On the other hand, the model code for the Malecite (another very popular model) was the character "6" so they didn't always use a letter code for the model. For example, the character "E" denoted an Explorer which was and is one of their most popular models. You have only 4 characters between the MIC and the model year, month of manufacture code so you are missing one.Īs to what model it is, MRC usually used a letter character immediately following the "MAD" MIC to identify the model which is probably what you want to know. The next 5 characters of the HIN could be used by the manufacturers any way they wished.

The first three characters of the HIN are the manufacturers identification code (MIC) and "MAD" indicates it is a Mad River which you already knew. Furthermore, this particular model year format was discontinued in August of 1984 so this format would not apply if the boat were built and registered in September of 1984. The boat HINs were registered on construction. The "M84" indicates the model year (1984) but model year changeovers typically occurred in August so this particular boat was probably built in September of 1983 for the 1984 model year. The "B" character indicates that the boat was constructed in September. This HIN follows a 12 character model year ("M") format. It might stand for an Airex foam core hybrid but that is only a guess. Mad River typically appended a "K" to the end of the HIN on their Kevlar boats. Most all HINs of that vintage, and all of those used by MRC to my knowledge, used a 12 character HIN. Are you sure you are not missing a character in that HIN (hull identification number).
