I believe the Warren St. marina is managed by someone out of the adjacent condos. A guy I know from LH went there for a year after Sandy and then came back to LH. I didn't ask him about his experience. Just my impression, but the Warren St. marina always seems crowded and a bit unfriendly to me.
I keep on wanting to move my boat to LL, but LH is more convenient for me as I live walking distance. LH doesn't allow liveaboards, if that matters to you. Out of principle I dislike marinas that are anti-freedom which is how I see that issue... even though I live in an apartment at the moment.
There are some friendly, nice sailors at LH, and most don't have much positive to say for LH management if that tells you anything.
NYC marinas are all about trade-offs, kinda like NYC housing.
