Re: U.S.-Bahamas, Crossing the Stream
We ran typically from 7a-5p down the ICW, going about 6 knots @2500rpm. I do believe we could have ran 6a-6p and gotten +75 mi in a day, maybe even 100 mi with favorable currents or running the motor harder. We had planned of 50mi/day, so 75 was plenty good.
We could certainly do an offshore run from SC to Jacksonville, FL and stay inside the Gulf Stream. In fact, it looks like there is a counter-current running right off the coast in that stretch (this info. comes from buoyweather.com, but passageweather.com is a good free resource). After Jacksonville the Stream gets closer to shore, so I'm not sure you could run down the coast beyond there without fighting current the whole way. My research suggests after Jacksonville we'd want to go back inside to say Lauderdale, but I don't have experience in those waters so I can't say for sure. I'd imagine other members of the Forum would be of greater assistance with that question.
