I have sailed out of NYC every Feb. since 2004. Been on the Gem 3 times. Sailing from NYC in winter is special you really get a sense of real travel. By the afternoon of the first sea day you have left frigid NYC behind and cruising in the Gulf Stream. The best cruise was the blizzard in 2006 on the Dawn. Absolutely unforgetable.
Lots of other pictures from NYC winter cruises and the Gem on my webshots. The link is in my signature or click on the picture below.
