Farr 1104
Description
The Farr 1104 (also known as the Farr 10.20 or Farr 1104) is a classic IOR (International Offshore Rule) racing sailboat designed by Bruce Farr in 1975–1976 (design number 51, his first full IOR race boat commission). It was built primarily in Australia and New Zealand by yards like Compass Yachts (Sydney) and others (e.g., Holmes in AUS, some in Tauranga NZ), with launches starting around 1976 (e.g., early boat "Prospect of Ponsonby" in 1975/1976). About 50–100 hulls were produced, many still racing or cruising today—especially in New Zealand/Australia fleets, where it's considered one of Farr's best early designs for performance and balance. The boat was optimized for IOR racing (e.g., Southern Cross Cup, club events), with a fast, light-displacement hull, fin keel, spade rudder, and fractional sloop rig for excellent upwind pointing and reaching speed. It has a reputation as a "great all-rounder"—quick in moderate winds, stable, and capable offshore, though more racer than plush cruiser (interior is functional but compact/miniaturized for weight savings).
