Less weight of machinery and coal to be carried, resulting in greater speed.
Greater simplicity of machinery in construction and operation, causing less liability to accident and breakdown.
Smaller and more deeply immersed propellers, decreasing the tendency of the machinery to race in rough weather.
Lower centre of gravity of the machinery as a whole, and increased headroom above the machinery.
According to recent reports, decreased first cost of machinery.[39]
