhaps the line 'grew' substantially from
when the classes were started, and boats searching for the outer pin,
unknowingly cross through this new finish line. It happens. Happened to us
two seasons ago, we were in the lead, and we retired once we figured out
where the heck the other end of the line was (behind us and maybe a few
hundred yards further out and back in relationship to the RC boat). Yes, we
could have continued and appealed, but at the time we did not know the RC
boat was pulled off its position. And since the Start-Finish line is at
times in the middle of some legs, you either take it on the pin or on the RC
boat sides.

Well, it will always have to be a 'mark' because the we are requiring
it to be left on a specified side.. And my formulation does not change
the definition, only the manner in which the specified side is
determined. And that is quite clear.
There is nothing in the rules which requires that a mark have only one
'side' *under all circumstances*. The instructions can require that a
mark may have a differing required side under differing circumstances.
In this case, the required side is that side chosen by the helmsman
which leaves both marks on the same side. In effect, the helmsman
specifies the side, for both marks.

Your interpretation would make it impossible to allow yachts to round
any group of marks in either direction, and would make it impossible
to stage a race from a start to and around an island, *in either
direction* as in one direction the island would be left to port, and
in the other, to starboard.


Mid-course start/finish lines can be useful in several situations.
However, it is necessary to either leave the line "open" or jump through
a bunch of hoops in the SI's to try to "close" the line.


I have never been able to figure out any of those 'useful' situations.
Even with fixed mark courses, it is simpler to set the line at the
leeward end of things, or just start at one point and finish
elsewhere. Most excuses for using the mid course setup amount to a
lack of RC capabilities (boats, marks etc) which are reasonably
avoidable or surmountable. If they can set up in the middle they can
do so at the bottom. If there is no working space at the bottom, then
start at the middle, but do not attempt to finish there! Then there
is no start line after the start and therefor no problem.

But closed midcourse start/finishes are just a problem waiting to
happen and should not be used. Anyway, mid-course lines rarely easily
handle any sort of wind shift leading to lousy racing... And RC's do
not set out with the intention of providing lousy races... well at

"Obstruction... an area so designated by the sailing instructions...."
RRS Definitions.


If you are writing the sailing instructions and you want it to be
treated as an obstruction, then be sure to use the word "obstruction"
in your declaration as well as "prohibited". That way the SIs will
communicate clearly to the racers that it is to be treated as an
obstruction. It may or may not be a legal requirement, but it never
hurts to be explicit.


The word 'prohibited' is not strictly actually necessary as it is
essence of being an obstruction that requires it to be sailed around
(rather than through)... But there is no doubt that adding this word
makes the meaning clearer.
Of course, making it clear only applies to that subset of the racers
who read the instructions, and among those, to the subset who actually
understand the instructions....So 24 point bold type might be in
order!

There are a few other problems associated with a SI that indicates the
Finish Line is a 'prohibited area' unless finishing.

(1) Light air starts, class just gets across the line, air shuts down,
current pushes them back through the start-finish line. Now what?


If your SI's are screwed up then this is a problem. If the SI's say
'Except when starting or finishing, the line is ...(prohibited)' then
you deserve every problem which arises....
If your SI's say 'When proceeding from mark 1 to 3 or mark 3 to 4, ...
the line is (prohibited)' then you have no problem as your recent
starters are not yet on a leg when crossing the line is prohibited.

In part, this is why I would and did nominate the line ends as marks
of the leg when prohibiting passage between them. Under the old rules,
marks only had 'sides' when on a leg which that mark began, ended or
bounded. And more racers understand room at a mark than understand
room at an obstruction...

(2) Most of the SI's identify the situation as 'prohibited' or wording to
that effect but do not spell out a consequence of going through the finish
line before a finish. So, off to the Protest Committee, and the Committee
says fine, but what is the penalty -- none spelled out in the SI's.


Denominating them as marks provides a penalty through 'sailing the
course'..

(3) Due to rough weather, the RC Boat gets moved around and in effect so
does one end of the Finish Line. Along come boats on a leg, trying to
figure out where one end of the Finish Line is so as to stay clear, but the
RC boat is all over the place, perhaps the line 'grew' substantially from
when the classes were started, and boats searching for the outer pin,
unknowingly cross through this new finish line. It happens. Happened to us
two seasons ago, we were in the lead, and we retired once we figured out
where the heck the other end of the line was (behind us and maybe a few
hundred yards further out and back in relationship to the RC boat). Yes, we
could have continued and appealed, but at the time we did not know the RC
boat was pulled off its position. And since the Start-Finish line is at
times in the middle of some legs, you either take it on the pin or on the RC
boat sides.


