Laura, Fred and list, On the Hudson, low tide and slack current may not be at the same time of day. Also, flood only lasts about 5 hrs, while ebb lasts 7 hours. Similarly true on most River Estuary Systems. Several years ago, a friend put me onto this website: http://hudson.dl.stevens-tech.edu/maritimeforecast/. This is the maritime college at Stevens Institute. Its the best model of its kind anywhere. What you want is their analysis of "surface currents." Start with the NY Harbor Estuary (http://hudson.dl.stevens-tech.edu/maritimeforecast/maincontrol.shtml), and then work your way up the Hudson. It so accurate, in most places, you can run in the northbound eddies against the ebb current and still be OK. Not true in the East River, but true in the Hudson Valley.

If you have an iPad or iPhone you may want to check out the "Garmin blue chart" app. The app is free and for $49 you get all the US charts as well as complete tide and current tables. They are very easy to use.

This is the maritime college at Stevens Institute. That's an excellent web resource, and thanks for linking to it. Though as a proud Stevens alum, I will clarify that Stevens does not have a maritime college. That might be something of a loss for the community, because they are really quite good at it. The web site you reference belongs to the Davidson Laboratory, which is certainly a part of Stevens Institute, but it is not a teaching college. Stevens does not award any maritime degrees or credentials. -Sean m/y Vector on the hard in Deltaville, VA http://OurOdyssey.BlogSpot.com
