Welcome to Montgomery Model Boat Clubs (MMBC) newest class of racing boats, the Crackerbox! In an effort to attract more members and still operate the club in a fun, inexpensive and safe manner, effective May 2008, we expanded MMBC to include a class of semi-fast electric speed boats. This boat is based on a real class of boats. Several RC Clubs already include this class within their club…the closest to us being near Atlanta. It is a "drivers" boat, meaning you have to slow down in the turns to keep from rolling and if you go too fast down the straights, you might blow over. This adds to the challenge and fun. We adopt the below rules to begin with and can make adjustments as needed.

Full size fun!