This is the major stupidity involved in having the RC in the middle of
the arena.

Bad setup, bad result.

Realistically, if you figure you absolutely must have the RC in the
middle, exactly WHY is it so important that the line be closed?
Except for the RC's convenience? If it is because the RC likes it that
way, they are not doing their proper job.

And if the Finish line has the RC boat and outer pin designated as marks,
and a boat passes through that 'invisible line, it probably then can correct
itself, by coming back and going around either end and sailing a proper
course.

One must understand that not all race courses are windward-leeward, and you
probably do. Modified Olympic courses have the RC boat in the middle, and
various marks of equal distance radiating out from it. In this case, there
are 8 rounding marks, all .75 miles from the RC boat, each mark 45 degrees
on angle. So a variety of possible legs, some .75 miles, some 1.5 miles.
Other courses of a similar makeup have 6 marks. And so on. But the RC boat
is central, and some of the legs, besides start and finish, bring boats on a
line by the start-finish area.

In terms of why a line msut be closed probably had more to do with various
classes out on the course, slow classes going first. Hence, closing the
line to just finishes not only helps the RC in recording finishes, but
avoids any confusion/mayhem that might occur when you have: boats finishing
but are mixed in with boats still sailing a non-finishing leg (certain rules
apply to a finishing boat that do not apply to another); and another class
coming from the opposite direction through the finish line while still on a
longer racing leg, opposed to boats trying to finish. It does happen.

Even some windward-leeward courses have the RC boat on the course, closer to
the leeward marks/gates.

But, regardless of how the start-finish restriction may be stated in the
SI's, unless there is linkage to a definition of penalties, or ways an
offending boat can correct itself without penalty, the rule is useless when
it comes to a Protest Committee hearing. Nothing is 'understood'.


Now with starting boxes, as an example, regattas spell that out very
clearly. If you are in your start, you stay in the box or this may happen.
If it is not your start and you offend, then this may happen.

Could you elaborate in general terms why the international jurists have
said this is so?


Note that I used the word "unworkable", not illegal, immoral, etc. The
Changes to the SI's are not trivial, as demonstrated in this newsgroup
thread. Getting it right in all conceivable circumstances is not easy. I
cannot find any appeal is the ISAF case book that deals with this
subject, but I will guess that most SI's that attempt to deal with issue
would come up short.



What would be the problem with the following SI based on RRS 29.1

"If, other than when a boat is _finishing_, any part of a boat's hull,
crew or equipment is on the side of the finish line farthest from the
last mark, the boat shall sail completely to the side of the finish line
nearest the last mark before _finishing_. This modifies RRS 28.1"


I don't think this will work. In many cases, perhaps most cases, the
entire reason for attempting to close the line is to avoid confusion
during a multilap race. In such circumstances your proposed rule would
be violated constantly. Boats have a perfectly legitimate reason to be
on the wrong side of the finishing line in the middle of the race.
Again, this does not demonstrate that it is impossible to set up such a
limitation, but it is not at all trivial.

This could be elaborated along the lines of RRs 30.2/3 to provide for a
percentage penalty or a DSQ (and also allow it to be "switched on/off"
by a flag signal depending on the conditions).


If your club is willing to go along with a valiant attempt to modify
the rules it may work, but perhaps not if you have genuine sea lawyers
involved. I agree that a "request" is not a good idea.



OK, the "request" situation works to keep already-finished boats clear
of the finish line. If the prospect of a "little chat' with a flag
officer about sportsmanship and co-operating with the RC isn't enough to
induce people to co-operate, then I'm sorry for you. Obviously,
district regattas are a little different.


Most sailors believe in sportsmanship, and some even practice it. The
"request" is fine until someone disagrees. I have no issue with informal
agreements and requests, but what happens if there is a violation,
intentional or not? Does the RC ignore it? Other sailors might ask for
redress. Can another boat lodge the protest? Probably, unless the SI's
deal with that possibility. What is the penalty? Does a 720-rule apply?


We gave it up for Lakefest to avoid the pitfalls. To maintain sanity
of the RC we have changed all the courses to remove the need for a
closed line. Any boat crossing the line other than starting or
finishing is way off course, so the number of incidents is very small.



