Do not rely on the ferries or inter-island "mailboats" as they used to be called. There is no guarantee that that the boat will arrive or sail as scheduled. The boats are a vital part of the Bahamian economy but lately due to fuel
costs and government
imposed rates they are sailing less frequently than before.
We were in Staniel Cay this season and stayed an extra day waiting for the mailboat to come in with fresh stores. The boat skipped the trip that week so we waited for nothing. So we moved down to Black Point as their boat was due in a couple of days. We waited and it did not arrive. For two days it was "coming tomorrow" as it was in Nassau waiting for spare parts
. The boat did not come that week at all.
This is the way it is. Everybody lives with it. If you are stuck on an island and have to get out your only way out is to charter
