A total of 50 optically selected polar ring galaxies, polar ring galaxy candidates and related objects were observed in the 21-cm H I line with the Nançay decimetric radio telescope and 31 were detected. The objects, selected by their optical morphology, are all north of declination -39$^\circ$, and generally relatively nearby (V< 8000  kms-1) and/or bright (mB< 15.5). The H I line data are presented for all 74 galaxies observed for the survey with the Effelsberg, Green Bank or Nançay radio telescopes, as well as all other published H I line parameters of these objects. Three objects were observed and detected by us at Parkes. A total of 59 objects were detected. For each object a brief description is given based on a literature search.
