Send them copies of your cruising permit
, one per crew member
. The authorities will accept that to show that they intend to leave the country on a boat. The authorities being the airlines lol.
They can then buy a one-way return ticket in the Bahamas
and use that to go back to the states.
Remind them not to forget their passports. If they don't already have them they should get them way ahead of time, sometimes the process can take a while.
I just noticed - you and your boat are in California
? Or is your avatar out of date? If you are chartering a boat in the Bahamas I do not think there will not be a cruising permit
involved, so it's back to the round trip ticket.
