International J/22 Class Rule Excerpt: 2.9 Measurement
“A yacht shall only be measured by a measurer recognized by his National Sailing Authority and the International J/22 Class Association. A yacht shall not be recognized as a J/22 until its official measurement certificate is registered with the IJ22CA”

To obtain a measurement certificate:
New Boat – It comes with the Measurement Certificate partially completed by Builder.
Used Boat – Change of ownership invalidates the Measurement Certificate and the new owner should in his/her interest advise his/her Class Office. A measurer in your district will contact you. If the previous owner has a valid Measurement Certificate, and you have not made ANY alteration to your J/22, submit to the measurer the information required in Part A of the Measurement Certificate together with the previous owner’s Certificate. Otherwise, make arrangement with your Measurer to have your J/22 re-measured.
