UFO 31 Buyer's Guide
Shopping the brokerage market for a UFO 31 means looking at a Holman & Pye-designed, Colvic Craft-molded masthead sloop from the mid-1970s, offered both factory-finished and as a home-completion shell. That dual history matters more than any single equipment list, because the boat you inspect may have been finished by a professional yard or completed by an amateur, and the quality of the interior and systems can vary accordingly.
Layouts on the Used Market
The UFO 31 is a 30-foot-10-inch fin-keel monohull with about 25.6 feet of waterline inside a ten-foot beam. No source itemizes the berth plan or cabin sections, so used layouts should be judged boat by boat. The iron keel and solid fiberglass hull and deck are constant; the variable is the fit-out quality from the home-completion route.
Equipment and Common Upgrades
On the used market, autopilots, life rafts, solar, spinnakers, and chartplotters are commonly fitted, meaning a buyer can usually expect modern navigation and safety kit already aboard. A dodger and a short-handed setup are often seen, which speaks to comfort and reduced-crew sail handling as typical owner priorities. The practical takeaway is that power and energy (solar, autopilot), canvas and sail handling (dodger, short-handed rigging), and navigation (chartplotter, life raft, spinnaker) are the clusters that define a well-equipped example, while lesser items are simply omitted from consideration.
What to Inspect
Because the UFO 31 was sold as a home-completed shell, the quality of each boat may vary and a careful survey of the interior joiner, tabbing, and systems installation is warranted on any example. The iron keel should be checked for corrosion and the solid fiberglass hull and deck for osmotic or impact damage. Verify rigging against the known dimensions—halyards at 90.6 feet by 3/8 inch, genoa sheets at 30.8 feet by 1/2 inch—since a home-built finish may have used off-spec lengths.
Availability and Buyer's Takeaway
Typical markets for the UFO 31 are the United Kingdom and the Netherlands. For a buyer, the checklist is short: confirm whether the boat was factory- or home-finished, survey the interior thoroughly, check the iron keel and solid glass hull, and verify the rigging matches specification. A commonly fitted electronics and safety suite is a bonus rather than a given, and the slightly underrigged masthead rig responds well to a 135 percent genoa if the prior owner fitted one.
