That map you post endlessly proves no such thing.
I shows that regardless of who owned & operated various *export* shipping, returning ships found it convenient to land and pay tariffs in New York, that's all.
Everything else you've extrapolated from that is pure unsupported speculation.
Or were you referring to something else?
I didn't suggest that it did. I said the links you have posted several times, proves such a thing. I asked you why you didn't even bother to read your own links relating to shipping out of New Orleans.
It out and out says virtually all the contracts and shipping were controlled from New York. Do I need to hunt it up for you, or can you find it from what I have told you?
It is the link about the flat bottom boats. Look it up.