If you can't get longitudinal offsets as illustrated in RRS Appendix K
Addendum A, then maybe you could try a lateral offset as shown in the
Match Racing SI 10.1 at

http://www.sailing.org/matchrace/mrssi.doc

Maybe this is what RG is suggesting.


As to your question of wording the SI's, the definition seems pretty
clear. An "area so designated by the sailing instructions [is] also an
obstruction". There is no mention of why the area might be selected,
such as being a prohibited area. There is no automatic designation
other than one that is safety related. It is not allowed to change
the RRS definitions. Therefore the SI's must explicitly designate the
area as an obstruction.



But I think the discussion in this thread indicates that you don't want
to make the line an obstruction, and confer rights to room.


The obstruction issue is very easily handled, and I do not have the
slightest problem with making the line an obstruction. However, one must
figure out how to close the line in the first place.

Obstruction - Start / Finish Line
 
Thanks for the input, everyone. Just for those who are interested, we
use a mid-course start / finish line for our Thursday night beer can
races. We use two drop marks (in addition to the start and finish
marks) that are always in the same position, and a government channel
marker. Sometimes we get windward legs, sometimes the entire race
consists of reaches. All boats sail three legs, and the spinnaker
boats additionally sail to the "weather" mark and back to the finish.
This results in boats finishing from both directions simultaneously.
We therefore have separate finish lines for the two fleets, with the
committee boat in the middle.

The most interesting thing about our racing is the Navy operations
that often occur in the area. We often get Seals jumping out of
helicopters into our race area, and then they get retrieved. We also
get an occasional antisubmarine sled towed through the course. Not
great for "real" racing because of the requirement for us to stay well
clear of these operations, but good enough for this level of
competition.

We normally have about 20 nonspinnaker boats and 10 spinnaker boats
registered. Most are learning to race or trying to improve racing
skills for the more important weekend races with other clubs.

Thanks again,

Jim Williams

Other courses of a similar makeup have 6 marks. And so on. But the RC boat
is central, and some of the legs, besides start and finish, bring boats on a
line by the start-finish area.


This was the form of course used for quite a number of years in the
Toronto area and still is by some of the local clubs.
Having the RC in the middle was 'easy' but not always 'good'.
The last year or 2 that this setup was used, the line was proscribed
by using the wording I set out " when proceeding from mark 2 to 3,
mark 1 and the RC shall be left either both to starboard, or both to
port". They may or may not have also said, the line between the RC and
mark 1 is an obstruction to any boat sailing a leg which does not
commence or end at the start or finish line.

But having the RC in the middle always gave lousy racing for
closewinded boats when the wind shifted. Having the RC at the bottom
was not much better. There were some trials which made the line a gate
on the second round, so that a change of course could be made,
providing a better beat for 1/2 of the round (in contradistinction to
a fetch from the 'bottom'). In the end, we stopped using fixed mark
courses. Locally Ashbridges Bay YC continues to use a fixed circle of
marks for weeknight racing, but starts are from the bottom and course
changes are rare if not extinct. Still gives good weeknight racing:
its not the full-on level, its the full-fun level!
The RC uses the 'bottom' mark as the start/finish pin, and even if
fleets are still starting when the first (fast) boats get back, the
problem is for the incoming boats (on port and rounding into the face
of the starboard starters!)..

In terms of why a line msut be closed probably had more to do with various
classes out on the course, slow classes going first. Hence, closing the
line to just finishes not only helps the RC in recording finishes, but
avoids any confusion/mayhem that might occur when you have: boats finishing
but are mixed in with boats still sailing a non-finishing leg (certain rules
apply to a finishing boat that do not apply to another); and another class
coming from the opposite direction through the finish line while still on a
longer racing leg, opposed to boats trying to finish. It does happen.


Personally, I now believe that any course which seems to 'require' a
closed line, is a cop-out by the RC. There is no real reason why the
RC *has to* remain exactly *there* to finish the racers. It *may* be
reasonable to start from there, but realistically the RC could just as
easily move to some other point of the course to finish boats. It does
not have to anchor.

Even some windward-leeward courses have the RC boat on the course, closer to
the leeward marks/gates.


But the line should NOT be immediately to weather of the leeward mark
*AND* closed. The RC should be below the leeward mark. If the RC wants
to use the leeward mark as the pin it should move to the other side so
that all boats leave the pin to port.

But, regardless of how the start-finish restriction may be stated in the
SI's, unless there is linkage to a definition of penalties, or ways an
offending boat can correct itself without penalty, the rule is useless when

If you feel you *have to*, then making them marks, and defining the
course to proscribe passing between them automagically provides the
penalty....DNF for not sailing the course!

