Thefts in Zihuatanejo

The cruisers here in Zihua are unsettled and with good reason. Two days ago, two boats were burgled during the closing ceremonies of the Zihua Sailfest. Reports are that a third boat was burgled a few days before then.
Thefts happen here in Mexico, just like everywhere else. It's not a common occurance, but every month or so, you will hear through the SSB radio nets of a cruiser being robbed. Almost always, the boat is anchored in a city (most often on the mainland). Usually the theft is of items left unsecured on deck or of a dinghy left floating behind the boat at night. These thieves never set foot on the cruiser's boat, they take what they can while staying on their own boat. They don't want a confrontation and usually work in stealth in the cover of night.
What makes these thefts in Zihuatanejo so unsettling to me is that the locked boats were boarded and broken into in broad daylight in a crowded anchorage. Most upsetting of all, on one of the boats a knife was taken from the galley and carried around the boat while they were checking to see if anyone was home. Thankfully, no one was. I've heard of boats being boarded two other times in Mexico this year. Both happened during the day, when the boats had obviously been under surveillance and the crew was known to be off the boat. I have just never heard of thefts against cruisers in Mexico involving the use of weapons and potential confrontation.
Reports were made to the Mexican Navy and the Port Captain. Both agencies appear very concerned. The Mexican Navy has begun patrolling the harbor and anchorage and have been a presence since the incident. Thankfully, we have Rudy on board. He may be a marshmallow inside, but he's scary looking on the outside, especially in a culture like this which tends to fear dogs. He's big, has big teeth and a big bark. It's nice to have a little extra insurance.
