This registry is dedicated to preserving the heritage of Don Aronow's famous Formula 233. A place to network with other 233 owners, discuss technical issues, get and give advice, exchange knowledge and compile a database of the remaining 233's. If you've ended up here you've got some connection to a 233. Special thanks to HORBA for providing images. Please visit the Historic Offshore Race Boat Association , an organization dedicated to educating the public about the history of offshore racing. Welcome and thanks for visiting.
