The results of hydrodynamical model calculations for the classic SBb(s) system NGC 1300 are presented and compared to high-resolution H I observations reported by England (1989). The effects of the various galactic components are investigated, and composite models are constructed in order to reproduce the gas observations and provide dynamical information on the galaxy. The models only partially reproduce the observations but nevertheless provide bounds for various dynamical parameters. The results indicate that either the models are too simplistic or nondynamical effects are important in the galaxy. 42 refs.
