3x races for 2020 will form the UIM National Championships. OMRA will be racing under UIM rules for these races which are already very similar to OMRA rules in the Offshore Category. The full rule book, which covers inland lake racing, hydro racing and a few other types is hundreds of pages long. Only the pages relevant to OMRA and Offshore RC Racing have been included. The classes are divided in a similar fashion to OMRA with slightly different terminology, however most drivers will be falling into these categories for 2020. OF-1/4 - C Class Drivers O27 - D Class Drivers O35 - E Class Drivers We have put in a request for an electric drivetrain category be added which should be listed soon. We will be sending out vinyls for flags and UIM logos for boats in the next couple of weeks. You are free to look over the UIM rules for Offshore Racing ahead of the upcoming races. DOWNLOAD HERE
