Bahamas aren’t in the Caribbean. But many of its reefs are badly affected by SCTLD. To the best of my understanding, SCTLD has not yet been identified off the south side of Cuba. I do think that it can be a challenge to get squared away with the liveaboard operators operating in Cuban waters. However, the number of people diving there is tightly limited. By all accounts (including tursiops’s) it is a very special place for diving.
