The use of certain technologies is rarely a stand alone decision. The switch from sail to steam did not happen overnight and they actually coexisted for over a century, where, based on available technologies, in certain applications steam was more attractive and in other applications sail was more attractive.The eventual dominance of screw propellers over paddle wheels was not even driven by technological considerations, but rather by a tug of war between a paddlewheel propelled vessel and a screw propelled vessel.
