The Formula 233 is considered to be the Genesis of offshore fishing boats - especially center consoles. It is a 23 foot 3 inch boat, or in short hand, 23'3" boat (hence the name: Formula 233). It was built with an 8 foot beam (although most of it's descendants are 8 1/2 feet.
The 233 was Don Aronow's first boat under the Formula name. It was designed by Jim Wynne. This was Aronow's first race boat and in collaboration with Jim Wynne and Walt Walters they founded the Formula Boat Company. This was in 1962. I think they Aronow won the Miami Nassau race in the 233. The 233 went on to win a number of offshore races while Aronow went on to found Cigarette, Magnum, Donzi and USA Racing. Aronow was murdered in 1987 by a rival boat builder.
Donald Joel Aronow (March 3, 1927 - February 3, 1987) was an American designer, builder and racer of the famous Cigarette, Donzi, and Formula speed boats. He built speedboats for the His Imperial Majesty Shah of Iran, Charles Keating, Robert Vesco, Malcolm Forbes, and George H. W. Bush. President Lyndon Johnson - in retirement - owned several 16 ft. Donzi speedboats on his Texas ranch with which he would race his Secret Service agents. Having made his money in the construction business in New Jersey in the late 1950s, Aronow moved to Miami in 1961 where he began racing boats for a hobby. By the end of 1962, he had formed the Formula Marine boat company which he then sold and in 1964 he started Donzi Marine.

Almost any offshore center console made is a descendant of the Formula 233 in one way or another. Most have lengthened their hulls and adapted over time, however, some still stay very close to their origins.
