Thomas Rainey, Ocean Steam Navigation and the Ocean Post
“ It is by no means essential that these small coasting vessels shall be propellers; for to acquire the same speed they expend the same power and have the disadvantage of being deeper in the water, and not being able to go into all harbors with much freight. They have also the advantage of carrying more sail, and being generally better able to stand coast storms than a side-wheel of light draught of water. They are not quite so expensive in prime construction, but generally require more repairs, and must be on the docks much oftener. ”
