Operational history

In a 2010 review Steve Henkel wrote, "Arthur Edmunds had his own design office for over 30 years, wrote the book ''Designing Power and Sail'' in 1998, and designed boats for Chris Craft and for Allied Boat Company (notably the Allied Princess 36 and Mistress 38). He fashioned this little vessel for S2 Yachts in 1975. She is a keel-centerboarder ... she is on the heavy side for a sailboat only 22 feet on deck ... Best features: Headroom at 5' 0" is quite good for a 22-footer ... She is definitely a cruiser, not a racer, so her PHRF of 261, while high, will not be of concern to most potential owners. Worst features: Her accommodation design and domed cabin may not appeal to everybody. That may be why her builders left her on the market for only three years."
