The “Bimini Mack” (Mail Boat) goes from Nassau to Cat Cay & Bimini
(departs Nassau Mondays & Thursdays, fare $45).
The “Captain Gurth Dean” goes from Nassau to the Abacos (departs Sundays & Fridays , fare $45).
Perhaps one of them will stop in Chub?

As Rick notes, it’s an easy (<40 nm) sail between Chub & Nassau.
