Day 17 - The Astrolabe

Today was a nice day at sea!

We turned the clocks back an hour and we will continue to turn the clocks back as we continue around the globe!  So an extra hour of sleep will be great!  

Today I worked on watercoloring a favella - the slums of Rio.  It took a while to draw, then outline so I only started!  

There was a lecture on the most famous legends of the sea - King Neptune, Atlantis, the Odyssey, Robinson Crusoe - as well as incredible voyages - Shackleton's Endurance, HMS Bounty - as well as nautical superstitions - Flying Dutchmen, Bermuda Triangle and even maritime traditions - sideboys, crossing the equator!  

I learned more about the Clock Tower Planeto Asterolabium today.  The astrolabe is an ancient astronomical computer for solving problems relating to time and the position of the Sun and stars in the sky.  Older astrolabes were made of brass and were about 6inches in diameter. Astrolabes are used to show how the sky looks at a specific place at a given time. The clock tower in the Atrium of the ms Amsterdam was created by Lebigre & Roger in Pietrasante, Italy. The Astrolabium has a tellurium above the clocks which show the exact position of the moon in relation to the earth. On the top is a large dome with the Zodiac and the stars.  The first clock is connected to the carillon. The second clock shows the sky over the city of Amsterdam with the pole star in the center as reference. The third clock is a world clock that shows the time in different cities around the world.  The fourth clock is a planetarium which shows the motion of the planets in relation to each other.  There are ladies in each of the corners that represent the four seasons.



Tonight we have a meet and greet to get to know more people on our trip and dinner. Hopefully there will be chilled soup! Last night I had chilled sour cherry soup!

We will pass Punta Del Este tonight where we will begin our approach toward the Rio de la Plata.  These are narrow channels that are 115 nautical miles long.  When sailing in these channels the ship had to proceed at a reduced speed due to the effect of squat on the vessel.  As the ship moves through the water, some of the water is displaced and this causes an increase in the ships draught.  The faster the ship moves through the shallow water the greater the squat so that is why we travel slow.  

Buenos Aires tomorrow!!
