My map isn't fine enough to give a precise distance (I'm working from 
Prescott, of which/whom I'll try to produce a scan next week), but 
20nm or so seems right. Saints Martin and Bartholomew form a little 
exclave of the French exclave Gaudeloupe; bordered by Anguilla, 
Antigua & Barbuda, St Kitts & Nevis and (of course) the Netherlands 
Antilles. The tripoint with Anguilla is tight inshore, as you say.
Hmmm. I've missed and unwittingly revisited several things in this 
group already. But nothing daunted ... do we have a name for an 
exclave *of* an exclave? 
No dry land examples, for sure, but at the EEZ level (what else?) the 
top of my head offers (in addition to the Gaudeloupe example above): 
Bassas da India + Ile Europa + Juan de Nova (Reunion [France]); Iles 
Glorieuses (Reunion [France]); Ile Clipperton (French Polynesia 
[France]); Ascension (St Helena [UK]); Tristan Group (St Helena [UK]).
Ile Tromelin is also a Reunion dependency, but its EEZ merges with 
Reunion's. 
Do any other countries but Britain (definitely) and France (I think) 
acknowledge such sub-let dependencies?
