阻力测量是在一个钝基旋转体上加上几个可供选择的船尾后体进行的。这些后体中最好的一种，其长度仅为最大直径的60%，其减阻效果几乎与常规流线型尾翼一样。测量了不同长度的物体上的压力分布。目前似乎还不可能定量地预测这类物体的阻力，但已提出了一些定性的设计原则。
Drag measurements were made on a blunt-based body of revolution with the addition of several alternative boat-tailed afterbodies. The best of these afterbodies, with a length of only 60 per cent of the maximum diameter, gave almost as much reduction of drag as a conventional streamline tail. The pressure distribution on this body was measured for various lengths. It does not seem to be possible at present to predict quantitatively the drag of this type of body but some qualitative design principles have been suggested.
