Bro, you are fond of sending us all links to various histories. Well the fact that all the shipping was locked up by the New England/New York shipping industry just happens to be one of the things that you sent to me.
Do you not even read your own links?

"...the fact that all the shipping was locked up by the New England/New York shipping industry just happens to be one of the things that you sent to me." 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?
