Peregrinus is legally a British ship. At the time we bought her, no other registered flag was available to us that would make it easy for Peregrinus to travel in and out of the United States. So after some paperwork, she was registered in the Virgin Islands, and she either flies the Red Duster undefaced or defaced with the coat of arms of the Virgin Islands.
In addition to meeting the laws of the countries on whose waters she navigates, Peregrinus must meet the UK's Merchant Shipping Act of 1995 as well as the VI's Merchant Shipping Act of 2001. Fortunately, these two agree in all matters of substance!
