Travel Theme: Work

By Vladimir Brezina

Ailsa’s travel-themed photo challenge this week is Work.

Work is done upon an object when a force displaces it through a distance—

Work

—and nowadays, when everything works as it should, gigantic amounts of work continue to be done even when the workers take, for a few moments at least, a break from work—

New Bridge Over the Hudson

By Johna Till Johnson

As many of our readers know, I’m a huge fan of bridges. To me, they’re beautiful both physically and metaphorically—lovely structures that bring two sides together. Although my favorite bridge is the Hell Gate Bridge, I’m passionate about all the New York waterway bridges.

So it’s a big deal to me that New York will be replacing the Tappan Zee Bridge—and the new structure will be complete relatively soon (supposedly, by 2018).

Here’s what the Tappan Zee Bridge looks like today:

And here’s what it’s supposed to look like in future:

I’m not crazy about the outward-reaching “harp” towers… but it is a bridge, and I love bridges… What do you think?

Ceres

By Vladimir Brezina

A week ago, over the Columbus Day weekend, we were kayak-camping at Stockport Middle Ground, one of my favorite places along the Hudson River, to paddle among the Fall colors (story and photos forthcoming!).

So on Monday a week ago, I paddled out onto the still river, shrouded in fog, as the first colors of dawn softened the sky. Honking geese flew overhead.

But what was that strange buzzing sound, and that strange object emerging from the fog upriver, gradually growing bigger?

Book Review: From Pigeons to Tweets

By Johna Till Johnson

From Pigeons to TweetsFrom Pigeons to Tweets: A General Who Led Dramatic Changes in Military Communications, by Clarence E. McKnight and Hank H. Cox. History Publishing Company, Palisades, New York, 2013.

Okay, I know I have weird tastes in reading material. But when I picked up “From Pigeons to Tweets”, I didn’t expect what I actually got.

The subtitle is “A General Who Led Dramatic Changes in Military Communications”, and the author is Lt. Gen. Clarence E. McKnight Jr. (along with journalist Hank H. Cox).

Given that, plus the relatively staid promotional blurbs from a range of military luminaries, I was expecting a dry treatise on the history of military communications technology.

That would have been interesting enough. I’m fascinated by military technology in general, and military communications technology in particular. (I told you I have weird tastes!)

What I got was (in part) a rollicking and thoroughly absorbing memoir by a man who rose to the highest ranks of the U.S. Army’s Signal Corps (the branch that focuses on communications technology) and who had a reputation for hands-on effectiveness in setting up communications systems. (“McKnight could communicate from Hell,” says one of his colleagues—as a compliment.)

How Many Bridges Circumnavigating Manhattan?

By Vladimir Brezina

Some of the Manhattan bridgesIt’s interesting to look occasionally through the search terms that people have entered to reach your blog. And recently, quite a few people have been arriving at Wind Against Current with the query “how many bridges circumnavigating Manhattan”. They’ll have been disappointed in not finding an answer—until now!

Another popular query is “how many islands in New York City”. Unfortunately, that question does not have a definite answer—it depends on what you consider an island, and on the state of the tide.

But “how many bridges circumnavigating Manhattan” does have a very definite answer. And the answer is…

Hidden Harbor Tour

By Vladimir Brezina

DSC_0729 cropped smallOnce in a while it occurs to us that there might be other ways to see New York Harbor than by kayak.

And so, on Tuesday evening, we traveled down to the South Street Seaport and boarded the yacht Zephyr, for one of the Hidden Harbor Tours organized by the  Working Harbor Committee. Our appetites had been whetted by the recent Tugboat Races, also organized by the Committee. And reading the description of this tour, it promised to be another highlight:

This tour passes by the Red Hook Container Terminal and visits Erie Basin, home of Hughes Brothers Barges and Reinauer Tugs before crossing the harbor toward Staten Island. It then enters Kill Van Kull, the area’s busiest waterway dividing Staten Island and Bayonne, passing tug yards, oil docks and marine repair facilities. It then passes under the Bayonne Bridge and visits the giant container ports of Newark Bay, Port Newark and Port Elizabeth where the world’s largest container ships tie up. On the way back, we pass by Military Ocean Terminal, the 9/11 Teardrop Memorial, the Robbins Reef Lighthouse and another container port, ending up at the Statue of Liberty for a moment before returning to Pier 16.

We got all of that and more.

Travel Theme: Hidden

By Vladimir Brezina

Ailsa’s travel-themed photo challenge this week is Hidden.

In our kayaks, we can poke into the most obscure corners of New York Harbor. And we do! And over the years, we’ve found there many fascinating hidden things.

