About the Show 34 Sailboat

Doug Peterson's Show 34 emerged in 1974 as a sophisticated performance cruiser that perfectly captures the era's emphasis on racing-influenced design for serious sailors. Built by Italy's Barberis yard, this 33.67-foot masthead sloop demonstrates Peterson's talent for creating boats that excel both on the racecourse and during extended cruising adventures. The hull showcases classic Peterson characteristics: a fine entry, moderate beam of 10.86 feet, and a fin keel with spade rudder configuration that delivers responsive handling and impressive windward ability. With 4,400 pounds of ballast in her 10,780-pound displacement, the Show 34 carries sufficient stability for offshore work while maintaining the light, quick feel that racing sailors appreciate. Her sail area to displacement ratio of 18.03 indicates spirited performance in light to moderate conditions, while the comfort ratio of 23.85 suggests a motion that favors speed over ultimate seakeeping comfort. The capsize screening formula of 1.97 falls within acceptable parameters for coastal and offshore sailing. Italian construction quality shines through in the fiberglass layup and interior joinery. This relatively rare design appeals to sailors seeking a proven performer that can handle serious cruising while maintaining the responsive characteristics that made Peterson's designs legendary during sailing's golden age of the 1970s.
