CYOA in USVI doesn't start charters on Sundays, although they may accommodate quickly meeting you to start a sleep-aboard. If the charter company does it correctly (like CYOA does) your boat briefing and checkout can take many hours and the staff needs one day off with family. Definitely check out CYOA as you consider your options. I don't often vacation in the same spot twice, but CYOA's quality operation makes a return trip very appealing.
