Only twelve were built, beginning with Erivale. The first, Erivale, was launched in late 2003 for a UK owner, and examples have since spread around the world, from Hong Kong to Melbourne and San Francisco.
Design and Construction
Reducing resistance was central to the DK 46’s design. Its racing-optimised hull and foils were shaped to reduce wetted surface area and wave-making drag.The hull and foils were optimised for low resistance Rather than building stability into the hull form, the design treats it separately, using a substantial ballast package and deep fin. An SG iron fin and large lead bulb provide stability, while a carbon rudder and stock give accurate response and sensitive control.
The DK 46 was also a product of an unusually distributed development process. Mills Design in Europe, engineer FCS (John Fox) in the US, and DK Yachts in Malaysia collaborated on what was among the first sailboats anywhere to be completely designed and engineered—and to have its moulds built—directly from 3-D modelling software.
DK Yachts, described as one of the industry’s most technologically advanced builders, operated a dedicated drawing office and an eight-station IBM Catia drafting suite linked to a 25-meter, five-axis milling machine. For the DK 46 project, components had to be delivered as complete models, including rebates and flanges ready for assembly.
Rig, Cockpit, and Handling
The DK 46 was designed to perform across a broad range of conditions, combining light-air pace with speed in stronger breezes and on reaches. The preferred rig is a tall, carbon, two-spreader fractional arrangement, with halyards for both masthead and fractional spinnakers. Its dimensions were carefully adjusted to balance aspect ratios and sail areas while avoiding weakness in light conditions. Off the wind, masthead spinnakers flown from over-length poles set new performance levels in all conditions.
Twin carbon wheels place the helmsman well outboard for maximum visibility and close to the mainsheet and tactical crew. Underdeck mainsheet and traveller leads keep the working area tidy and free of snags while bringing the main controls to the trimmer.
The first hull quickly validated the concept, winning its first five races in varied conditions. It later beat Swan 45s, Corel 45s, and Ker 11.3s in Solent Winter Series Racing and the HWS Charity Pursuit Race. Hull 4, Zephyra, won the Rolex Big Boat Series in San Francisco.
Accommodation
Created with Mark Tucker of Design Unlimited, the interior reflects the DK 46’s dual role. The spacious, light saloon uses the full width of the central hull. The galley and navigation area run the full length of the starboard side, while a comfortable horseshoe-shaped settee sits to port. An open central passage allows access to sails while racing.
Forward of the mast is a double-berth cabin, with an adjacent head and hanging lockers. Aft of the companionway, buyers could choose among three arrangements:
- Two double-berth cabins
- One double-berth cabin to port and a double pipecot cabin to starboard
- An all-pipecot layout for the committed racing owner
Finishes and furnishings were coordinated throughout. In the cockpit, contoured seats and coamings provide relaxed comfort when cruising without getting in the way of efficient racing.
Known Issues
The available material describes no structural defects or recurring faults in the DK 46.
Verdict
The DK 46 is a rare, purpose-built IRC cruiser/racer that combines a technically advanced, software-driven construction process with a genuinely dual-purpose interior. Early hulls established a strong racing record across continents and conditions, while the accommodation shows serious thought for cruising. With only twelve boats built, however, any example that comes to market will be a specialist acquisition.
Pros
- Racing-optimised hull and foils, with low resistance and a separate stability package
- Tall carbon fractional rig with both masthead and fractional spinnaker capability
- Proven racing record from the first hull and subsequent boats
- Spacious, light saloon and a coordinated dual-purpose interior
Cons
- Only twelve built, limiting availability and fleet support
- Deep 9.84-foot draft restricts access to some cruising grounds
- Racing-oriented layouts may appeal more to committed racers than cruisers
