I'm guessing that he might have been quoting SOG from a GPS and
getting some boost from the Gulf Stream. My old Cal-34 used to exceed
hull speed under sail fairly frequently however. It's not an absolute
limit, just a point where you need a lot more power to start climbing
the bow wave.


I doubt it. If he were headed north, then yes, but the Stream runs
roughly 90 degrees to the intended course here. I can't see how that can
add to speed made good. Maybe Skip will drop in and clarify.

It simply cannot add to speed (through the water) made good.
Hull speed is hull speed is hull speed on a displacement hull.
No amount of current from any direction can change that.

Set (current) can only add to or subtract from speed and distance
(over ground) made good.
