The Orange Bowl Regatta was always one of the premier events on the racing circuit. The main event was the International Grand Prix. Boats from all over the world participated in this race. Prize money for the winner was $1,000 and the Engelhard Palladium Trophy (perpetual) valued at $25,000.

In December 1961, there were so many entries in the International Grand Prix race, three elimination heats were run. 
The respective heats were won by Ray Gassner in the Sunshine Baby IV, Skeeter Johnson in Bill Ritner’s Wa Wa Too and Don Wilson in Who Dat.  Most know of the Sunshine Baby, IV and Wa Wa Too, but not many know of the Who Dat. Unfortunately, the three never have to race each other as bad weather forced cancellation of the final race. The Southland Sweepstakes Regatta was always held on the first full weekend in February each year. So, the 1962 Southland committee organized a match race for these three boats.
The race was held on Saturday, February 3rd. 
Ray Gassner in the Sunshine Baby IV won the race, 
Skeeter Johnson in Bill Ritner’s Wa Wa Too second, 
and Don Wilson in Who Dat third.

Who Dat was built by Henry Lauterbach for Don Wilson in 1960. She was a sister boat to the Sunshine Baby IV. 
Don Wilson teamed with Briggs Cunningham (of Sebring auto racing fame) to install 6.5 Liter Maserati engine in the Who Dat for the purpose of winning the 1961 International Grand Prix at the Orange Bowl Regatta in Miami.
Here are a few photos of this unusual rig I took at the match race on Feb. 3, 1962.

The last time I saw the boat it was repowered with a blown 427 Chevy and was at the 1965 Nationals at St. Petersburg.
The boat was campaigning as Country Boy H-77 and was driven by Dave Thomas of Kettering, Ohio and owned by George Walther.
Then the hydro was converted for the 266 cu in class and was campained as F-33 Country Boy and driven by Salty Walther.
The hydro stayed an F-class hull the rest of it's life.

The boat was sold to Paul Gelpi and he ran her as Columbus Miss.
This photo was taken at Ypsilanti, Michigan in 1974.

After that it was sold to Don Null and he raced her as Fury.
This photo was taken on Lake Calhoun in Minneapolis, MN 1978.
Don ran the boat from 1975 until 1980.
The boat was destroyed and the owner/driver killed at Evansville, Indiana in 1980.

Sadly, we remember this great boat and her owners.
