From "RB Sailing blog": "Andrews also notes that Allegiance has a near sister Impact, which was ordered after the owners sailed in Allegiance’s sea trials. The main difference was Impact had a masthead rig and slightly wider stern. Impact has won many California races including the San Francisco Perpetual Cup match race in which she defeated Irv Loube’s Beneteau One-Tonner "Bravura" and the SoCal IOR Championships."
