The She 31 is a 30footodd fiberglass sloop drawn by Sparkman & Stephens and built in the United Kingdom by South Hants Engineering, the firm whose initials gave the marque its name. Introduced in 1969 from design number 1899, she earned the affectionate tag "baby Swan" among sailors who admired her clean, purposeful hull. Beneath that nickname sits a serious IORera racercruiser: a sweptback fin keel, skeghung rudder, and a hull shaped for handicap rule performance rather than casual lounging.

Design and Construction

The She 31's hull shape is optimized for racing under the IOR handicap system, with pinched bow and tail sections and a tumblehome amidships that give her a lean, race-bred silhouette capped by a sharp bow profile anchor. The fiberglass hull carries an iron fin keel carefully faired into the body, with that ballast quoted at 1,542 kg (3,400 lbs) and a swept-back fin keel paired to a skeg-hung rudder that affords good directional control and protection from grounding or collision damage. The deck is fiberglass as well, with a molded nonskid surface suited to wet-footed crew. Period build practice at South Hants used hand-laid laminates to Lloyds 100 A1 standards and a proprietary 'Shedeck' resin finish over the deck, though the authority review itself describes only the molded nonskid. At 7,800 lbs displacement on a 22-foot waterline, with a 43.6 percent ballast-displacement ratio, she is firmly in the dense, seakindly end of the 31-foot spectrum.

Rig and Handling

She carries a masthead sloop rig on an aluminum mast deck-stepped on a tabernacle, a detail that lets the stick be lowered for canal or bridge passages — a genuine cruising convenience inherited from her cross-Channel context. The mast has two sets of spreaders, and the standing rigging is stainless steel wire with swaged terminals and turnbuckles. Sail area is 410 sq ft; the mainsail uses slab reefing with two reef points while the genoa has roller furling for easy handling. On the water the review credits her as fast, close-winded and stable in nearly all sea conditions, and the skeg-hung rudder connects to a tiller that gives good feedback to the helmsman. The cockpit is spacious and well-protected by high coamings, with seats long enough to sleep on and lockers underneath, steered by that same tiller. Deck hardware is simple but functional: two primary winches, two halyard winches, two genoa tracks, two spinnaker poles and an anchor locker.

Accommodations

The earliest She 31 presented a limited interior with very little headroom, especially in the forecabin — a reflection of her initial racing orientation. The builder answered public demand with the 9.5 Traveller, a cruising version of the same hull with a redesigned deck, taller topsides and more living space. That Traveller layout is traditional: a V-berth forward, a saloon with two settee berths and folding pilot berths above, a starboard galley, a port navigation station and a quarter berth aft, plus a separate head compartment with marine toilet and washbasin. The veneers are varnished mahogany and the saloon stands 1.78 m (5 ft 11 in) tall. The base review still notes the She 31 proper as having a spacious and comfortable interior with plenty of headroom and stowage, suggesting later or revised fit-out brought the boat to that standard.

The Verdict

The She 31 is a Sparkman & Stephens design that wears its IOR pedigree with grace: a quick, close-winded sloop with a well-faired iron fin keel and a protective skeg rudder, wrapped in a fiberglass hull. Her deck-stepped tabernacle mast and roller-furling genoa speak to practical cruising, while the Traveller evolution shows a builder listening to owners who wanted headroom and a proper cabin. She is a compact, capable boat with a warm nickname and a serious bloodline.

Pros

  • Fast, close-winded and stable across most sea states
  • Skeg-hung rudder protects against grounding and collision damage
  • Tabernacle mast can be lowered for inland waterways
  • Iron fin keel carefully faired into the hull
  • Spacious, well-coamed cockpit with stowage seats

Cons

  • Original interior limited with poor forecabin headroom
  • Simple deck hardware assumes owner-handled sail changes
