Post-Irma, ferry schedules are completely different: several aren’t running. Couple that with the fact that this is hurricane/low season, and you can expect even more changes to the ferry schedules. The best place for up-to-date information is the Facebook BVI Community page.

From West End, you can only get to Jost, never Anegada or Gorda. Pre-Irma, you could go to St. John and St. Thomas, but those links, AFAIK, aren’t running now. WE was also badly damaged, so that seems like a poor choice to stay.

Anegada ferries were going from Trellis, but aren’t now, again AFAIK. I think there are thrice weekly ones from RT. Gorda ones leave from Trellis and RT. Your best bet is staying in RT, probably at Maria’s. Many restaurants will be closed in September, so that is your best option for finding open ones.

As far as Anegada, flying up on VI Airlink is by far your best choice for a day trip.
