I'm interested in this as well. We are starting a charter in Antigua and would potentially like to do the same basic thing. I read there is a customs office on Barbuda but it seems like a pain to get to. Would be nice to be able to check out of Antigua either at the airport when we arrive or at least at C&I before we head over to Barbuda.

Boatboy, I am going to be down there on a DYC Lagoon 40 starting in Antigua on June 18 and ending up at St. Martin on July 3. Will be myself, my my wife and our three kids - our first charter outside of the VIs. Feel free to stop by for a drink if you see us.
