[Flagship, eh? Barbossa didn't have quite that (not that he would have it be otherwise), but still - Marco's fortunes might've been even worse than his own.]

Well, isn't that interesting... Captain Marco. Impressive, if true. What color were yer sails, I wonder?

[It sure sounded like he didn't come from the world he had known, so it got him naturally curious as a fellow pirate captain. And also, he wanted to find out more about the validity of what Marco was telling him. Naturally]

Ye're certainly correct that it's all moot. Me own ship better be intact when I return, though... If that's possible, given our new friends, the Malnosso.

[So on top of this barrier would prevent him from seeing anything close to the vast open waters he was used to.]

I gather that there is no outlet to sea close by that we may head to, at all, then?
