DESIGNING AND BUILDING THE SELF-UNLOADER "CHARLES E. WILSON"

The features of the Great Lakes self-unloading Motor Vessel CHARLES E. WILSON which may be unique or unusual are discussed in this paper. The lines are filled out by a rounded bow and rake stern to give a gain in displacement of 1441 long tons as compared to the lines of the Great Lakes bulk carriers built 14 years ago. The lines were model tested against a hull with a pointed bow and conventional shipshape stern and had 14% less resistance. The hull is built of higher strength steel which saves 767 long tons in light ship weight with the same increase in cargo capacity. The ship has no boiler and has twin diesel main propulsion engines and electric heating for the quarters. For winter operation, a large water heater is installed to provide warm water for de-icing decks and hatch covers.
