Designed by the legendary Rudy Choy and built by W. D. Schock Corp. from 1970 to 1972, this pioneering catamaran represents an important chapter in multihull development. With only twelve hulls produced during its brief production run, the Polynesian Concept stands as a rare example of early fiberglass catamaran construction. The boat's impressive 37-foot length overall paired with a generous 17-foot beam creates exceptional stability and spacious accommodations, while the twin daggerboard configuration provides excellent shallow-water performance and beaching capabilities. The masthead sloop rig carries 805 square feet of sail area, delivering spirited performance with the characteristic speed potential that made Choy's designs famous among multihull enthusiasts. At 5,500 pounds displacement, this catamaran offers the perfect balance between performance and load-carrying ability for extended coastal cruising or island hopping adventures. The sail area to displacement ratio of 41.46 indicates strong light-air performance, making it well-suited for tropical sailing conditions where it can truly shine. While production numbers were limited, the Polynesian Concept's Rudy Choy pedigree and Schock construction quality make it a sought-after vessel among vintage multihull collectors and serious cruising sailors seeking proven offshore capability.
