Bob;
There is very few go fast in haverstraw, and really not much of a concern. There is one or two in particular, and when they "idle" out to the river, it really doesn't matter where your slip is.
Most of the time its a very quite marina. Being known as a transient marina though, we get a number of large groups that come to party. They are usually a little loud their first night and then seem to quite down after that. At least until the hangover medicine kicks in.
