The Aves Island claim must make Venezuela a contender for the largest 
number of maritime boundaries. Heading clockwise from Colombia, it 
has treaty lines or equidistance lines with: Colombia, Dominican 
Republic, Aruba (Neth.), Netherlands Antilles (Neth.), Puerto Rico 
(US), Netherlands Antilles (Neth.)[again], St Kitts and Nevis, 
Montserrat (UK), Guadeloupe (Fr.), Dominica, Martinique (Fr.), St 
Vincent and the Grenadines, Grenada, Trinidad and Tobago, Guyana.
15 separate boundary segments, 14 political entities, 12 countries.
(St. Lucia might also have a short boundary segment squeezed between  
Martinique and Grenada - on my map it looks like a quadripoint, but 
that's vanishingly unlikely.)

Yep, the borders with the US, French and Dutch dependencies are all 
defined by treaty. None of the others are.
Aves actually blocks a very interesting mishmash of equidistance 
lines from the various states of the Lesser Antilles - were it not 
for Aves, they'd all converge on a patch of ocean just a tad SW of 
Aves, in a marvellous punctoscopic scattershot that could keep us 
amused for years.

Interesting, because Antigua and Barbuda is on of the states least 
likely to be affected by the Aves claim. Its maritime territory is 
squeezed out of existence to the SW by a funnel formed by 
equidistance lines with St Kitts and Montserrat, both of which lie 
just a little SW of A&B's Redonda Island, and therefore a little 
closer to the Aves claim.
