"According to Appendix L of the Racing Rules of Sailing, if Flag D is displayed ashore but not all boats go afloat, how long must Flag D remain displayed before the warning signal can be made, and does this duration depend on what is specified in the Sailing Instructions?"
Flag D with one sound means ‘Boats [are requested not to][shall not] leave the [harbour][shore] until this signal is made. The warning signal will not be made before the scheduled time or less than <number> minutes after flag D is displayed.’
That SI does not state for how long flag D must remain displayed.
Seemingly the race committee may display Flag D with one sound signal then immediately removed the flag.
Alternatively, a protest committee considering redress for a boat that may have unavoidably been unable to hear the sound signal might conclude that the race committee was required to keep the flag displayed for a reasonable time.
Another good reason to use flag G to positively remain ashore while it is displayed.
I have used both Flag "D" and Flag "G" on many, many events.
Which I use depends on the legal responsibilities in the country I am running racing and the port/shore authority rules in the place where the racing is.
In many countries I have no legal responsibility for the safety of the sailors when they are not racing (and in some, even when they are racing!). In these countries I usually use Flag "G", removing it a good time before racing will start. I use it also when I am required to have boats inspected before launching to ensure they have the right kit aboard. I always get a PC member or Jury to follow the last boat out that launches within a reasonable time of the G flag being removed. Once that judge tells me they are on the race course I can go into sequence (as long as in accordance with the not before time in the SIs)
Where I am legally responsible for boats when they are not racing, I use Flag "D" when the support boats are in place and again I use a judge to make sure that all boats that launch within a reasonable time of the D flag being displayed have reached the starting area before I go into sequence. I remove the D Flag once there is no support boat lying off the launching area to ensure the safety of any boat that launches. The Beachmaster can raise it again if they think it is safe for a boat to launch. Often this boat will have a dedicated coach boat, Sometimes my safety officer vill have to send a boat to escort them out. It is then removed again.
The things we now have to do to guard ourselves against claims of negligence!
what does flag G mean? I ve never used and seen before, here in Italy we use only delta signal
Thank you
PS: or as an appendix "Appx ?: Auxiliary Race Signals"
"The following Race Signals are referenced in the Appendices and are only enforce when stated so in a race document governing the event" .. or something.
No, not appendices any more.
See Mark's response.

AIUI, a WS document identified as an Appendix, for example Appendix UF, is treated as an Appendix to the RRS and takes precedence over any conflicting rules in Parts 1 to 7 and the Definitions of the RRS (RRS Introduction, Appendices). So, if it is in an 'Appendix' it can change a RRS that NOR/SI otherwise can't change under RRS 86.1
In the 2021–2024 edition of the Racing Rules of Sailing, Appendices K and L, which contained the Notice of Race and Sailing Instructions guides, were removed. A note was added to the rulebook indicating where those guides could be accessed. In the 2025–2028 edition there is no mention of either appendix or their location.
It has been my observation that the RRC consider moving rules from the race documents (notice of race and sailing instructions) to the Racing Rules of Sailing when a high percentage of race documents issued by events in different countries contain the same NoR or SI rule.
A recent example would rule 62.2(a) in the 2021-2024 RRS. The Sailing Instruction Guide used to include a sailing instruction limiting the request for reopening time limit to 30 minutes, which most clubs included in their sailing instructions.
Sailing instructions that include the use of flag D by comparison are relatively limited.
That way it's only being shown/done when used.
I like the idea that racers can quickly see what these flags look like and mean by the race docs and RRS.
"6.3 [SP][DP] Flag D with one sound indicates Shore Launch. Boats shall not leave their assigned space until
this signal is made. The warning signal will not be made before the scheduled time or less than 60
minutes after flag D is displayed."
Flag G can be used with an appropriate SI such as:
When flag G is displayed boats shall not leave the shore.
This contrasts with the use of Flag D, meaning
When flag D is is displayed boats may leave the shore [and shall not leave the shore when flag D is not displayed).
If they want to use flag G, the race committee might have to get up early in the morning to display it, or else the race committe might choose not to concern itself with a boat that wants to go out for an early training session.
I have only seen the D flag used at larger Opti events. It is my understanding that it is serving a dual purpose, the class wants to have some limit on the kid's overall time on the water and the organizers want to know when people are going out to help them keep track for safety reasons.
