Another day of sailing with all six sails up and no motor. At 0900 this morning we clocked our first 200 nautical mile day averaging 8-10.5 knots over the previous 24 hours. The wind has been tricky today, but in general we have kept at about 7-8 knots. Today we had our last Marine Biology class before the first exam on board Argo. We learned about sound signals, lights, right-a-way, and buoys in our Basic Seamanship class. The best thing on board is sailing silently in the middle of the night.
