Juan de Posada, for instance, was an expert navigator who sometimes doubled as lieutenant governor for his brother-in-law Pedro Menendez Marquez. He once calculated for the crown that a good-sized galley, a 100-man fort, or four frigates would all cost the same per year: 16,000 ducats. Posada was bringing back a title of treasurer for himself in 1592 when his ship sank and he drowned off the Florida coast, which he had once called easy sailing.
