The towing-tank data for model prismatic planing boats have been collected from 23 sources and collated into 15 appropriate groups; 7 of these groups are reasonably systematic in nature while the remaining 8 groups are less systematic. The specific data are the lift and the center of pressure. Regression analysis has been applied to these two quantities and the resulting formulas compared to the predictions of 5 out of 7 previously published semiempirical theories. Finally, the experimental data for the lift and drag have been correlated with the idealized keel-normal pressure force and keel-parallel frictional force. This correlation is shown to be much improved providing one accounts for the fact that the frictional force does not act parallel to the keel of the model, but at a realistic angle to it.

已从23个来源收集了棱柱形滑行艇模型的拖船数据，并整理为15个适当的组。这些组中有7个在本质上是合理的系统化，而其余8个则较不系统。具体数据是升程和压力中心。对这两个量进行了回归分析，并将所得的公式与7种先前发表的半经验理论中的5种的预测进行了比较。最后，升力和阻力的实验数据已经与理想的龙骨法向压力和龙骨平行摩擦力相关联。如果考虑到摩擦力并不平行于模型的龙骨，而是与模型的龙骨平行地作用，则表明这种相关性得到了极大的改善。
