21-cm H I data are used to compare galaxy masses derived from rotation curve analyses with masses computed from total profile widths. We find that linewidth masses may be used as accurate estimators of disk mass within the photometric diameter via Mopt/Msun = 103.7±0.15 ΔV20D(0)Δ. This result is used to determine the ratio of dynamic (virial) mass to galaxy mass for two Turner Gott groups.
