The AR could very well be the model, ie Arcadia. Not sure what the other numbers etc stand for. I know the 714 is not the hull number for this model, as only 305 or so were built. Might be the 714th built by Jeanneau for that year........
Anyway, I knew at the time JEN was not a jeanneau, but the IRI something or other was a Jeanneau hull number start. It does appear that this is the Cal version of the Jeanneau Rush. O'Day had a few Jeanneau models that they sold/built at the same time too. Not sure about Ranger or some of the other bangor-punta brands.
