I'll hail this ship by it's right name on vhf70 or call it by dsc
using it's unique mmsi-number. After identyfying myself and my
position we'll discuss and verify the probably one and only right way
to avoid any risk of a collision-course.

Here in the Netherlands the government is contemplating making ais
mandatory (also for 300t vessels and indeed also for yachts) cause
freigthers increasingly tend to use ais as sole informationsource over
radar. This is imo a good development. Ais will work 100% when
everybody, everywhere uses it. One might expect these rules will find
their way into supernational legislation.

Len, following your post about AIS Live I went to check into what was
active in my cruising area, the Adriatic. Zilch - zero - nada - not a
single AIS equipped ship was reporting in the entire Adriatic Sea,
although clearly the system was active as there were a few clusters
around Malta, Athens and Marseilles when I included the whole Mediterranean.

Now I know there are masses of freighters and large ferries converging
on Trieste, Venice, Rijecka, Ancona, Bari, Split, etc, etc. every day of
the year, indeed, I had a hair-raising close call with a monster, 50
knot, catamaran ferry 10 nm off the Croatian coast last year - but it
would seem that AIS would not have helped me.

It is likely that all the small companies that can avoid installation
until the mandatory 2008, under whatever regulations they fall under, or
are illegally avoiding installing, or the crews are not bothering to
activate if they are installed, are doing so.

Best,
