What do you think if we visit the captain and the mates up in the bridge today? After all, that is where the navigation takes place. Before we do so, close your eyes and imagine what the bridge might look like based on the books you have read and the movies you have watched; perhaps you have been in different boats and have a very good idea of what we are about to find.

    Based on my media-driven view of a bridge, I was a bit disappointed when I went to see the bridge for the first time. I was expecting the captain standing in front of a very large wheel while steering the ship. I knew there would be no parrot on his shoulder or a large shiny bronze funnel on his side through which he would yell to the engineers down in the engine room how fast he wanted the ship to go.

    Let us go up the five flight of stairs from the dry lab. Here we are; see? no large wheel, but the disappointment does not last. The bridge is a very large open space with tons of tables full of buttons, lights, computer screens and dials. It is surrounded by very large windows that provide us an almost 360° view of the ocean. It looks very cool!

    You might be tired after climbing all those stairs, but do not even think on seating on the captain's chair, that is big no, no. Take a look and enjoy the views. The circle you see on a couple of the windows are the 'clear view' windows. They are heated double pane glasses. The outside glass spins very fast, which drives all the water away, so the captain and mates can see out even in the worst storms. You might also be able to see that some windows have a square box on the upper left corner. These are also heated by very thin defrosting lines all through the glass like the defrosting lines on the back window of cars. The difference is that these lines embedded on the glass are so small that I had not seen them until today when a mate pointed them out, and I have been on the bridge looking through those very same windows countless hours.

    This is a view of a cold day through one of the clear windows towards the stern. You can tell this one is not heated because it is frosted, kind of like a bathroom window.

    The navigation is very automated these days. The mates prescribe the path and sped on the computer and the global positioning system (GPSA Global Positioning System (GPS) is a satellite-based navigation system used to track the location or position of objects on the Earth’s surface.) system makes sure we follow it at the right speed. The mates modify this path when icebergs appear ahead of us, but we come back to it as soon as we pass them. Here is Brandon, the second mate, at the controls.

    The navigation system also keeps the ship in the same position when we are in a station, although the mates occasionally override the setting to make sure the bow points towards the waves to avoid rolls. The Palmer has a thruster towards the bow that can be pointed to any direction and push with as much thrust as needed. Here as picture of the computer monitor that shows the thruster in action while at a station. The arrow pointing to the left shows the push of the thruster.

    It is good to see that the mates keep practicing their regular navigation skills in case the automatic system were to fail. Here is the desk at which they map with paper and pencil our location like in the old days.

    I was told the same thing than in our visit to the engine room (April 5), this equipment was top of the line 20 years ago, but now it is dated.

    There is a lot of important equipment, and I had the privilege of being shown the most important piece of equipment on the bridge. The mates seem to not be able to navigate without this simple, yet indispensable, tool.

    Hope you enjoyed visiting the bridge. This is the place to be when you want to enjoy the views being warm and comfortable. The mates appreciate the company, so drop in when you can.

    El puente de mando

    ¿Qué te parece si visitamos hoy al capitán y los mates en el puente de mando el día de hoy? Después de todo, allí es donde se lleva al cabo la navegación. Cierra tus ojos antes de subir, e imagínate como es el puente de mandos con base en los libros que has leído y las películas que has visto; quizá tienes experiencia en barcos lo que te da una buena idea de lo que estamos a punto de encontrar.

    Gracias a mis experiencias cinéfilas y literarias, me desilusionó un poco ver el puente por primera vez. Esperaba encontrar al capitán parado frente a una gran rueda a modo de volante para dirigir la embarcación. Sabía que no le vería con un loro al hombro ni con un embudo brillante de bronce por el que gritara a los ingenieros la velocidad a la que quería que se fuera.

    Subamos los cinco pisos de escaleras que nos conducen desde el laboratorio seco hasta el puente de mandos. ¿Vees? no hay volante que ver, pero la desilusión dura poco ante la vista de tan amplio espacio y las mesas llenas de botones, lucecitas, monitores de comutadora y medidores. Esta rodeado de enormes ventanales que nos brindan una vista de casi 360° del océano. !Una vista genial!

    Quizá te cansaste al subir tantas escaleras, pero que no se te ocurra sentarte en la silla del capitán. Disfruta las vistas. Los círculos que ves en dos de los ventanales son las ventanas de 'vista clara'. Tienen dos vidrios que se calientan con una resistencia eléctrica. El círculo de vidrio exterior gira a gran velocidad, lo que hace que se vaya el agua de su superficie. Quizá puedas ver unas cajas cuadradas en la parte superior izquierda de algunos ventanales. Estos también se calientan con una pequeñas líneas que van dentro del cristal como las de las ventanas posteriores de los autos. La diferencia es que éstas son muy, muy pequeñas. Tan pequeñas que apenas las vi hoy cuando Brandon, el segundo mate, me las enseñó, eso que me he pasado largas horas viendo por esas ventanas.

    Esta es la vista atraves de una de de las ventanas que dan hacia la popa. Se ve que esta no se calienta, ya que esta cubierta de hielo. Parece una ventana de baño.

    La navegación es muy automática estos días. Los mates prescriben la trayectoria y rapidez a seguir en la computadora y el sistema posicionador global (GPS, por sus siglas en inglés) se encarga de seguir las instrucciones. Los mates cambian rumbo cuando aparecen icebergs en nuestro camino, pero retomamos rumbo enseguida. Aquí está Brandon, el segundo mate, en los controles.

    El sistema de navegación también mantiene al buque en posición fija cuando estamos en una estación, aunque los mates también cambian las instrucciones para evitar el bamboleo del barco. El Palmer tiene una propela cerca de la proa que se puede dirigir en cualquier dirección y se puede cambiar la propulsión. Esta propela sirve ara mantener la posición del barco. En esta foto se ve la pantalla de un monitor en la que se indica con una flecha la dirección y magnitud de la fuerza de la propela de proa.

    Es bueno ver que los navegantes siguen practicando sus habilidades de navegación en caso de algún fallo en el sistema electrónico. Aquí el escritorio en el que trazan nuestra trayectoria, como en los viejos tiempos.

    Me dijeron lo mismo que escuché en nuestra visita al cuarto de máquinas: este equipo fue el mejor hace 20 años, pero ahora es un poco anticuado.

    Hay mucho equipo importante, pero al final tuve el privilegio de ver el más importante de todos. Al parecer los mates no son capaces de navegar sin esta importante herramienta.

    Con esto terminamos nuestra visita al puente de mando. Este es el lugar ideal para disfrutar las vistas sin enfriarse y con mucho confort. Los navegantes agradecen la visita, así que visítalos de nuevo cuando puedas.
