Across the Atlantic

We left Philadelphia on the afternoon of 3 March after a day's delay due to the storm. The trip down the Delaware River in the evening was uneventful and we had a nice sunset to see us on our way.

Overall the passage was relatively smooth. Like our earlier Pacific crossing we were able to keep between the harsher weather systems and enjoy comparatively pleasant weather. On our second full day at sea I was on the Bridge and the Captain pointed out the mists passing over the water. It looked like the steam one would see rising on a lake in the early morning. This was due, he informed me, to the convergence of the Gulf Stream with the Labrador Current. It dissipated after a short time as we made our way further eastward.

The ship has been rolling a good deal more than previously due to the ocean swells to our stern and this has been a cause for some minor discomfort among passengers and crew alike. It is a long, slow motion from side to side with a maximum deflection of about ten degrees from the vertical. A few people have difficulty sleeping and that, I think, is somewhat due to where their bunks are located; in my case I'm closer to the middle of the ship so I don't notice the roll as much, but those on the outermost cabins have to deal with a more pronounced movement. At lunch it sometimes requires a bit of caution when eating the soup as it tends to spill over the side of the bowl if one has too much. The actual motion sickness is another inconvenience but so far no one seems to be too adversely affected. I think the biggest problem is when one is inside a cabin or a hallway without any view to the horizon and the motion that one senses doesn't correlate to what one sees. Actually, it feels a lot like when one tries to walk after a little too much to drink and finds that one's feet do not cooperate as readily as one expects. Suffice to say it's a prudent measure to make good use of the handrails in the stairway and the grab-rails along the corridors.

In addition to being uncomfortable for the residents on a ship, severe rolling presents risks to the cargo and the ship itself, so the Captain ordered that we make a modified transit towards the English Channel. His colorful description was that we would take a course like "a pissing ox." Unbeknownst to me, oxen apparently don't halt in their travels when they need to urinate and the back and forth movement of the associated extremities creates a zigzag pattern in their wake as they walk along. We would follow a similar zigzag pattern to counteract the swell, turning a few degrees to the side of our course and then back again after a few miles, sticking basically to the course but making the necessary deviations to avoid the worst of the swell. The net effect is one of less severe rolling, at least shorter periods of it interspersed with brief intervals of comparatively smooth sailing. Naturally this will add some distance to our route, but not too much as the deflections are minor, only a few degrees from the most direct course. For the officers on watch they need to spend more time actively navigating and making the necessary corrections in order to find the best heading.

We advanced our clocks almost every other day on the passage as we had to make up five hours between Philly and Antwerp so I found myself feeling the effects of this "boat lag" as we approached the English Channel. I think this was mainly due to the set meal times, especially breakfast, where I had to make a bit of effort to go downstairs when I would have preferred another hour or so of sleep and didn't feel quite right until after a few cups of coffee.

One highlight for me during the passage was a tour of one of the heavy lift cranes. During a period of more moderate rolling the Chief Engineer very kindly gave me a tour of the inner workings, and letting me climb up to the operator's cabin. The interior of the crane tower itself is very impressive from the massive turret gear and 76mm diameter heavy-lift cable to the computer controls and hydraulic systems. The climb up and down the ladders was not too bad although some of the openings were rather cramped; there's not a lot of wasted space.

Ship traffic in the English Channel was very busy as we passed through. The watch officers and their lookouts were constantly keeping an eye on surrounding vessels, both visually and on their radar monitors. It's during these times that the officers really earn their pay. The 2nd Officer showed me how he used a simple line of bearing to a ship approaching from our beam to quickly determine whether it would pass in across our bow or our stern, or if we were on a collision course. It's a much more interesting way to learn geometry than anything I remember from my school days.

It was during our passage up the Channel that we crossed the Prime Meridian at 0 degrees longitude and returned to the eastern hemisphere. I was up at the forecastle with my GPS unit and was able to get a lucky shot of the screen just as we passed 00 deg, 00 min, 00.0 sec.



Finally, we were treated to a brilliant full moon for our evening passage. I tried to take some photos but couldn't really do the image justice.
