Here was the first post . . .LNYB . . being Lower New York Bay. I’m wondering, though, if this might technically be the corner of New York Bight, not the Lower Bay. The “sixth boro” nomenclature . . . blurs the distinction.
The Rockaway Lateral pipeline project is . . . partly about pipe. How the pipe gets “injected” into the earth is illustrated in this video. Bear with the first 45 seconds . . . the remaining 4 and a half minutes are illuminating.
Thanks to a secret salt for these photos of taking on pipe and provisions.
Here are fleet mates.
All above photos from a secret salt. If I’m not way off, the photo below–not so close up–shows Michael Lawrence alongside the “pipe-injector” barge.
This last photo I took on Tuesday.
Well, clearly I’m not the only one who recognizes how delightful Alice’s presence in the sixth boro proves to be.
Thanks to the Long Island City Community Boathouse for these pics long on spirit if perhaps a bit short on focus. My last trip with LIC Community Boathouse goes back five years already!! On that Sobro cleanup trip I also took these fotos.
These fotos remind me that I’ve yet to get myself to Four Freedoms Park (below) on Roosevelt Island, as well as

Aug 31. A late summer day at the beach, where a new “towel drying rack” has been adopted and a bumper crop
of sand awaits the erosion of winter, perhaps? All photos here taken by Barbara Barnard.
Sept 1. A tug (Trevor?) moves a crane barge to where the “drying rack”/piping needs to be fished out for transport to the next job.
Sept 13. The remaining pipe on the beach, no longer serving to dry swimmers’ towels, awaits dismantling and
allows for closer inspection.
This Rockaway series was of course motivated by Hurricane Sandy and the photos of Rockaway by my friend Barbara in the past 12 months. Barbara, many thanks. Here was my Nemo to Flag Day post, which started with a mystery house.
Click here for a project/business entirely created by the devastation of trees during the storm. It’s not maritime, water, or even specifically landthreshold related, but is quite interesting.
Here’s where the “leverman” sits for a twelve-hour shift as the C. R. McCaskill slews port to starboard 400′ once each three and a half minutes. Another way of saying that is the dredge moves using a five-point mooring system: two swing anchors, two breast anchors and one stern anchor to move forward or back. A different configuration uses a spudded idler barge; in this case, the “swing” is longer and takes more more time. Food gets delivered so that the leverman aka dredge operator can monitor all these screens and respond so that dredging can proceed 24/7 as long as equipment and conditions permit. More on food later.
Slewing . . . drawing on cables attached to positioned anchors and pivoting on a stern point . . . requires that the 30” diamater hose be able to flex. Hence, the easy curved slack before the piping to the beach.
The crewboat in the distance alternates between hydrographic survey work and other tasks. More on that in a moment. More crewboats in a future post.
Attachment at the stern is a ball and socket joint . . . like your hip.
Here’s the starboard GE engine, part of the power supply to the dredge.
Here is another view of the two huge hull-mounted pumps that do the work.
Another task of the crewboat is illustrated here: recreational boaters sometimes allow their curiosity to override any sense of danger caused by a busy, slewing dredge.
The helicopter happened to be here on assignment to photograph the work from the air.
About the food, here’s mission control presided over by Edwina Arthur, a member of the 30-50 person crew.
Food rules and pecking order are clearly posted.
Captain Randy Guidry, my host for this tour, proudly displays the builder’s plate, Corn Island Shipyard in Indiana, where the hull was constructed.
As I stated in the previous post, McCaskill’s part in the dredging/beach replenishment has now ended and vessels and crew have moved south for the next job.
Many thanks to Captain Guidry, Jan Andrusky, and all the other fine folks at Weeks Marine for this tour.

Here and here are previous posts on a Rockaway Beach replenishment dredging operation that has now ended. Sea Wolf is still local, but the vessel on the horizon (“atop” the red buoy) has now moved to southern NJ. Remember, for most fotos, doubleclick enlarges.
Weeks’ Trevor was assisting in this project.
Also assisting was George W.
But here’s the powerhouse, the dredge. Let’s take a tour.
In spite of about 16,000 total horsepower, C. R. McCaskill is not self-propelled. To see what towed the dredge to the south, see the foto at the end of this post. All that power moves the cutterhead on the submerged arm (called a “ladder”) that extends to the sand at the bottom of the Channel here. At the top end of the ladder are two huge pumps (you could stand inside the pump housing) that suck the sand and whatever else off the bottom and send it as a slurry to a point on the beach some miles away. Click here for a pdf that shows the beautiful (ok . . . roll your eyes) virgin red cutterhead with green teeth. Each tooth weighs around 35 pounds!
Here inside the dredge are some
interesting astounding facts about the machine.
See the sand colored building on the horizon off the stern of McCaskill? That’s the area around 105th St. Rockaway Beach where the sand is headed through piping powered by this vessel. The first few fotos in this post were taken at that beach. There’ll be another Rockaway post soon.
