    Default 2 letter code Sierra November

    I've just been reading an old (1970s - not that old) sailing manual. In the signalling section it includes the 2-letter group SN. This means "You should stop immediately. Do not scuttle. Do not lower boats. Do not use the wireless. If you disobey I shall open fire on you".

    I'm dying to find a reason to hoist it - any suggestions?

    A passing jet ski perhaps?

    You could try flashing it the next time the septics park one of their nuke aircraft carriers at Pompey. Report back the response if you live long enough.

    It's the "`Do not scuttle" I particularly relate to!

    Or the new carrier. I'm sure they'd love a chance to use their new Phalanx CIWS for real!!!

    It seems the QE is doing a pretty good job of scuttling herself...

    I think, therefore I am. I am, therefore I sail.

    C'mon, it's only a leaking pipe union.

    Something the Health and Safety Executive reckons needs to be nipped up by 'a competent person' before being signed off. Apparently, there's no-one on board with the necessary Sustificates, so back to port she must come for a 'dockyard matey' and his team carrying 'no spark' portable barriers, Method Statements in quadruplicate, a range of tools and the briefcase of Certificates of Competence permitting their use by said 'competent person'.... and a qualified First Aider in case of attacks of the vapours.

    Or it could be the equivalent of Yossarian 'pulling' the intercom cords, so that they don't need to go to the Gulf of Oman and get shot at.

    Seems to be a lot about leaks in the news these days.
    One hull good, two hulls better.

    A navy ship bringing up another ship.
    the complete signal book is here http://www.seasources.net/PDF/PUB102.pdf
    SN is on page 83 section 4

    Edit: I would think that a German WWII raider would use this signal when stopping a civilian ship.

    I agree, but the thing which amused me was the inclusion of this code group, in a list of only 5 such codes, (JG, JH, SC, ZL, SN) in a main-stream sailing manual written in the 1970s (Stanford's Sailing Companion, 4th edition).
