Designed in April 1971 by Arthur Edmunds, the Mistress was the first center-cockpit boat to come to the market with a walk-through passageway connecting the fore and aft cabins. During the 1972 New York Boat Show, there were 15-20 people waiting in line to see the Mistress during the entire show. Known for its roomy interior and rugged construction, the Mistress was featured in the "Classic Plastic" article in the December 1997 issue of Cruising World. The Mistress is a very comfortable offshore boat with its keel-stepped main mast and two heads, great for making extended offshore passages. The center cockpit version includes a walk-in engineroom, an aft cabin with standing headroom, a workbench, and a fixed dinette table. Two versions of the center cockpit Mistress were produced, an aft-cabin, and a "Great Cabin" with the aft cabin extended all the way to the transom. A total of approximately 60 Mistresses were constructed, including the Mistress Mark III, an aft-cockpit version. The Mk III made excellent use of the smaller interior space it had, featuring berths for five, swivel chairs, and a drop-leaf dining table.
