How to Read the Hull ID Number (HIN)

These two tables will help you determine the model and year of your MacGregor or Venture. There was no Federal requirement for Hull Identification Numbers (HIN) prior to 1973. All Ventures and MacGregors built during and after 1973 will have a HIN placed on the upper Starboard side of the transom.

The format after 1980

mmm = Manufacturer US Identification Code
   h     = Model description (see Production Years - HIN Designation.)
 ssss   = Hull Serial Number
  dd    = Date of Manufacture -
      Where A to L = Month starting with January and then
