I am at the Worlds Fair Marina and I am thinking of taking my 23 ft. ODay through Hells Gate, either Feb. 17 or 18, 2012. Much of the postings discuss going towards Throggs Neck or the Battery. Is it possible to go into HG, check out the skyline, and return without going towards Roosevelt Island? Just make a U-turn there. Safely. If so, what tidal report should I use? Thanks.
