I spent a couple of weeks sailing in and out of there last fall. The whole crew really enjoyed the harbor amenities: nice restaurants, provisioning
(French-YUM), all the yacht services you could want including "high tech".
Nice full size airport
with good international connections including an AA non-stop to Miami
Plenty of short sail destinations: Îles des Saintes, Marie-Galante, Deshaises, and St Anne, with Dominica
, Montserrat full day sails
. Very easy clearance in and out via computer.
I wouldn't hesitate to base there.
