Factor X is a 28 Winslow Four-Sum, designed by Ralph E. Winslow in 1944 and built by Davies on City Island New York in 1946.
Factor X has had a single owner for the past 35 years and underwent an extensive professional rebuild by New England Shipwright in the 1990s with finish work by FL Tripp & Sons. Since her relaunch in 1998 she has been serviced by Tripps' and undergoing loving care by her owner with indoor storage each winter.
Factor X's planking is quarter-sawn Douglas Fir on white oak frames with bronze screws (the boats existing original planking that is above the waterline is rare quality Oregon Pine and Douglas Fir that were full length planks carried-over from US Navy wartime supply given City Island's role in building wartime wooden mine sweepers).
While Factor-X is a classic, it's simplicity, traditional lines, and seakeeping are its most noted attribute. A waterline of 23' 4" gives it a good turn of speed and it's high rig provides significant sail area for getting underway in light air. Her displacement, gentle hull shape, and high cockpit coamings make her comfortable and dry in heavy weather such as that common to Buzzards Bay, and her full keel and outboard rudder are attributes that avoid entanglements with lobster pots in areas such as Maine.
Factor X is very well cared for, both structurally, cosmetically and mechanically Her Yanmar 3GM 27 h.p. was installed at the time of her rebuild. Despite having low hours, it was removed and fully serviced two years ago, being reinstalled with a new shaft and new engine mounts. A year ago, the fuel tank that was installed in the rebuild was removed as a preventative maintenance measure and replaced with a new plastic tank that is easily inspected.
The mainsail is full-batten Quantum that is in good condition and the Quantum 135% genoa that is on a Schaefer roller-furler is in excellent condition having been purchased in 2019. Her 45' mast and boom are varnished Sitka spruce and constructed by Elk Spar of Bar Harbor, Maine at the time of her rebuild, using plans from Mystic Seaport archives.
'Factor X' is being offered at a very attractive and realistic price far below her true replacement cost. Come have a look!
Ralph Winslow was a highly regarded naval architect whose design for the Four-Sum was profiled in Rudder magazine in 1944. Winslow's ships plans are held in the collection of Mystic Seaport Museum and the plans were used for the boat's rebuild. The design is notable, too, for inspiring the design work of renown naval architect Chuck Paine who cites the Four-Sum as inspiration for his design Annie, which led to a series of Paine-designed boats built by Morris Yachts.
