Living on an island, off an island, I have cause to travel on ferries from time to time.
On passenger ferries they give a safety brief over the PA, like on planes. This safety announcement states that if you hear seven or more short blasts on the ship's whistle and general alarm, followed by one long blast, you should proceed to the muster stations.
Now this has always puzzled me. Why it is it seven or more? Why not exactly seven or any other specific number? I have asked a Stena Line Captain who drives one of the ferries on the Belfast Cairnryan route and he doesn't know and google, wiki, etc don't give a specific answer. I even had the question asked on the "homework sucks" feature on Simon Mayo's Drivetime programme on Radio 2 but just got the standard wiki answer which doesn't really answer the question.
I assume, as with most nautical things, there is some tradition, probably navy, for this but I would really like to know the answer as it something that has bugged me for years.
So come on Differs, put my mind to rest with the correct answer.

Probably because 7 or more short blasts can not be mistaken for any other signal - it's a wake up call to get you moving...

In some places the abandon ship alarm is 6, in most places it is 7.
My guess is thus:
The international maritime standard for sound communication includes sounds up to 5 short blasts (passing port, passing starboard, rear propulsion etc), therefore the general alarm has to be more than this. 6 is of course more, but in the heat of the moment may possibly be miss-interpreted, thus 7 is the norm.

If you hear the tannoy called for the "Carpenter to go to the bridge", then that is the time to worry and put on a life jacket.
The carpenter has the historic job of keeping the wet stuff on the outside and is in charge of the bilge pump. So an urgent call means he has to report how bad it is downstairs.

From what I remember from my BOT ticket...
1 short = I am turning to starboard
2 short = I am turning to port
3 short = I am going astern
5 short = What is your intention (or What the hell do you think you are doing)
7 short = I am no longer on this sinking ship so if I were you I'd join me...

Ships do not have carpenters any more and it is the engineers who do the bilge pumping at the behest of the chief officer.

Why ruin a good story with the facts?

I love it when they make you do the drill as your setting off, you get all the old dears with the huge life vest on trying to get down the corridors and through the wee doors.

So that explains why the Titanic sank! The engineer ran out of duck tape.

It's so you can gauge how fast your sinking. If the water is muffled by the third beep your going down fast but if it's the sixth beep there's not such a panic.

Why 7 short blasts?
As said above the 1, 2 & 3 have disticnt meanings
Quote: | 1 short = I am turning to starboard
2 short = I am turning to port
3 short = I am going astern - engaging astern propulsion (quite different as ships also use 'reverse thrust' to slow down) |
5 is more than 1, 2 or 3 so if you hear 4 or more you know there is something wrong. There is no '4' as you can't be sure that you didn't miss the first one and confuse it with 3 as if you hear 4 then it can;t be three and therefore must be 5. Also its less than 7 so you can't confuse it with the panic stations below.
As to 7 blasts - its in reality it will be 7 or more - it doesn't matter how many coz you're doomed as it really gets your attention that there is major stuff happening! Same reason as to why no 6 as above - to prevent accidental confusion with any other signal coz this is the big one.
Ships(RN) do have carpenters - its the Chippy. A sub spec of of the Marine Engineering Branch. Does everything from woodwork to specialist bits of metal fabrication. Yes we do woodwork because the best leak stopping/hole filling supports are wooden beams. Strong, resilient and easily cuttable. General repair techniques and stuff like that.
However the Chippy should not be confused with Q. Nor should James Bond or the Borg get any ideas! Q is short (in old speak) for NBCDQ - the Nuclear, Biological, Chemical and Damage Repair Qualified person - the head trainer in the self protection measures for what I just typed above off the top of my head without checking.
Sorry - what was the question again.

Not fair - I liked the Carpenters. Karen wasn't that bad
(Oh, by the way its a Main Broadcast - Butlins and Railway Stations have tannoys! Also - the use of language is a give away too:
"The Carpenter is requested to go to the Bridge" - all nice and calm no probs and you can relax.
"Carpenter, Bridge" - the Captain is grumpy about about something. Be careful.
"Carpenter, Bridge at the rush" - major probs - most likely that Captain Schettino's bed has collapsed under the weight of Moldavian Dancing girls and needs repairing)

I used to think that Karen was good too - have you seen the videos of her lately - you might change your mind
Regarding Tannoy - I have an authentic Tannoy speaker in battleship grey, complete with volume knob, (in black) that originated from a naval ship...
I know it's authentic Tannoy cause it says Tannoy right across it

And where do you think the name Tannoy came from (at Butlins and Railway Stations and I feel sure I've heard naval ratings use even if the officers don't) for public address systems?
"I've just heard this over the tannoy!"