SchamonchiMany of them are remnants of the maritime and commercial history of the harbor. There are substantial ships tucked away at the ends of narrow waterways, acres of wrecks,

The Yellow Submarine

even a submarine…

Here is another strange, intriguing structure. It’s located a little out of the way, in Port Reading, NJ, on the Arthur Kill behind Staten Island. It’s not exactly hidden—as you paddle up the Kill you can see it in plain sight from a long way off. But you have to notice it particularly, as it blends rather well into the general decayed industrial look of the shoreline. And, on the first visit, the pink wreck of the Major General William H. Hart just in front of it (in the first photo below) completely steals the show.

So, although we’ve paddled past many times, we’ve only once taken a few minutes for a closer look. This was in September 2010, when these photos were taken (since then, the structure has reportedly deteriorated even more).

At that time, we didn’t really know what we were looking at. Now that we do, we must go back for a careful inspection!

So, what is it?

It’s a McMyler Coal Unloader. Built in 1917 and operating until the 1970s—according to some accounts, until 1983—it’s the last remaining one of its kind in the New York area. Originally there were at least eight of them along the shoreline of New York Harbor, each operated by one of the railroads that brought coal in from Pennsylvania and the Alleghenies. One, described in loving detail here in a 1951 article, apparently was located on Jersey City’s Pier 18, a now completely vanished 900-foot quay extending into the Hudson River between Liberty and Ellis Islands!

In operation, an open-topped railroad car full of coal was pushed into position inside the unloader’s tower. It was then grasped by the machinery, bodily lifted up, and turned upside down so that the coal spilled down a chute into a waiting barge (moored about where the tug Turecamo Girls is moored in the photos above). The empty car was put back onto the rails and given a little shove, so that, like on a roller coaster, it rolled away by gravity down an incline while the next full car was pushed into position…

The Garden State Central Model Railroad Club has built a working model of a McMyler Coal Unloader, seen in action here:

No dainty opening of little hopper doors here. This was a crude, brute-force approach that worked. The McMyler Coal Unloader could empty a 100-ton car every minute or so, continuously. A fascinating relic of the heroic industrial age—it might have been built by giants!

Tugboat Races 2013

Last year, on the spur of the moment, we attended our first-ever Great North River Tugboat Race & Competition (see the writeup, “We’re Off to the (Tugboat) Races!”).

We were stunned, blown away, and delighted by the experience.

So it’s only natural that this year, we were conflicted. On the one hand, we were eager to go again; on the other hand, how could it possibly live up to the previous time?

Let’s just say… it did.

… Labor Day, and (practically speaking) the beginning of Fall!

Here are a few celebratory photos taken at yesterday’s Great North River Tugboat Race & Competition. Lots more photos to come. (Last year’s are here.)

The Cardboard Kayak Race

By Johna Till Johnson 

Every now and then something comes along that’s just a sheer delight from start to finish.

Yesterday, it was this video of the 2013 City of Water Day’s First Annual Cardboard Kayak Race.  It features practically all of my favorite things: kayaking, engineering, competition (the thrill of victory and the cold splash of defeat), creativity, ingenuity, and whimsy. All on a beautiful summer’s day in New York!

The event was hosted by the Metropolitan Water Alliance, a not-for-profit that, in its own words, “works to transform the New York and New Jersey Harbor and Waterways to make them cleaner and more accessible, a vibrant place to play, learn and work with great parks, great jobs and great transportation for all.”

The Cardboard Kayak Race is exactly what it sounds like: Teams of competitors are each given identical materials from which they construct, and then race, cardboard kayaks. Starting materials include:

  • 10 5×5 squares of cardboard
  • 10 rolls of packing tape
  • 3 rolls of gaffer tape, and
  • a box knife

The video is long (though well worth watching—it will leave you laughing with joy!). But  if you’re pressed for time, here are some highlights:

  • The first 12 minutes feature various shots of boat construction
  • At 12:00, judging commences. You’ll meet the teams, which include the Brooklyn Bridge Park Boathouse, the NYC Watertrail Village Community Boathouse, the High School of Math, Science, and Engineering Alumni, El Centro (from Staten Island), the North Brooklyn Boathouse, the Stevens Institute of Technology, the Stuyvesant High School Village Community Boathouse, and the US Coast Guard Marine Inspectors.
  • There’s a great comment at 17:30 where the judge asks the Coast Guard team, “Which do you think is the front part of the boat?”, then adds, “I don’t want to confuse you with technical questions!”
  • The race begins at 18:18
  • There’s a nail-biter of a finish at 19:15
  • Disastrous and heartbreaking collision at 19:50
  • Dramatic capsize at 20:46

It’s all wonderful fun, and well worth the watch!
