In THEORY it is possible. The theory is that you ride the tide out the Ft Pierce inlet, head
south no more than 1 mile offshore and ride the sea breeze south. I have spent a lot of time at that distance and can assure you that from Miami
to West Palm, the Gulf Stream current
is less than 1 Kt at that distance offshore. IF the winds stay pure east,then you could make it there....
Okay now reality. From Ft Pierce the next inlet you would probably use is Lake Worth
(West Palm Bch) - easy pickens- if the tide is right... and if there are no ships out/in bound. South of Lake Worth
the next one is Boynton (not usable for sailboats) then Boca (not doable without a motor), Hillsboro (I think dicey without a motor), then Ft Lauderdale- (another easy one...if the wind
& tide is right and if no ships operating). Suffice to stay, without the motor you are almost 100% committed to staying outside non-stop. So picking a weather
window will be critical.
Next I would look at the historical winds- they may not cooperate in directions or strength. Without a jib you could be forced to tackout further than 1 mile thereby increasing the Gulf Stream's impact on VMG.
The best advice I have seen is getting a kicker
, or if there is an inboard there are some good mechanics who will work at a reasonable price
. Short of that get a crew with very good skills and BIG "ballast."
