  I use the largest available sample of Type II plateau supernovae to examine
the previously reported luminosity-velocity relation. This study confirms such
relation which permits one to standardize the luminosities of these objects
from a spectroscopic measurement of their envelope velocities, and use them as
extragalactic distance indicators. The "standard candle method" (SCM) yields a
Hubble diagram with a dispersion of 0.3 mag, which implies that the SCM
produces distances with a precision of 15%. Using two nearby supernovae with
Cepheid distances I find Ho=81+/-10 km/s/Mpc, which compares with Ho=74 derived
from Type Ia supernovae.
