Ships that are propelled magnetically by ionizing sea-water between two electrodes in a magnetic field have been built.

However building a ship with a spiral helix barrel within what the sea-water is ionized and accelerated could contain the electric currents mostly to within the barrel.

When the magnetic field is applied to the electrically polarized sea-water it would spin the spiral helix turbine providing thrust of considerable magnitude because it's would give it a fly-wheel effect that not only would push water but draw it in from the front.

The volume of water within the barrel of the spiral helix turbine would be immense and the angular momentum of the sea-water low could be focused/harnessed to enhance the speed of the Ocean-liner/Naval-ship.

The outlet nozzle could be swiveled to permit/enable fast turning circles and powerful acceleration that isn't restricted by the so-called `forward speed of the propeller'.

Is it this you are speaking about

Other than the link posted above, your design seems to also be used to turn a spiral helix turbine. You mentioned using the water as thrust to propel the vessel. So what does the turbine do? ,, other than slow down the water and reduce it's thrust.

Yes, the Spiral Helix is most suited to Turbine Power Generation, with marine propulsion it would also be revolving a heavy mass of water. At the time I was thinking of the inverse of a power generator and that would be a motor.

Pushing against a heavy mass of of revolving water wouldn't give it much speed but perhaps power in pushing through arctic sheets of ice
