We're sitting on the hook watching a movie and waiting to time our arrival at Ready Point.

Enjoy the movie. We are in Bellhaven, headed north ( I know the wrong way) Maybe we will pass in the Chesapeake.

We just had our DF 44 hauled for the winter at Delaware City. FWIW, there was a big dredge operating just off Reedy Point when we entered Delaware Bay from the C&D. Travel safe.

Thanks for the heads up. I wish I had read that earlier. My son had the helm (not paying attention) and I had just come up from my rest and I look up and a hundred feet in front of us is the dredge and three tugs!!! I grabbed the wheel and went hard to starboard. I then saw the pipes were on that side reaching out thousands of feet. Full about and came around leaving the whole mess to starboard. Five seconds was the difference. All this at 2:00am no moon light!

Wow!!! Glad you missed the dredge. It's a monster, alright. Getting around it in broad daylight was nerve-wracking enough. It was positioned at the junction of 3 busy channels when we passed it, which adds complications. The guy who runs the supply boat for the dredge is based at Delaware City Marina and actually operated the hoist that hauled our boat last week. He told me they have a vast amount of equipment in the water.

Nah...waiting for my release date when striped bass season winds down in early Dec. Probably leave for FL around 10 Dec, heading up the bay on the first light wind day that comes along.

Congratulations on missing those pipes! Contact not good!

I'm completely ignorant how they work - guessing now - the pump boat runs the pump and they just keep repositioning the pipes? We have the dredge Brunswick working here in the upper Cape Fear River and I have been watching with much interest. Do you know if with suction they have to maintain a certain soil/water mix?

I see the pipes going out hundreds of feet here, not thousands, but is interesting to watch. Curious how they manage the drop of the spoil (I keep looking for it), but I suppose with the pipes run it to a safe location.

I really suppose the captain wouldn't want some curious geek-engineering-type to quiz him over the VHF. Better Google this one.

That dredge is huge! Very confusing to see in the night.

Usually there's a tug moving the dredge around since most aren't self propelled. The pipe just follows.

Ok, so answering my own question here... Video linked animation is pretty explanatory.

I couldn't get the link to work, so I Googled it and got this. Hopefully, it's the same thing.

VMI, Inc. - How Dredges Work

Just as a matter of scale, the dredges in these videos would probably fit in the wheelhouse of the vessel moving the Delaware Bay dredge.

Ben-the link Angus posted is pretty much how dredges work. In years past when I lived down in your area (in Shallotte), I has several friends who worked dredges up and down the coast. As you go up and down the Cape Fear, most if not all the little islands you pass were created by dredge spoil. They used to maintain the Cape Fear channel at 38' deep, may be deeper now. It requires pretty regular dredging to maintain the channel depth. The dredges just suck it up and spit it out off to the side and make little islands all up and down the river. They also use the dredges in beach renourishment, sucking up sand from just offshore and pumping it to the beach to rebuild the beach. That is pretty much a wasted exercise as two winters of nor'easters and the beach is gone again!

Keep to the green lit side of the dredge (2 greens stacked). When in doubt call the dredge or tender tugs on ch 13

I have been observing one working downtown Wilmington - I can't see where the spoil is being laid, but I expect in the shallows. He's working the area which is indicated as a turning basin on the charts just south of the northern bridge and Bennett Brothers. Because of a tight channel, city proximity, and wetlands, I can only imagine the legal protection, insurance, and permitting must be extensive.

Honestly I never had occasion to think about it except that the dredge is now working right off the town bulkhead.

I'm done with this topic, having "drifted" from the subject of the thread.
