Design and Construction
What distinguishes the Dehler 46 structurally is the vacuum-infused cored laminate set in vinylester resin, tied together by an integrated carbon-reinforced GRP grid that adds stiffness while the carbon keeps weight down anchor. The hull is chine-free with substantial aft flare, and the deck carries flush hatches throughout with cockpit coamings that ramp down gracefully to the deck as they run forward. A large backing plate at the keel attachment spreads loads well beyond the keel bolts themselves, and a watertight bulkhead sits just aft of a large forward sail locker, complete with molded-in steps that make a handy way to get down and inspect the chain in the anchor locker. The transom drops down manually to form a swim platform, with a vertical transom-mounted handle and an emergency ladder that pulls from a cubby.
Keel choice is unusually flexible: four configurations are offered, with shoal draft at 6 feet 1 inch, moderate at 7 feet 4 inches, and deep at 8 feet 2 inches, the latter two being T-shaped, while a fourth deep option is L-shaped to help keep vegetation from trapping on the appendage anchor. The rudder is a single spade, and the builder's moderate length-to-beam ratio of 3.2 keeps the hull balanced without excessive beam.
Rig and Handling
The standard fractional rig carries a tapered, keel-stepped Seldén aluminium mast with double sweptback spreaders, and total working sail area of 1,228 square feet is split between a 106-percent genoa and a traditional full-battened mainsail. A hydraulic backstay lets you tweak sail shape to maximize speed, and a self-tacking jib is available for easier short-handed work. For those chasing numbers, a competition rig sheds roughly 770 pounds and adds around 150 square feet of sail from a Pauger carbon mast and boom on rod rigging. Jib tracks sit well inboard against the cabintrunk for tight sheeting, while chainplates remain outboard behind a cosmetic cover plate that grants access once removed. All halyards and reefing lines lead aft in under-deck conduits to Spinlock clutches and a pair of Lewmar winches, with the primaries slightly elevated on the coamings and a double-ended German mainsheet system tracking the traveler across the cockpit sole ahead of twin wheels.
On the water, test sailors found her light on the helm even with full canvas drawing, and she tracked well anchor. In protected bay conditions they scooted along at 8.6 knots in 17 knots of breeze at a 45-degree apparent wind angle, holding most of that speed to about 38 degrees AWA, and still managed 7.9 knots on a beam reach in 13 knots before falling to 6 knots at 120 degrees. Wide-open throttle at 2,950 rpm eked out 8.7 knots under the 53-horsepower Volvo Penta saildrive, with a 75-horsepower option available.
Accommodations
Below, the Dehler 46 offers two- or three-cabin layouts with two heads. The forward master suite centers on an island berth with an ensuite head and shower compartment, while a full guest cabin lies to starboard just aft of the L-shaped galley fitted with Isotherm refrigeration and an Eno stove. The port aft cabin can be a double or a single with extra storage but has no cockpit access. A drop-leaf centerline table with a pop-up light carries a stainless handrail sloping to mirror the cabintop eyebrow, and everything is covered or hidden—from the forward-facing nav panel to a pop-up bottle compartment—with matching lockers, rounded tops, and movable headrest cushions reminiscent of an airliner. Head doors can isolate just the toilet or the whole compartment, and joinery is mahogany as standard with teak or Italian oak offered.
Known Issues
A practical caution from testers: the saloon table handrail makes a fine handhold until you slide your hand forward where the gap narrows enough to pinch your fingers anchor. It is a small but real detail to flag for crews with children or short reach.
Refits and Ownership
Factory option packs shape the ownership profile. The Cruising Pack bundles the cockpit table, bathing platform, spring cleats, Ultra anchor, and a 320-amp house battery upgrade, while the Navigation Pack adds a B&G Zeus2 plotter, H5000 instruments, and autopilot. An optional composite sprit allows flying an asymmetrical for reaching performance. Tankage is ample at 119 gallons water and 58 gallons fuel for coastal use, and the open, uncluttered deck with ramped coamings and flush hatches speaks to a boat designed for both racing conversion and relaxed cruising.
The Verdict
The Dehler 46 is a thoughtfully engineered modern performance cruiser that rewards the sailor who wants real speed without sacrificing livable accommodations. The carbon grid and flexible keel program show a builder intent on structural integrity and versatility, and the flush, ramped deck is as functional as it is clean.
Pros
- Vacuum-infused cored hull with integrated carbon grid for stiffness without weight penalty
- Four keel options including L-shaped deep draft for weed-prone waters
- Light helm and strong light- to mid-air performance under fractional rig
- Flexible two- or three-cabin interior with clever hidden storage and head doors
Cons
- Table handrail gap can pinch fingers at the forward end
- Port aft cabin lacks cockpit access
- Competition rig and options add complexity and cost for casual cruisers
