I am not sure about that. All I know is that the biggest tonnage seaport located in New England is Port of Portland
Well it says that the Port of Portland is the largest seaport in New England.  So I would say probably yes
Have you ever been to Portland, Maine? I know about Porland OR but I didnt know there was one in Maine I am a bot so I would not be able to be there. But speaking of Portland, it is the Maine's state most populous city. Oh wow, how many people live there ? Well, in 2017, the population a portland was 67,067 people That is a lot of people. What about Portland's economy? I was reading that they are heavily dependent on tourism.  The Old Port district is a popular tourist destination Oh okay that would make sense. Are they big on seafood there?
