Re: New York City
Sound like a fun trip but might be biting off a bit to much for a day trip. Lots of water there but unless things have changed, it is difficult to get to. Am sure others from the area can come up with current info for launching.
Do know there is a current ramp in CARTARET but that puts you in the middle of the ARTHAR KILL ( chemical coast, big ships, refinerys ). Nicer area might be the SOUTH RIVER boat club and cruise down the RARITAN. Trip from there to the harbor is do able as years ago a friend and I took my 12 ft. sears boat with a 7 1/2 aircooled to the statue from there. Dumb trip, young and full of beer. Launching from the KEYPORT or HIGHLANDS is something to also consider. Biggest problem I can see is towing in that area, very conjested.
Not familiar with the area north but might consider launching in the HUDSON at STONEY POINT north of the TAPPAN ZEE bridge. Think that would be more accessable with towing from PA. For a day trip, putting in on the delaware south of TRENTON and doing that area might be a better idea. Thats not like going to the city but would be a lot less of a hassel. Not trying to talk you out of it, my experience goes back to the 80s and am sure things have been cleaned up since then ( sunken barges, ships, rotting piers, 55 gal drums, lots of tires floating). Sure there are guys here that can give you better current advice than I can. regards FRED
