A 2-foot chord, 12 percent thick, symmetric strut was towed vertically in the high-speed basin at Naval Ship Research and Development Center (NAVSHIPRANDCEN). The purpose of the experiment was to extend a study of the effect of aspect ratio on surface piercing strut ventilation characteristics and to determine the effect of a strut surface proturberance on these characteristics. Increasing the aspect ratio increased the susceptibility to ventilation. A proturberance which extended a small distance below the free surface on the low-pressure side reduced side force coefficients and increased susceptibility to ventilation. The effect of the proturberance when positioned just aft of the leading edge was more pronounced than at midchord or further aft.
