I agree with PB, if you are in a rush it makes sense to go outside but that assumes the boat is sorted out and ready for it. I would go through the C and D and Delware Bay and then outside to New York. With a really good forecast and the boat working well you can stay outside, but in general I would be inclined to go into NY harbor and then through Long Island Sound and Cape Cod Canal. A pleasant trip with many worthwhile places to visit on the way.
In South Africa doing lots of boat stuff. Departure north from Cape Town around December 15th. Arrival in the Caribbean around the beginning of February, after 5300 miles or so.
