I have never been out of the U.S. coastal waters on a boat yet. Several

of my friends and I are planning an extensive world cruise in two
years. All of us have had extensive training in the use of firearms of
all types and we all enjoy shooting sports as a hobby. We all like
trapshooting so we will have at least 6 shotguns plus a few thousand
rounds. Add in personal weapons and there will be an extensive arsenal
on board. I know some countries absolutely prohibit personal firearms
so we will have to take precautions in certain waters. Mexico is one of

the most prohibitive I understand. Since we don't want to have an
international incident what procedures are best in a situation like
this? I have suggested we build a couple of watertight capsules for the

weapons and ammunition. With GPS and the appropriate eqipment we could
drop them overboard when entering restricted areas and then retrieve
them later. Are there any better but legal options that could be
followed?
TIA,
Dennis
