grant

thank you very much indeed for demonstrating these cool cooddities



& i think all their 12nm lines also must take a similar jog

tho in that case the gap is filled in the diagrammed example at least by chilean eez



but it is also good to focus on any or all of the 3 peculiarities because they do so effectively dismember the otherwise predictable binational quadpts you find so negligible into even more ignorable tripoint pairs yet without at all displacing or otherwise disturbing the underlying everyonese tripoints



this special behavior of these boundaries makes me want to complete our already well begun roster of them & more especially so because i cant think of any other examples of their type in the world than just these very strange 3 in a row we are looking at here
