Hi, Welcome to Sailnet!
That is a trip (up the Hudson to Montreal) that we hope to do some day.
I have learned quite a bit from Sailnet member "Labatt", who has made parts of that trip a few times. He is out cruising with his family, so doesn't pop in too often anymore, but you might search on his username and see what you can come up with.
Hopefully others will chime in too.
