Tall funnels help draft boilers of smoke and gas from combustion and keep the particulate farther away from the vessel itself. Forced draft boilers eventually made funnel height less of an issue. Comparison to the Pargny is apples to oranges since for over a third of its commercial life its powerplant was a Baldwin-Lima-Hamilton RB-821 single-acting, two-cycle, 3000-bhp Diesel, The earliest Scandinavian motorships didn't even have traditional funnels since the engine exhaust could be ventilated quite simply by a simple exhaust pipe. Aesthetics eventually played a role and most motorships received a funnel that also included silencers while announcing the owner's livery, and even contained dog kennels on passenger vessels, or the radio shack or additional deck storage.
