  We study the action and geometry of P-vortices, discriminating between the
percolating and finite clusters. We also discuss the interrelation of the
monopoles and P-vortices. To define P-vortices we use both the direct maximal
center projection and indirect maximal center projection. We find, in
particular, that the action density of the P-vortices in short clusters is
substantially higher than in the percolating cluster. The surface of the
percolating cluster appears random at short distances, with action density
depending on the shape.
