Flag for Americans born on the Atlantic Ocean

Most Americans are born in the USA, some are born abroad in foreign lands by Americans living abroad.  But still a few are born at sea.  This flag is for Americans born on the Atlantic Ocean.

The flag for Americans born on the Atlantic Ocean uses the colours red, blue, and white.  In the upper hoist area is the famous Betsy Ross Circle of stars to denote connectivity to the United States.  In the 1600s, 1700s, 1800s and early 1900s there were hundreds of Americans born at sea on a ship, since this method of transport was extremely slow and the only means of intercontinental travel.

In many ways the Atlantic Ocean is the ocean that gave proverbial birth to the people of America who would come to dominate the American Continent undergoing a metamorphosis from African, European and Asian unto becoming a new people - American.

Flag for Americans born in the US Exclusive Economic Zone

Believe it or not, there is an exclusive minority of Americans born upon the sea.  Some are born in US Internal Waters, while others are born in the US Maritime Contiguous Zone, and finally at the very tail-end afterglow of American spaces - we have the US EEZ - or rather the United States Exclusive Economic Zone.

These situations arise when an early unexpected birth takes place at sea, usually upon a cruise ship, transport ship, refinery, or yacht.  Thus a person who has at least one parent or grandparent with US citizenship, can fly this flag so long as they they were born 24 to 200 nautical mile out to sea in the US Exclusive Economic Zone. 

Although the US EEZ starts three nautical miles out to sea, this flag is for Americans who were born 24 to 200 nautical miles out to sea.  Reason being, citizens born from 3 to 12 nautical at sea are officially born in US territory at sea, thus they can fly the US Internal Waters flag; while a persons born 12 to 24 nautical miles out to sea miles use the US Contiguous flag. 

The colours of this flag are based upon the Exclusive Economic Zone flag combined with first proposed and vexillological US Internal Waters flag.
