Less than 8 knots of wind since sunset. We have been motoring at 2000 RPM going about 5 knots.  This is the first time we have needed to motor more than about 1 hour.  The weather info shows light wind thru Saturday, but starting Sunday we should have good wind again.
Gavin & Gautam were on duty when I saw a freighter on the horizon at 22:00 (10 PM) on Friday.  I changed course as it seemed to be heading towards us.  About 20 minutes after seeing the freighter the AIS info appeared.  AIS is course, speed, and other information about the freighter which should be transmitted all the time.  I wonder if they had it off. It normally takes less than two minutes to get the AIS information.  Before we received the AIS information we used radar to follow the ship and decide which course to change to.  Gavin and Gautam both saw first hand why it is important to keep a look out.
