Notes: This from 'SPB' who worked at the Peterson Design office at the time: "The PETERSON 34 was different approach to the IOR rule. Less rule influence in the stern sections. Designed to be the next class down from the One Tonners (sometimes jokingly referred to as a 7/8 Tonner)."\n \nSome boats to this same design were built in Argentina.\nAlt. short rig:\nI: 45.5'\nJ: 14.5'\nP: 40.3'\nE: 11.0'
