Tropical Storm Sean is still active in the North Atlantic Ocean but moving very slowly and I do not expect that it will have much effect on the weather around Florida. It will be a breezy day but that is nothing to worry about. For the time being, the weather is great, we are sailing between the Bahamas and Cuba and the numerous islands, reefs and keys are really doing a good job with taking the momentum out of the windy weather coming from the North. The only thing that I do not like is that the wind has already turned to the NNW. And that means it is a head wind and I am losing the free knot of pushing current that I had hoped for. The area North of Cuba normally has easterly winds, part of the flow generated by the trade wind system. If that flow is not interrupted it nicely starts to push the water to the North West and that gives the ship a knot to 1.5 knots of extra speed in the back. As soon as that wind stops, the current diminishes and if the wind then turns to the West or North West, it falls away completely. The ship loses that free speed and instead has to start heading into the wind. This was the case today and now I was not saving fuel but spending it, as the ship now had to push harder while going against the wind. Hopefully I will get some extra free speed tonight when we enter the Straits of Florida, although with the NNW wind blowing there, the Gulf Stream might not be running that fast as with following winds.
