The five-minute video at the end provides the sound: violent and jarring. But first, try to conjure up what you think you’ll hear from the following images. Remember, double-click to enlarge x 3 an image.
Air temperature at the Rondout this morning registered a scant seven degrees at daybreak. Morro Bay, heading north on the Hudson about a half mile away, seemed like a phantom.
Cornell had an icebreaking assignment; any strands of its pudding frozen into the ice will be plucked as the tugboat breaks free after a mere two frigid days on the dock.
Ice thickness was more than half a foot. According to this site, 3-inch ice can support a person and 10-inch, a car. Of course, there are other variables.
In seven-degree air temperature, freshwater ice refreezes minutes after being broken.
After heading up to Feeney Shipyard breaking one swath, we headed back to break another, all the way out to where Rondout Light marks the mouth of the Creek.
Out in the Hudson, Dann Marine Towing’s Zeus pushes a cement barge northward, following the track opened by Morro Bay,
a track which a short time later seems lost, dissipated like a boat wake in summertime or a trail in a windy desert.
Now brace yourself with the sound of water cracking.
Compare the sound of the Rondout with that of Bowsprite’s Raritan.
And here’s Harold’s video of Hudson River traffic as seen from the Poughkeepsie walkway.

Happy New Year Will. Nice Icebreaking coverage from the CORNELL both photos, and video. I was down on the southern part of the river on Sunday taking ice photos at Newburgh, West Point, Storm King Overlook, Plum Point, and finally after a tip off from Jeff; I made it up to the Walkway to catch video of the Taurus and DBL 27. Thanks for posting my Kimberly Poling video over here. You are also more than welcome to post the coverage of the Taurus if you like. STURGEON BAY is upriver this week, and I talked with Scott Rae about coming aboard. I will get some more live coverage over there throughout the ice season, and Sunday I spoke with the CO on the MORRO BAY who extended his invitation for me to spend some time aboard. I didn’t know if you were aware, but the PENOBSCOT BAY left Bayonne before the holidays, and is deployed for the winter up on the Great Lakes. Looks like the lineup for the Hudson this winter will be STURGEON BAY, MORRO BAY, LINE, WIRE, & WILLOW.

What a fabulous posting, Will. A couple questions: When they break fresh ice, do the shards, I assume, all just go to the side? On top of the unbroken ice? Underneath? Second, I seem to remember that the big Russian ice-breakers on the Arctic Ocean would almost ride up on the ice and use their weight to break it downward. Is that only when doing it at such a scale?

some ice-breaking insights: fresh ice broken seems to go helterskelter. once broken, the ice freezes tougher according to matt; hence, second time through is even more jarring. russian icebreaker dealing with thicker ice as well as the uscg 140′ icebreakers have hulls designed to attack the ice as you describe, almost manual can-opener like. matt’s heavy rail tug just powers through. think of icebreaking as cutting with a knife: knives have specialty designs such that (eg.) a cleaver is used differently than a serrated blade. so it is with hulls used for icebreaking.

Well, I thought I could hear the difference. The second-time-frozen ice did make much more noise in the breaking, while I thought the fresh-frozen ice would be louder. But of course. A scar is tougher than fresh skin.
Did Matt say the thickest ice he’s ever brought his tug through?

daniel- here’s matt on ice breaking and cornell hull thickness: “As for hull thickness… Cornell was built with a 3/4″ bow, 1/2″ sides and 5/8″ bottom plate. The modern 140′ class CG breakers (like Morro Bay and Sturgeon Bay) are typically 3/4″ throughout the entire hull. This allows them to break ice at 10kts or better where I am limited to 5kts in anything over 6″ thick. But I can make it through 10″ ice at 2.5kts all day in the creeks where the big CG boat will not go.”

Wow, how cool. 10″ ice. Take your time breaking it at 2.5 knots, the scenery is so lovely and the air is fresh and clean. God bless the old Cornell. Perfect name for a Rondout boat. The Cornells were one of the Huguenot families that settled the New Paltz and Wallkill area. (New Paltz, from the Rhine Palatinate, where they had lived for one generation in between France and New York. Wallkill, from Waalsekill, because the Dutch Calvinists called every Protestant Frenchman a Walloon.)

dan- you are a blessed font of info. i didn’t put together the waal and kill as origin for this place name. we should take a trip upstate again and admire the ice and whatever else we encounter.

thank you for writing, lazerone. i will find more icebreaking!
