I.M.P.B.A. Internats

Each year IMPBA holds an International Regatta where model boaters from throughout the membership gather together in competition events. National Championship trophies (US-1) are awarded for each class of Hydro, Mono, and Outboard based on 1/16 mile straight trophy trials, 1/3-mile oval trophy trials, and multi-boat heat racing. The host club may elect to offer special events for other classes as well.


Also awarded at the International Regatta is the Excellence of Performance Trophy (known as IMPBA's highest honor, and based on a weighted average of a single boat's performance in the 1/16 mile straightaway, the 1/3 mile oval, and multi-boat heat racing), the President's Cup Trophy (based on the best single performance of 2 boats in heat racing only), the William E. LeFeber Award (for outstanding sportsmanship and service to the organization), and the John Bridge Trophy (for the best total score with a multi-engine hydro in F class, U.S. 1 competition).
