Dynamical models for wide galaxy triplets with large characteristic galaxy crossing times (no less than the Hubble time) are constructed and studied using numerical simulations, taking into account the nonstationary state of ensembles of such wide systems. The results are applied to a statistical determination of the total masses of wide triplets using observational data from a new catalog of wide triplets. The analysis indicates the presence of considerable hidden mass in these systems.
