Re: Where can I look up my model year for pre nov '72 Oday 2
The "CLASS#" is part of the HIN on later boats, for example: XDYA07450573 is a 1973 model 22. XDY = O'DAY, A = 22, 0745 = Class# or Sail#, and 0573 means the boat was built in May of 1973. Some later boats (all classes) used Myym for the Model year indication where M = model year format, yy = Model year (last 2 digits of) and m - the Letter code for the month. The Model years ran August to July, so for 1977 the model year ran August 1976 to July 1977.
3239 seems low for the Hull# on a boat built in 1972-3 (I seem to recall 1972 was first year for the 22), my 1969 model Widgeon was Hull # 22698 and Hull# refered to TOTAL production of O'Days, not just that model. Perhaps they changed the format?
