Abstract
The rotation curves are constructed for 81 flat galaxies from the FGC catal og with apparent axial ratios a/b > 8 and declinations > +38 degrees. The t ypical rotation curve extends to 0.86 of the standard galaxy radius. Almost all of the galaxies studied have nondescending rotation curves; some of th em show evidence of waviness and asymmetry, which appears to be the result of clumpy absorption in the galaxy disks. The median radial velocity of the galaxies from our sample is 7620 km s(-1).