There were USYRU and IYRU cases about 'required sides' etc. and the
'string rule' which discussed this... Long since lost in the mists of
history unfortunately.

Geoff,

The current definition of "finish" does not require "sailing the

The only option allowed to a Race Committee if a boat does not sail the
course correctly is to protest the infringing boat. Automagical DNF
penalties are not allowed. If a boat crosses the finish line from the
direction of the last mark it has finished, subject only to the
technicalities spelled out in the definition. Note that the boat does
not need to round the last mark; it only needs to cross the finish line
from the direction of the last mark.

I won't argue whether this is right or wrong, but it is the current
rule. See ISAF Case 45 for further reinforcement that the definition of
finish cannot be changed.

What you seem to be getting at is that, while it may be difficult but
not impossible to draft a binding SI, 'closing' a finish line that is
'inside' the course, is a poor solution to the problem of potential
confusion for the RC.

I'm inclined to agree with you for the following reasons:

* for high level (district/province/national) racing having an
artificial closed line in the middle of the racecourse is obviously
detrimental;

* for club racing, surely there aren't so many boats our there that the
RC can't keep track of them, if they keep their mind on the business
(and delegate etc).

BUT, for club-level racing, I think we've got to recognise that the
hard-working Race officers, who may not be all that numerous to permit
delegation, should be cut a bit of slack to try to balance up making
their own lives a little easier, while not too much creating bad race
courses.


What would be the problem with the following SI based on RRS 29.1

"If, other than when a boat is _finishing_, any part of a boat's
hull, crew or equipment is on the side of the finish line farthest
from the last mark, the boat shall sail completely to the side of
the finish line nearest the last mark before _finishing_. This
modifies RRS 28.1"


I don't think this will work.


I have to agree with you. As drafted it 'catches' boats crossing the
extensions of the finish line, every time they go past. I guess I was
trying to be a bit too clever.

If Jim or anyone else wants an improved version, I'll try again, if
asked.

In many cases, perhaps most cases, the
entire reason for attempting to close the line is to avoid confusion
during a multilap race.


I note that Jim (OP) said that the primary reason was safety, to
separate fast-moving, free sailing finishers from slow beating boats,
which I didn't think was a very good reason, for a finish line
surrounded by navigable water.

In such circumstances your proposed rule would
be violated constantly. Boats have a perfectly legitimate reason to be
on the wrong side of the finishing line in the middle of the race.
Again, this does not demonstrate that it is impossible to set up such
a limitation, but it is not at all trivial.

This could be elaborated along the lines of RRs 30.2/3 to provide
for a percentage penalty or a DSQ (and also allow it to be "switched

If your club is willing to go along with a valiant attempt to modify
the rules it may work, but perhaps not if you have genuine sea
lawyers involved. I agree that a "request" is not a good idea.


OK, the "request" situation works to keep already-finished boats
clear of the finish line. If the prospect of a "little chat' with a
flag officer about sportsmanship and co-operating with the RC isn't
enough to induce people to co-operate, then I'm sorry for you.
Obviously, district regattas are a little different.


Most sailors believe in sportsmanship, and some even practice it. The
"request" is fine until someone disagrees. I have no issue with
informal agreements and requests, but what happens if there is a
violation, intentional or not? Does the RC ignore it?


RC, if it wishes discusses it with the flag officers who act as they
think necessary.

RC could act under RRS 2/69.1, but if RRS 2/69.1 were to be invoked,
then I would expect it to apply regardless of whether there was a
'request' on the books or not.

Other sailors might ask for redress.


Not unless one of the four circumstances in RRS 62.1 apply, most
probably breach of RRS2/69.1.

Can another boat lodge the protest? Probably,


Yup, any boat can protest about anything: RRS 60.1, but, apart from RRS
69.1, the only way a protest can have an outcome is when a _rule_ is
broken. A "Request" is not a rule.

unless the SI's deal with that possibility.


And the SI would be really standing into danger if they attempted to
apply some 'automagical' penalty for breach of a non-rule Request.

What is the penalty? Does
a 720-rule apply?


720 penalties only generally apply for breaking RRS Part 2 When boats
meet.

If you wanted to impose a 'turns' or a percentage penalty for breach of
other than a When boats meet rule inserted in the SI:

* firstly, as you have prevously observed, you have to get around RRS
63.1, at least by referencing and modifying RRS 63.1; and

* secondly exactly describing how the penalty shall operate, for
example as is done in RRS 32.1.