Candace towed C. R. McCaskill south. I missed her when she was in town, but John Skelson caught her here. Click on the foto to see John’s complete shot. Many thanks to John for use of that shot from his Flickr page.
All fotos by Will Van Dorp, except for the one shared by John Skelson. For more info on each of the Weeks tugs, click here. More McCaskill tomorrow.
This was the fountain this morning.
Once the slurry exits the mouth, water flows back into the ocean and sand is pushed up the beach.
This repurposed container is project headquarters.
The top foto comes thanks to Barbara Barnard; all others by Will Van Dorp.
I’m back, with lots of gallivanting to catch up, but first . . a whole lotta fotos from this morning in the sixth boro. Any ideas what’s going on here? What is that gray blur in the center of the foto and why are the gulls so frenzied? Be forewarned . . . this post has so many twists/turns . . . it’s divided into parts, even though I took all these fotos in the span of less than an hour.
Answer: It’s how over three million cubic yards of sand is being added to Rockaway Beach . . at least for a while. Here’s what the NY Daily News says about it. Here’s an article and video from Dredging Today.
And here . . . off in the Rockaway Inlet are the machines mining and pumping the sand, seen closer up in this recent tugster post.
Part 2. Notice the piping coming from the stern of McCaskill.
I could not resist wondering about these birds whose name rhymes with “lovers.”
Part 3. Follow this sweep of fotos as I turn to the left.
An Atlantic City billboard on Far Rockaway? Is a mixed up sense of geography part of Sandy’s legacy? I keep turning left.
See the silvery cars of the A train? It’s a Boardwalk Empire set in the wasteland of eastern Rockaway Beach . . . . I was hoping to buy some of that food at those prices!
Of course, I had to look behind.
I half expected to find some Aral Sea boats back here too.
Part 4. Once back on the boardwalk, I saw this fishing boat about a quarter mile from shore. I’m guessing it’s unrelated to the sand piping and pumping, but . . . who knows.
All fotos today by Will Van Dorp.
A half century ago, that lake was the site of the World’s Fair. And the three images that follow are stills clipped from a short video called Sinclair (as in the oil company today subsumed by Arco) at the World’s Fair, which today we might call an infomercial. Thanks to all your comments–here and via email–that lead me to conclude that the hydrofoil era in the sixth boro was quite short. Looking at these fotos, I wonder if any reader here was among the 100,000 passengers transported in the summer of 1964, if any fotos out there could be shared, and
what this “driver” did after hulls receded back into the water for good. Thirteen boats–maybe unfortunately named–operated in the sixth boro! Where did they dock? Who maintained them?
Here’s an intriguing eBay foto, which I’ll not bid on. Boeing seems to have built a number of hydrofoils–as the Boeing 929. Of those still operating, most are in Eastern Asia, including these “Seven Islands” boats that once–about a decade ago–tried to establish a run between Florida and the Bahamas. Seven Islands features an up-to-date crew blog–only in Japanese–that has interesting fotos. Here and here is info on a hydrofoil operating on the black Sea out of Bulgaria.
Here’s where I’ll leave this until I find out more.
Meanwhile, if I get all my work done today, I may go see the dragons tomorrow.
So what travels through this piping?
For more technical info on McCaskill‘s capabilities, read this article by my friend Brian Gauvin and published in the August 2013 issue of Professional Mariner magazine. In the article, he talks about McCaskill‘s ability to send dredge spoils six miles through a pipe to restore and create marshes to serve as hurrican barriers in Louisiana.
So although I haven’t seen it happen yet, I’m concluding that this vessel can pump whatever comes from the East Rockaway Inlet to the location three or so miles to the west, where you saw Trevor, George W, and Sea Wolf operating in yesterday’s post.
Three years ago I took fotos on another cutterhead suction dredge– one that’s a half century old–operating in the KVK back in 2010. Click here for some of those fotos, including one that shows the size of the pump used to move dredge spoils from point of “collection” to point of “use.”
All fotos by Will Van Dorp, who most recently saw a Weeks tug at work in a dredging project in a North Carolina Inlet. My question is . . . does anyone have fotos to share of C. R. McCaskill‘s transit from its inaugural work in Louisiana to its current location in the sixth boro?
And Sabine . . . looks like she was launched back in 1980 from here.
Thisjust in . . . the Daily News story on this post-Sandy project, as seen from a politicophile POV.
there’s a tube in the water, there must
be a shear leg or
two lurking nearby, although I wonder if these are shear legs . . . technically speaking.
I’m not positive what Sea Wolf
George W, and
and Trevor were doing . . . other than arranging the dredge spoils pipe,
with Sabine monitoring . . .
ut it has to do with the mother dredger ship some distance away. Fotos of her . . tomorrow. And if there’s a dredger’s rainbow and someone gets a pic, I’d love to see it.
