I'm looking for definitive evidence that Hunter Marine started manufacturing Hunter passage 42's earlier than 1990. I own Hull Identification Number (HIN) HUNP0022B090. As described by the regulations (and elsewhere), my HIN indicates I have hull #22, "B0" means my P-42 was manufactured in Feb 1990 and the "90" at the end means it is a 1990 model. Does anyone have an earlier hull number? If so, what is your HIN?
