This has not been entirely my experience yet... I have seen a condom floating in the water, but I haven't really been bothered by it yet. No weird smells yet, but the water is usually muddy. And god, the mosquitoes are radioactive!We were at Liberty Landing for about two years, and if you want to be on the Hudson in proximity to NYC, it is one of three choices. I can happily say I'm gone. It's in a nice setting in Liberty State Park. However, it is a dead end portion of the Morris Canal and doesn't flush very well. Combine that with the fact that Jersey City hams a sewage overflow at the back end of the canal that pumps untreated, or at best partially treated, sewage directly into the canal, and it gets ugly. It stinks, sometimes gaggingly so, there are condoms (Coney Island Whitefish) and tampons floating everywhere. There is no pump out boat during the winter and the fuel pier pump out is usually not working in the winter either (no heat trace on the line so it freezes up). This effectively means that alot of people pump overboard so don't be surprised at brown sharks floating around.
The marina management leaves alot to be desired. Not very responsive. It was sold to some Texan marina group that want to turn it into a mega-yacht haven, so some of the amenities have been improved slightly. Maintenance is a joke, predominantly fixing what's broke and that's it. The yard, boy, I never had any work there and every single person that I spoke with that had nothing good to say. That included one of the old marina ownership's lawyers. Most of the slips do not have a center piling so you can't get a proper four-point tie up, if you care.
The good stuff: Ferry to Manhattan leaves right from the dock (by the lightship), the park is great to get out in. Jersey City is a 15-20 min walk with lots of good bars and restaurants. Parking is never an issue.
The other options are in Jersey City near the PATH station, I can't remember the name, but you can see it on google maps. Not a whole lot of water in there, 5-6 ft. The other is in Weehawken just north of Hoboken. It's in a kind of business, hotel type area, not very scenic.
Hope that's helpful.
