Danforth anchors do well in the soft mud and even clay of the Hudson river, mostly. When the current changes it could dislodge fairly easily and not re-set. That is why I suggested doing an anchor watch if anchored in the river anywhere near the main channel.
Your home port is Orient Point? Now I am even more jealous! You'll get to do big lake sailing, canal motoring, Hudson river on into the Sound and out to Orient.
There is one pretty safe anchorage I know of on the lower Hudson. If you use google maps and look up 'Bowline Point' you will find a protected bay just south of Haverstraw. Folks also anchor near Croton Point on the east side of the river. It is about 30 nautical miles to The Battery (NYC) from there.
The Tides and Currents website of NOAA is very useful for guidelines of how fast the current might
be running up and down the Hudson. Be aware though that heavy rains and strong, consistent winds can also effect the tides and currents on the Hudson.
'Freshets' are small floods caused by either melting snow or heavy rains and cause a more then average down river flow. Winds can also slow the tides and mess with the currents.
The website I linked for you only shows 'predictions'. If the weather is really bad from one direction or the other then all bets are off and you can throw the 'predictions' out the window. It all depends on when you go, what the weather Gods give you and how you accept their offerings.
Not long ago the Mohawk River valley got record rains that messed with the Erie Canal system.
My experience tells me to expect that the 'norm' is mostly the case.
Have fun planning this trip.
I'm new to these boards so I hope my thanks some how reaches everyone. I very excited for this trip. This is my first serious cruise. My end destination will be Orient Point, Long Island where I grew up and learned how to sail. I decided to buy myself a boat for my 40th birthday and to stop putting a dream.
Thanks for the information CalebD, thanks for the tidal info. I feel more reassured that my motor will be able to handle the river. Many Contessa 26's have more powerful Yanmar motors but my feeling is that the little Kubota will do me just fine and perhaps be less problematic. Also I think it will be easier to find parts if needed in the future.
