"all is cool but ham is for a earth station, and not for marine use"
The
regulations about marine
radio use have nothing to do with ham radio. Ham radios can be, and regularly are, operated from fixed stations, marine stations, aeronautical stations on aircraft, rockets, and balloons, and even from the International Space Station (ISS) and unmanned ham radio satellites.
All perfectly
legal, all covered under every class of ham
license. A ham radio can be legally operated anyplace that the control operator can get the radio to
work from, and that his
license is geographically valid by US law or ITU (reciprocal) convention.
Now, if you have ham and marine radios both installed on a ship, the laws may require separation of the
equipment, depending on licensing and certifications of the
equipment and the operator.
But ham radio being unsuitable, illegal, or improper in marine use?
ROFLMAO!
In fact, the regulations have loosened in recent years and it is no longer necessary for a ham operating in the US to use region designators, or to call "mobile" "portable" "aeronautical" or other modification when they are identifying their station. As they say in the big gray ships "If you got 'em, smoke 'em!"
You've been badly mislead.
