This is just stupid. What kind of people invest in a yacht, anchor it
in a foriegn cove, and go to sleep leaving their important items all
over the place and things unlocked, as if they are in their livingroom?
And what kind of people commit this idiocy, and then spend all night
and the next day calling "mayday", and thinking it is something the
local police can, or even ought to try, to investigate & solve? But
worst of all, what kind of people go further and propagate all this
stupidity and ignorance all over the world?

Yep, it sure is getting dangerous - the increasing danger of idiots
with crusing boats, that is...