But, as I have agreed with you above, you can't expect seriously
competitive sailors to suffer an artificial 'closed' line in the middle
of their race-course gladly.

Geoff,

MMMMMM, I understand:

If the finish line is in the middle of the race course, a boat can
"finish" numerous times as she passes through the finish line from the
direction of the last mark, on various legs or laps.

But a boat can only sail the course under RRS 28.1 once.

I think this is a somewhat tortured construction, and I think it would
be correct to imply into the definitition of _finish_ words to the
effect of "after properly rounding the last mark".

Otherwise, or as well, there should be implied or expressly written into
RRS A4.2, immediately before the word _finish_, the words "sail the
course in accordance with rule 28.1 and".

The only option allowed to a Race Committee if a boat does not sail
the course correctly is to protest the infringing boat. Automagical
DNF penalties are not allowed.


Do you have an Appeals Case for this. I don't think Case 45 gets quite
there.

If a boat crosses the finish line from
the direction of the last mark it has finished, subject only to the
technicalities spelled out in the definition. Note that the boat does
not need to round the last mark; it only needs to cross the finish
line from the direction of the last mark.


I disagree: although a 'black-letter' construction of the definition of
"finish" indicates this, such an interpretation leads to the absurdity I
described above, that a boat can "finish" numerous times in the same
race. The canons of construction allow for interpretation or
implication to remove absurdities. As I indicated, it think it is quite
proper and right to imply "after properly rounding the last mark" into
the definition of _finish_.

I won't argue whether this is right or wrong, but it is the current
rule. See ISAF Case 45 for further reinforcement that the definition
of finish cannot be changed.

Sorry if I was unclear. There is a penalty available if a boat does
not sail the course. That penalty can only be applied on protest.
The point is that there is a penalty structure if the closed line is
bounded by marks. That is not so clear if it is an obstruction.

Unfortunately, as I have pointed out here before, many useful concepts
were tossed out when the rules were screwed up.

The definition of 'finish' requires that finishing be 'from the last
mark'. The last mark must be 'touched' by the string. Note that if the
line is closed by making the ends marks, those marks are NOT rounding
marks, and the string need not touch them. In fact, it would touch one
of them but not the other, if both are to be left on the same side.

As to multiple 'finishes': that does not happen, since it is only a
finish when it happens '...from the last mark...'

The others are just...laps?

I think you're misquoting the defintion of _finish_.

The definition I have says "... crosses the finishing line *in the
direction of the course from the last mark* ..."

The last mark must be 'touched' by the string. Note that if the
line is closed by making the ends marks, those marks are NOT rounding
marks, and the string need not touch them. In fact, it would touch one
of them but not the other, if both are to be left on the same side.

I disagree that that is what the definition says. Without further
interpretation it says

"A boat finishes when any part of her ... crosses the finishing line in
the direction of the course from the last mark ... "

Taken literally, this means that every time a boat crosses the finishing
line in the direction of the course from the last mark, the boat
"finishes".

As I've previously said, I think this is a somewhat tortured
construction, and is clearly unnecessary. It can be cured by making the
necessary implication, as you have done.

The others are just...laps?

It is not a 'necessary implication' although you seem to think it
necessary. Yours is definitely tortured: as you interpret it, a boat
would 'finish' after the first half round of a multi-lap race, merely
by sailing between the RC and the mark which is denoted as the other
end of the finishing line. That is not the intention of the race, nor
of the rules.
Moreover, that interpretation would REQUIRE that every boat sail
through the 'finishing line' on every lap because the finishing marks
would therefore have a required side *at all times*.

The thing which we simply call the 'finish line' does not become an
actual 'finishing line' until a yacht has rounded the penultimate
mark and commenced the last leg. Prior to that point, the ends of the
'finishing line' are marks of the course, but have no required side.
See rule 28.2.

The discussion has been about whether to/how to give those marks a
required side at an earlier point in time in the race.

The bit about 'in the direction of the course from the last mark' is
meant to take care of lousy RC's who set weird lines which would
require a button-hook finish. And 'last mark' is not just 'the
immediately preceding mark' but 'the penultimate mark of the course'.

You ought also to give some thought to the fact that in the example we
have been dealing with, the line is also the starting line....??still
and forever???

Get out your rule book and read it through about 5 times. Then browse
to the ISAF site and look at some of the rules examples and cases.
