Great link, JRDelerious, thanks! Actually, if you read enough of this stuff you come to the conclusion that all of the proposed landfalls can irrefutably be ruled out. None of them matches in all particulars.

Columbus wasn’t even able to hit Hispaniola (his objective) directly on any of his subsequent voyages, even though he had been there before. On his second and fourth voyages, his first landfall was in the Lesser Antilles, and on the third in Trinidad. And such were the hazards of navigation in waters chock-full of coral reefs, he lost his flagship the Santa Maria off Hispaniola on his first voyage. On the night of the discovery, he was sailing as fast as possible westward in gale force winds, because he had promised his crew, on the verge of rebellion, that he would turn around if land wasn’t sighted in three more days. If his tiny ships had hit the Bahamas in the wrong spot, they could well have been lost with all hands.
