paddle wheel

The 'Syria' was originally a paddle-wheel steamer, having oscillating cylinders worked with steam of 25 lbs.

In the same vessel he adopted a feathering paddle-wheel and the guard-beam now universally seen in our river steamboats.

The screw was found to possess many advantages over the paddle-wheel as an instrument for ship-propulsion.

All these were paddle-wheel boats, and paddle-wheel boats are not adapted to work in heavy seas.

With chain or rope traction there is no loss by slip or oblique action, as in both screw and paddle-wheel propulsion.
