We should by now be bowling along downwind, enjoying 15-20 knots of SE Trades....so where did the SW 10-15 come from?
Still the sun is out and the water getting warmer so not all bad! I think we are loosing the race with the others, they have all left us far behind in their wake, hopefully they will have cold beer ready when we eventually arrive!
