Crow languishes here in Port Newark.
A detail-impoverished foto of Manson Construction‘s hopper dredge Glenn Edwards along with tug Kendall J. Hebert. Actually Samantha Miller is hiding in the haze near starboard stern of the dredge, anchored in Gravesend Bay.
Click here for a coloful foto of Kendall J. Hebert.
Some of the other boats I’ve seen recently are Susan E. Witte,
Katherine, (Last summer I caught Katherine pulling a dredge scow in Morehead City, North Carolina)
Pati R. Moran,
Ron G, which I first read as Rong. Often she’s in Philadelphia.
Gabby L Miller,
Miriam Moran returning to base after retrieving the docking pilot,
And finally, a boat I’ve never seen before . . . Navigator. Anyone know her story? I took this foto Sunday morning.

Twenty thousand feet under the sea?
well . . . maybe just some marine equipment in a drydock.
Oh! This is Caddell’s Drydock #1, which you saw enter the harbor here just five months ago.
And this is Weeks Marine R. S. Weeks, with an unmistakeable ladder–the part that works while submerged. Click here to see what’s left exposed when the ladder is submerged and working.
Since this vessel is 32 years older than C. R. McCaskill, featured on this blog last week, it seems natural to compare them. Visually, design features differ. This dredge has quite different support structure (I know there must be a technical term (help?) . . . but I’ll try “derrick” to raise and lower the ladder and cutterhead. Ditto, the spud support structure on the stern differs. Click here for specifics, but it turns out that R. S. Weeks has a larger hull (268′ x 65′ x 17′ versus 230′ x 62′ x 14′) but cannot operate as deep as McCaskill. Also, Weeks was built on the Susquehanna in 1980 to serve as an “industrial vessel” for Adco. Not sure what that means.
Here are some closer-ups of the work.

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.
What’s this? Answer follows. And I just stumbled onto this blog . . . Crewboat Chronicles. Crew boat or crewboat?
OK . . . asking questions seems to be where this post wants to head. What’s Stagetide? The foto was taken on the hard not far north of Atlantic City and with the help of Fred Mallett.
Here are two crewboats I got a blurry foto of a few weeks ago in the KVK.
Crewboat Sabine plays lots of roles. Is she doing a visual inspection of dredge pipe here?
She also ferries crew and supplies between shore and projects, hydrographically surveys an area pre- and post-material removal, and shoos away non-project boats getting too close to the work. Sabine was built in New Iberia in 1980.
I’ve not been able to find out much about Stagetide.
Circling back to the top foto . . . it was the Swiftboat from the Washington Navy Yard, a vessel whose design alludes to its crewboat origins, I think. Here’s a post I did two years ago on swiftboats.

Related: The Bayonne Bridge logo I’ve used on this blog since 2006 was taken from the USACE vessel . . . Hocking. I believe that’s a crewboat, the first I ever rode in. Anyone know where Hocking was built?
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.

Welcome to the Inner Harbor of Syracuse. It used to be said that from the Inner Harbor, you could go anywhere in the world. Or anyone from “anywhere in the world” could get here. That’s a bit of an exaggeration; for example, you couldn’t get here, the Bonneville Salt Flats. But then again, someone making that claim about the Inner Harbor wouldn’t need to get to this mineral-rich Utah deposit. Explanation follows.
I ended up in the Inner Harbor in August because I wanted to see the shops
where the Erie Canal tenders had been built. And I’m still working on that. But in the process I stumbled upon
Erie Canal here is today Erie Boulevard. And the sign above relates the upstate NY location to the Utah western surface deposit.
Stop by the visitors center if you are nearby.

Actually the key is making it possible for the helicopter to find you. In some cases, assisting the task of arriving at your location makes the difference between life and death; things don’t always go so well. On a windy unsettled afternoon last week I happened to be there when
an obsessively circling C-130 over Oswego’s lighthouse demanded attention. I wish I’d stumbled onto this scene the day they trained search & rescue with a Reaper drone. Here’s another link about that drill.
As it was, the helicopter here working with the USCG puzzled me, and
having no VHF or binoculars, I couldn’t tell whether the debris on the jetty was just drifted remains of a Lake Ontario shoreline tree, but
someone had certainly swum to proximity of rescuer.
In the half hour that followed at least a half dozen “winchings up” and “down” before
it returned to USCG Station Oswego. Click here for their flickr page. Click here for info on the blue-yellow structure to the lower left, NYS Derrick Boat 8, the last steam-powered barge (with dredge capabilities at one time) on the Erie Canal . . . maybe even in New York . DB8 is also known as Lance Knapp, named for a salvage diver.
A half year ago I watched a helicopter rescue drill here.
All fotos taken within an hour by Will Van Dorp. Here was my previous swimming post.
PS: Enjoy the additional fotos below from the Port of Oswego, showing schooner OMF Ontario, LT-5, and fishtug Eleanor D, and Oswego West Pierhead Light.
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.

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.
