The CVV 8 Bonaventura (English: Good Adventure) was a two-seat competition glider designed and built in Italy during the 1950s.

The Bonaventura was designed at the Centro Volo a Vela (CVV), or Experimental Soaring Centre, of the Royal Polytechnic of Milan by Gildo Preti; though construction was started in 1952, the prototype was not completed until 1957.

[1] The Bonaventura is an all wood aircraft with a 19 m (62 ft 4 in) span, shoulder mounted wing, built around a single spar.

The tandem seats are enclosed ahead of the wing leading edge under a starboard hinged, continuous canopy.

[1] Two Bonaventura prototypes were built by CVV, followed by a short production run of thirteen from Avionautica Rio.
