An interesting picture. The rust colored quadrants are bad wind directions because of the Gulf Stream. The red arrows are wind on the nose for the worst crab across the Sream from West Palm (The boat has to crab as much as 45 degrees in the strongest flow of the Stream.) The green arrows are the best wind direction for a fast comfortable ride. The blue dashed line is the rhumb line between West Palm and Memory Rock. This year has actually had more “good wind” than the last two, but the heavy northerlies have left swell behind that made the “good wind” days this year pretty much unusable. Half as many calm days (2012-2014) have also reduced the opportunity for the seas to drop. Wonder what February will reveal?
Each arm of these roses is proportional to the amount of wind of that velocity from that direction. None of these even come close to what the Pilot Charts indicate one should expect in this region.
