For various reasons a boat cannot be raced every year.  Numbers will be retained for a boat that does not register to miss a maximum of 6 race seasons. An owner may voluntarily relinquish his number.  A sold boat may retain the number if the new owner desires, provided it is re-registered within 6 race seasons.  If two boats have the same number, the club recognizes the boat that held the number first will run as is, and the newer one will add (tape etc.) a temporary suffix number(s) or letter(s).  Examples: G35 B, G35 2, G35 JR etc.  The club may elect to honor a member by retiring a number, or granting permanent status of a number to a particular boat.
