Dehler 31 Sailboat Review, Specs, and Listings

Design and Construction

The hull is solid fiberglass laminate laid up by hand, while the deck is a sandwich structure and the floor assembly is molded GRP, with a cast-iron keel carrying the ballast. Dehler's fully bonded deck-to-hull joint—the yard's monocoque method of laminating the two shells together inside the mold—yields a strong yet light structure that Yachting Monthly credited as the reason the boat remains a credible performance cruiser despite the weight savings. The shallow bilges were bone dry in survey, and the top-quality resins used in construction have kept the hull free of osmosis. Below the waterline, later 31s received a tapered keel and deep elliptical rudder that keep ballast low and improve grip when heeled, an update consistent with the boat's stiff, manageable character under sail.

Rig and Handling

At a displacement of roughly 3,200 kg with a ballast ratio near 44 percent, the Dehler 31 is a stiff boat that can be pushed for an extra knot without becoming unmanageable, yet her lightness makes her a physical boat to sail in rough conditions. The tiller version sails excellently, with comfortable coaming space and all necessary control lines within easy reach; the cockpit is narrow enough to brace against the opposite side when heeled, and the closed transom makes it feel secure. Dehler fitted good-quality deck gear from new, and the boat still presents as a quality item. The tiller could be swapped for a wheel on request, and a Whitlock column was offered as an option and even retrofitted by some owners—but the cockpit was never built to accept a wheel, being too narrow behind the traveler and not rigid enough, and on wheel-equipped boats the pillar wobbles, the helmsman is cramped, and reaching the mainsheet is awkward.

Accommodations

Below deck, white surfaces dominate and the saloon is kept cosy and aisle-like with mahogany veneers, though the boat's external dimensions are less generous than a Bavaria's and the spatial conditions are cramped. Headroom in the saloon is 1.83 metres, decreasing forward, while the wet room stands 1.71 metres; Yachting Monthly similarly noted plenty of headroom in the saloon but a quick taper in the forecabin. The saloon berths are easy to use thanks to folding-back cushions, but it is not possible to sit upright on the fore or aft bunks to dress. The foredeck berth runs right to the bow, rendering its 2.30-metre length unusable. A sliding door fronts the WC room and overlaps the chart table at the aft end of the starboard saloon berth; the heads hold a generous wet locker aft of the toilet. Water tank sits forward and fuel aft, leaving bunk storage clear. Deep-drawn ABS parts on floor and ceiling keep weight down, and wooden floorboards usually hide under a Dehler fitted carpet.

Known Issues

The aft ceiling paneling is a velvet-substitute material that collects dirt and looks unsightly with age, and yellowed plastic trim is a known shortcoming; the plastic molded headlining itself was free of sagging or stains in review. The wheel-steering conversion is the most consequential defect of intent rather than material: the cockpit simply does not suit it. Buyers and owners should regard the tiller as the boat's intended helm.

The Verdict

The Dehler 31 is a van de Stadt–penned light cruiser that rewards the tiller helmsman with excellent handling and a stiff, quick motion, wrapped in Dehler's bonded construction that has proven osmotically clean. Her compromises are interior: cramped quarters, unusable foreberth length, and a headroom taper that limits forward comfort. As a used prospect she is best appreciated as a performance family cruiser rather than a volume-packing coastal boat.
