Headed home…

We’ve left for home and are heading across the Drake Passage.  We should be at the dock by Wednesday morning.

This is the rudder mechanism for the port side rudder.  The two big blue pistons spin the shaft to move the rudder.  When we transit the ship is put in auto-heading.  This is a mode that lets the ship steer itself.  These rudder pistons are constantly moving to change the rudder angle and keep the ship on the desired course.

Here is a photo looking out the front of the bridge. The view is great, but you can really feel the rocking motion of the ship this high above the water. The wind is about 45 knots blowing from the port (left) side of the ship.  The circle in the window is a small section of glass that is heated and can spin.  If spray starts to freeze on the windows this will keep a small spot open so you can look out.

This trip across the Drake Passage has been a bit more interesting than our last one.  On these graphs you can see we are moving between two stormy areas.  The dips in atmospheric pressure generally indicate bad weather.  The wind has also been strong, reaching more than 40 knots. On June 8th the wind sensor was frozen in sea spray and stopped working for a bit.  You can also see a big temperature increase when we turned left out of the Bransfield Strait to head northwest to South America across the Drake.  The water in the Bransfield is colder than the water offshore and it creates a boundary for weather patterns.
