Santa Maria ... No

UN investigators have found proof that a shipwreck found off northern Haiti in 2003 could not be the Santa Maria, the lost flagship from Christopher Columbus' first voyage to the Western Hemisphere.
Uncesco said a team of experts who explored the site at the request of the Haitian government determined the wreckage was from a more recent vessel for reasons that included the discovery of copper nails and spikes at the site. The Santa Maria would have used components of iron or wood, the agency said.
