yes they have had one that detonated, 2 bomb-scares phone calls & found 2 more. Altho many politicians, CEO's vacation in that area (usually with their yachts) the general consensus is that this has to do with Roberto Borge the ex- governor from Cozumel who is awaiting trial for illegal land deals while he was in office. He owns the BarcoCaribe ferry which had the initial explosion which was said to be mechanical- but obviously not but everyone knows the papers lie. Once on the island of Cozumel there is no way off other than airport or the ferry. Trump was involved in land deals there about 14 years ago which never panned out blamed on 1) local protests over the sale of federal and environmentally protected lands 2) Trumps decision to pull out after viewing the damage after hurricane Wilma.
