Did Croatians settle in America before Columbo?

[Anomalocaris]

There is, as far as I know, little or no doubt the Vikings settled America in the Middle Ages, and I see no reason why that can't be true for Croatians. 

The Vikings largely island and coast hopped from North sea to Iceland to Greenland and then to Labrador coast.  On this route they needed only to make relatively short open ocean traverses of a few days.    


A trip out of Mediterranean to North Americas would requires enormously greater open ocean traverses of many weeks, even if they touched on the furthest island off the coast of Africa.    In addition, the very nature of North Atlantic sailing is a different ball game from Mediterranean sailing.  

Are there any evidence Croatian sailors made any extensive trips outside of the Mediterranean during the period, let along exhibit the ability to stay at sea for weeks on end?
