I have not disputed "there is no evidence" if you care to read my post.

I clearly stated that the accounts of the voyage were written years after the event, in case you missed it I said "Later Christian writings suggest he did so, but they may well be biased"

"Odd isn't it that others who did make the journey left archaeological traces of their having passed that way. St. Brendan and his pals did not"

None that we know of, the Eastern seaboard of North America is huge, evidence could have been destroyed by later settlers ......... who knows.

As for 60 men ......... let's see ......... more than one boat perhaps.

But like I said Hey it's a good story.
