    That has already been done. Collectively they are called IMO and SOLAS
    regulations.
    Most shipping countries in the world are already signatories to these
    agreements.

    REPLY
    It's already included in the ITU and IMO regulations. Actually the new
    regulations now call for Ch 70 to be the digital monitored frequency in the
    mandatory GMDSS radio systems used on all SOLAS compliant vessels.
    And in designated sea areas CH16 is also monitored.

    REPLY
    Something similar is already a feature of GMDSS radios.
    Also remember those shipboard radios with 4 sectors marked in red in the
    dial.
    These representedthe radio silent periods fro watch keeping for emergency
    signasl.
    The watchstander timerI mentioned way back at the beginnign of this thread
    is compulsory for commerc9ial craft in some countries. Like Canada for
    instance.

    Already been done. Its called AIS.
    Various versions have been sea-trialed by many countries around the world
    before IMO sanctioned a specific system. Its mandatory on SOLAS class ships.
    I witnessed some sea trials as long ago as 1993.
    Back then it was a hot topic in maritime engineering magazines speculating
    about future technology.

    REPLY
    That's exactly what you get when AIS is integrated with ECDIS.
    Check out www.aislive.com for a sample.

    Most of the world has already adopted these suggestions. Its only the
    recreational boaters of North America that has a problem with it. The
    problem in the US; somebody will holler about infringement of their
    personal freedom or they complain it will cost too much, or interfers with
    their own choice of toys.

    If pleasuer craft had to conform to small commercial vessel standards ther
    would not be a problem.
    Nor would there be a problem if everyone actually followed all the rules.
    Unfortunately, there will alwaya be individuals who figure the rules do not
    apply to them;
    or that their personal situation justifies breaking the common safety rules.

    The most basic set of these rules is the International Collision
    Regulations.
    Just look at the vehement defence for singlehanders to ignore Rule #5.

    The ITU (International Telecommunications Union) has rules governing how
    radios are operated, which frequewncies are used and what the official
    language is. By international agreement it has been agreed that ENGLISH is
    the only language used for radio communications worldwide in international
    waters or air space.
    Despite this rule countless radio operators use other languages or are
    incapable of a working level of english when calling into North American
    ports. Just ask any VTS operator in a busy entre-port.

    So how many more rules do you propose to make, that will also be ignored by
    a lot of people? <VBG>

    regards
    Arild
