This is the second part of a pair of the studies which report the vertical sloshing, that is, the liquid surface motion in container oscillating in the vertical direction, concerning various equilateral-polygonal-section containers: namely, octagonal, heptagonal, hexagonal, pentagonal, square and trianglar containers together with a circular container, in order to generalise their sloshing modes. As a result, the stability diagrams for all the polygonal-section containers are investigated by both experiments and computations. Furthermore, it is found that the equivalent diameter d_<el> based on the hydraulic mean depth is the most adequate as a characteristic length scale to classify all the sloshing modes. The authors show an unified formula to predict the eigen frequencies, using d_<e1> together with the modal classification proposed in the first part.
