Davidson also sought to take advantage of the loophole in the IOR that had been exposed by the Britton Chance designed centreboarder Resolute Salmon in the 1976 One Ton Cup. With stability able to be achieved with internal ballast, the boat would gain a huge advantage over conventional fixed-keel Quarter Tonners, and so a centreboard was a designed as a central component of the yacht (the centreboard was just heavy enough to sink). The centreboard also allowed the yacht to be trailerable, so long as the beam was confined to the NZ trailering limit of 2.49m. A lifting rudder and skeg was contained in a cassette slot in the cockpit.

Fun wasn't launched in time for the 1976 NZ Quarter Ton nationals, but in the brief period before being shipped to Corpus Christi (Texas) she showed her competitiveness against the Whiting Magic Bus. Fun finished 5th overall in the Quarter Ton Cup, where a lack of time for tuning and crew training proved costly and meant that Fun was not able to reach her full potential, and a disqualification in the second race did not help her cause. Observers considered that Fun was the fastest yacht overall, however, especially on broad reaching legs
