L'Eau Commotion Westabout

Day 75 8pm Wednesday 21st August 2019 ( UTC +1 )
As predicted the wind became quite light so after breakfast went about setting up the BiSymmetric. As the wind became even lighter during the day I lowered the main completely as it seemed to be interfering with the airflow to the Port ( Red! ) part of the BiSymmetric and we are now just ghosting along making 4 knots in a barely perceptible breeze. It was a bright clear sunny day though still quite cool due to the Benguela current which, I am advised, is adding half a knot to my speed. Also of interest I am picking up vessels out to 192 miles on the AIS which I guess could also be related to its cooling effect on the lower layers of the atmosphere. The normal range for ships is around thirty miles but again this can be as little as eighteen miles. I was passed yesterday by one of the ore carriers on the Brazil China route and she was truly enormous, measuring 361m by 65m beam and draft of 21m which in round terms comes out at close to half a million tonnes!
