Mexico, and some alternatives
Here in Mexico, people have lost their boats due to carrying guns. It is not always a situation that can be remedied by mordida! That said, you do have some alternatives. In addition to your flare gun, or mace, I have always felt that a good shot with my blindingly bright spotlight (even during the day) might well do the trick, and I could probably buy a little time with a good blast of a little cannister airhorn, aimed in the right direction.On the dark side, I do have irrefutable personal knowledge of two SERIOUS piracy attacks, both about ten years ago. One was off the west coast of Baja, the victim was a Cheoy Lee 40, and the attacker a container ship...that is not a typo. It is a long story, but the ship approached in reverse from several miles away. If the victims had not had them on radar, they would not have known they were being approached, since the running lights on the ship made them look like they were going away (very clever). The big ship put two launches in the water, a chase ensued, eventually a Coast Guard Falcon jet showed up, etc. etc., and no one was ultimately hurt. I suppose the big ship wanted a sailboat, maybe for a drug drop. The DEA took a great interest in the case. My frineds now carry some hand made dynamite grenades (!!!), and never show lights. The other occasion was in Indonesia, and fortunately also ended up with no injuries, although it was a very near thing. Speaking for myself, I don't carry, and think it opens you up for way too much hassle (internationally, at least), but I understand those who do. I hope they have training, and I will probably be the one who brings them food and magazines while they languish in the care of some third world judicial system!My final thought is that incidents like I have mentioned are REALLY rare, and that cruising is one of the safest lifestyles one can practice, even without a gun. At least, outside the US!
