A letter from President Ronald Reagan to the competitors at the 1981 United States Academic Decathlon. Reagan had been Governor of California when Academic Decathlon was originally formed and had met with the winners of the 1970 Orange County Academic Decathlon.
Where do I look for the hull identification number? The hull identification number (HIN) on all boats built after November 1, 1972 is permanently affixed to the rear of the transom usually on the upper right corner. It is required by federal law and must appear on the registration application. The HIN consists of 12 letters and numerals at least one-quarter inch tall that indicate the manufacturer, hull serial numbers and/or letters, and model year and/or month.
In air forces the serial number is used to uniquely identify individual aircraft and is usually painted on both sides of the aircraft fuselage, most often in the tail area, although in some cases the serial is painted on the side of the aircraft's fin/rudder(s).
