Re: Miami to Bimini
What you are missing is that you need to wait for the right weather window, both going and coming. You cannot count on having the right weather to cross both ways within a single week. And trying to cross the Stream in that boat, in the wrong sort of weather, can get you killed. That is no joke, and it is not an exaggeration. People have died trying to cross the Gulf Stream in the wrong sort of weather conditions.
If you want so sail in the Bahamas, charter. If you want to cross the Gulf Stream, wait until you have a month or more so that you can trailer your boat to Miami and then hang around until the weather is right, go across, and then hang around again until the weather is right for coming back.
Trying to do this sort of thing on a tight schedule is a good way to get yourself into SERIOUS trouble.
