The primary goal is to help people who row or paddle (or sail) on the Hudson river (a.k.a North River). Other users may be interested. The current on the river is strong, so you need to plan your trip. The odd thing about the Hudson is that the river keeps flowing north (or south) some 2 hours after high (or low) tide at the Battery. Go figure. It is complicated.
