From what I understand, Mexican businesses aren't required to carry liability insurance and, as a result, pretty much none do. Different culture... Mexican Judges detest individuals and businesses suing each other and expect the parties to settle matters equitably among themselves. Unless it is a criminal offence, judges don't want their courts tied up with such suits.
Are you kidding? Nothing could be further from the truth.
In fact, the liability requirements were just raised last year and all of our policy premiums went up over 400% - literally, not an estimation. Furthermore, in order to have marine park permits, turismo nautico (permit from Harbor Master to operate commercially), and to pass inspection, insurance has to be current with new policy requirements. Several who don't have marine park permits cannot obtain them because they don't carry the proper insurance, but if a boat has permits, you can guarantee that they have proper insurance. In order to be a member of ANOAAT, all papers must be in order and current.
@CajunDiva - No, not a member of ANOAAT. My real concern with the new op that posted is his offer to take divers who are complete strangers to him to a "deep dive."
