I finally figured out why my cutterhead kept clogging in that sandy soil near Mobile Bay
Ran a job outside Mobile, Alabama last month where the sand was so fine it just packed right into the cutterhead teeth. Three years of doing this and I never dealt with that. Turns out running a higher water speed on the jet pump was the fix, not lower like I thought. Anybody else run into weird sediment behavior depending on the exact spot you're dredging?

The trick with the jet pump makes sense - that fine sand basically turns into a slurry that needs more momentum to keep moving. Actual soil density in Mobile Bay can vary a crazy amount too, even just a few feet apart, from what I've heard from locals. Almost wonder if your cutterhead profile itself is trapping it more than you'd expect.
