I can help you with the weather
http://www.opc.ncep.noaa.gov/ is a good link to have if you cruise.
Here is what all the stuff says for Sunday...
average sea state along the east coast is 3 to 6 feet or leass and that goes from NYC to FL Keys out to Bermuda. Winds will be SE 10 to 15 knots.
Hope this helps you out and have fun.. I will be cruising the Spirit next month. Cant wait to hear about your experience.
