ohh ok
i was imagining that was all a single straight line candidate
but evidently you mean there is a deflection
between neck & lagoon
clearly we need a trustworthy map to play this game seriously
as well as a truly answerable question
but i will leave the questions to the questioners

great so we have an 11km candidate at least
& it looks like one could come up with a hard number for the
index of the straightness of this or any other entire boundary
within any specified degree of yaw allowance
but it would still be compromised by that lovely fractal absurdity

yes & i dont know but that the more seaward or terminal
monument may not be a turnpoint at all
but rather only a waypoint on the terminal projection of the
boundary line thru it
but originating from the penultimate monument
this is after all what commonly happens seaward of terminal
monuments
so perhaps you could add 12nm of territorial waters to the final
reach
but yikes that makes every maritime reach of every international
boundary in europe a candidate too

right but depending on what jespers question actually is
we may actually need to define the threshhold between

good thanx
it was a good one then
maybe we need to know what his exact question would be too

yes no problem with its europeanness
& i have a 1981 atlas that gave me hope of there being a long
straightaway there too
but the latest maps at perry castaneda seems to dash that
