NYC boat cruises?

no one

A guest on one at least?

I have been on a few that were okay. There is one gorgeous boat I went on...I think it is called the Bateaux New York. It is flat and has sort of a green house type covering of all glass. Oh, and I was a guest on the boats so I don't know the costs; sorry.

ETA:

I've been on the World Yacht and FH proposed on Le Bateux - Both were great.

World Yacht is more of a party atmosphere.
Le Batuex was a romantic atmosphere. Everyone there was celebrating a special occasion and two other couples besides us got engaged on that night.
