Designed by Charles Cunningham in 1954, this compact catamaran represents an early example of multihull design for recreational sailing. The Yvonne's twin-hull configuration with a single centerboard offers the stability advantages typical of catamarans while maintaining relatively simple construction suitable for owner-builders. With a length overall of just under 20 feet and a beam approaching 8 feet, this boat provides generous deck space and stability for its size. The fractional sloop rig delivers nearly 190 square feet of sail area, giving the lightweight 520-pound vessel impressive performance potential. The high sail area to displacement ratio of 46.92 indicates this is a boat designed for spirited sailing rather than heavy-weather cruising. Construction in either marine plywood or fiberglass reflects the practical, amateur-friendly nature of Cunningham's design. The shallow 3.28-foot draft makes the Yvonne well-suited for exploring shallow bays, protected coastal waters, and inland lakes where deeper-draft monohulls cannot venture. This catamaran appeals most to sailors seeking a fast, stable platform for day sailing and weekend coastal exploration. The twin-hull design provides excellent initial stability, making it particularly suitable for families or those new to sailing who appreciate a steady platform.
