Sailing Performance & Handling
The Dehler 46 SQ is engineered to bridge the gap between high-volume production cruisers and elite performance yachts like X-Yachts or Arcona. With a standard Displacement/Length (D/L) ratio of 149 and a Sail Area/Displacement (SA/D) ratio of 22.8, the yacht is optimized for light-to-medium air efficiency. Upgrading to the Competition rig—which includes a taller carbon mast and a 2.58m deep-keel—pushes the SA/D to a potent 25.59, as noted by Sailing Magazine.
At the helm, the yacht features a single-rudder configuration connected to a Jefa steering system, which provides a direct and tactile feel often lost in twin-rudder designs. Editorial testing by Yachting Monthly in Force 6 conditions revealed that the yacht tracks exceptionally well upwind, maintaining a 40-degree true wind angle with minimal slamming due to its relatively fine entry. The addition of an integrated bowsprit with a bobstay allows for higher luff tension on Code 0 and gennaker sails, facilitating palpable acceleration that can push the hull toward double-digit speeds on a reach.
Interior Comfort & Variations
The interior of the Dehler 46 SQ focuses on maximizing natural light and modularity. Compared to the original 46, the SQ features significantly larger hull windows and additional coachroof ports. The saloon is highly configurable; a standout feature is the electric sliding bench on the port side, which can be moved toward the table to create a full-width dining area or retracted to open up the passageway to the forward cabin.
The master suite in the bow utilizes a "Hidden Door" concept where the en-suite bathroom door also serves to close off the head compartment, maximizing space in the cabin. Materials typically range from standard ALPI light oak to optional mahogany or teak finishes. A unique design choice is the orientation of the 57hp (or optional 80hp) Yanmar engine; Dehler reversed the engine's position, placing the saildrive at the forward end under the companionway steps to prevent the engine box from encroaching on the aft cabin berths.
Popular Mentions & Media
While the "SQ" variant is relatively new, the Dehler 46 hull has a decorated racing pedigree. According to regional distributors like Windcraft Yachts, the model has successfully competed in blue-water classics including the Rolex Sydney to Hobart Yacht Race and the Transpac race from Los Angeles to Hawaii. These successes have cemented the 46's reputation as a "Corinthian" racer capable of crossing oceans competitively without sacrificing the amenities required for family cruising.
Known Issues & Buyer’s Checklist
Prospective buyers should focus on a few specific technical areas identified by professional testers and long-term owners:
- Electronics Wiring Access: Editorial reviews have noted that while the overall finish is high, access to the primary electronics wiring can be tight, complicating aftermarket installations or repairs.
- Locker Depth: The "SQ" redesign of the saloon lockers includes a bottom-hinged door that creates a small internal shelf; while aesthetic, it reduces the total usable volume by approximately 10cm compared to the previous flat-bottomed lockers.
- Mainsheet Purchase: The German mainsheet system is rigged with a 2:1 purchase led to winches at the helm. In heavy air, owners often find that standard winch handles are insufficient for the load, recommending longer handles or the optional electric winches.
- Saildrive Service: Because the engine and saildrive are reversed (saildrive forward), traditional service access points are shifted. Ensure the saildrive bellows and seals are inspected through the dedicated hatches in the aft cabins.
Community & Resources
The Dehler community is supported by a robust network of owners and technical resources. The Dehler Owners Association remains the primary body for technical data, while Hanse Group (the parent company) provides archived manuals and parts support for the SQ line.
The Verdict
The Dehler 46 SQ is a sophisticated update that polishes an already successful design. It appeals to the sailor who demands a boat that is "blisteringly quick" on the racecourse but refined enough for extended coastal cruising.
Pros:
- Exceptional stiffness and weight savings due to vacuum-infusion and carbon reinforcement.
- High level of modularity in the saloon and navigation station layouts.
- Excellent helm feedback from the Jefa steering and single-rudder setup.
- Integrated bowsprit and flatdeck furler come as standard performance upgrades.
Cons:
- The high-end performance options (carbon rig, competition keel) significantly increase the base price.
- Saloon storage volume is slightly compromised by the new locker door design.
- Standard mainsheet purchase requires significant physical effort in heavy weather without electric assistance.
