From what I've gathered about Mexican (and possibly US) authorities, it might be a good idea for your delivery captain to have an official document showing that he has been designated to skipper your vessel for delivery to a specific port in Mexico. The more stamps, signatures and raised imprints the better. You wouldn't want him to be accused of piracy, and have the boat impounded en route. Issuing it in French might give pause to any over-eager Federales or Coasties too.
