This board's history is a mystery.
In Australia this design had a short but well publicised life circa 1971 - 1972.
Following the experimentation with the Twin fin 1, several designers used variations of tri-fin configurations. The rail fins were usually small and long based, the inside often foiled flat. Position varied enomously from behind to well in front of the central fin.
This early experimentation established the principle that pocentral fin would stiffen the board and make it track, while a position in front of the fin would loosen up the board and make it msitioning behind the ore manourvable.
Narrowing the angle of attack and tipping out of the side fins was a progressive process that produced the Cambell Bros.' 1973 Bonzer, a combined fin and bottom design based on Ruellego Delta designs. The original design , with leading rail fins, was retained on many kneeboards 1971 to 1976, see Crozier #58
The Tri fin was to reach its peak with the development of Simon Anderson's Thruster (1981) design, placing three similar fins at the tail extemities to maximize manouvreability in small waves. It was subsequently found to superior to all previous designs..
