The Coast Guard is cautioning tourists to avoid illegal charter boats for the upcoming Chincoteague pony swim. Officials say the illegal charter boats do not have licensed captains and pose a number of safety risks to passengers. The Coast Guard says it will aggressively enforce federal regulations and will inspect and cite boats that do not have licensed captains or boats carrying more than six passengers without the required inspection certificate. This year’s wild pony swim will be held on July 30th.
