In contract on a 48da located on lake Champlain - plan is to run her early May down the Champlain canal into the Hudson. From there through the spuyten duyvil into the Harlem river, through hells gate and into the Long Island sound. Looking to get her home in 3 days which I am told is doable. Any comments as to my nav plan (i.e. - Harlem river versus going around bottom of Manhattan) as well as recommended marinas for the 2 evening layovers appreciated. Thinking the stops are around lock 5 and then somewhere around tappan zee bridge. I was told I should only need one bridge to open in Harlem river - if anyone knows otherwise it would be appreciated. Thanks.
