If I recall, that was one of the Delray guys and they went to Bimini and back in one day. They also did it dead reckoning. My trip will be two to three days to the Grand Bahama Island near freeport and I will have a GPS.
If you are doing round trip, it does not matter where you start you will be bucking the Gulf Stream regardless. I am starting and finishing where my boat lives. By going straight across, you are spreading it out evenly. I used to play out in the gulfstream all the time before we had kids.
The beauty of this is no ground support needed. Just a credit card and passport. If wife wants to come, she can take the cruise ship over and join me there.
