Sailing Performance & Handling
Under sail, the Motiva 47 behaves with the predictable, rhythmic motion of a vessel weighing approximately 20 to 22 tonnes. While its displacement-to-length ratio is high, the yacht is surprisingly agile once it finds its groove in a breeze exceeding 12 knots. Most 47s were rigged as ketches, a configuration that allows for a highly versatile sail plan; this "split rig" enables owners to maintain balance by reefing the mainsail while keeping the mizzen and a furling jib active in heavy weather.
The semi-long keel and protected rudder skeg provide exceptional tracking, allowing the boat to hold its course with minimal input from the helm or autopilot—a critical trait for shorthanded crossing. According to technical assessments of Borghegn’s designs, the hull’s center of buoyancy is carefully aligned with the center of effort to reduce weather helm even when pressed. In light airs, however, the 47’s significant wetted surface area requires a large reaching sail, such as a gennaker, to maintain momentum. Powering is usually handled by a robust 100–150 HP diesel engine (frequently Perkins or Volvo Penta), which provides the necessary thrust to push the heavy hull through steep head seas when the wind dies.
Interior Comfort & Variations
The Motiva 47 is renowned for its "Deck Saloon" or pilothouse configuration, which creates a seamless transition between the cockpit and the living quarters. The interior is characterized by an elevated seating area that offers 360-degree visibility, a feature that significantly reduces the fatigue associated with long watches in inclement weather. The fit-out was typically handled by the Tony Dahl Yard, resulting in high-end joinery—usually in teak or mahogany—that rivals the craftsmanship of premium Swedish builders like Hallberg-Rassy.
A key variation of this model is the Motiva 49, which is essentially the same hull and interior layout but features an integrated "sugar scoop" bathing platform at the stern, adding waterline length and storage. Inside, the 47 usually offers a massive owner’s aft cabin with a centerline queen berth and en-suite head, while the forward sections can be configured with one or two guest cabins. Because some hulls were sold for owner completion, buyers may encounter "home-finished" interiors that vary significantly from the professional Tony Dahl fit-outs; the latter are highly prized for their superior insulation and modular cabinetry.
Known Issues & Buyer’s Checklist
When inspecting a Motiva 47, the primary focus must be on the integrity of the steel and the effectiveness of the original coating system.
- Corrosion in "Hidden" Areas: Prospective buyers should use an ultrasonic thickness gauge to inspect the hull, particularly in the bilges under the engine and in the chain locker. Any areas where water may have trapped against the steel due to poor drainage can lead to localized pitting.
- Insulation and Condensation: Earlier or owner-finished units may lack professional-grade closed-cell spray foam insulation. Inadequate insulation leads to condensation behind the cabinetry, which can cause both mold issues and "inside-out" rust on the hull plating.
- Teak Deck Longevity: Many Motivas were delivered with teak decks fastened over the steel. If the fasteners or the caulking fail, moisture can migrate between the teak and the steel deck, leading to "crevice corrosion" that is expensive to remediate.
- Tankage Integrity: The fuel and water tanks are often integral to the hull. While this saves space, it means that any internal corrosion in the tanks requires cutting into the structure to repair. Verify the state of the tank baffles and coatings.
Community & Resources
Owners of Motiva yachts often find technical support through the broader Scandinavian steel boat community. While a dedicated "Motiva 47 Association" is not publicly prominent, the Dansk Forening for Lystsejlads (Danish Association for Pleasure Sailing) and various Nordic cruising clubs serve as hubs for technical data regarding Arne Borghegn’s designs. Documentation for these vessels is often archived in Danish, so connecting with local Danish surveyors who specialize in steel construction is recommended for international buyers.
The Verdict
The Motiva 47 is a "vault" of a sailboat, offering a level of security and comfort that few fiberglass boats can match. It is not a racing yacht, nor is it intended for casual weekend harbor hopping; it is a professional-grade tool for global exploration.
Pros
- Immense Strength: The round-bilge steel hull is capable of withstanding impacts that would compromise GRP hulls.
- True Pilothouse Living: The deck saloon provides a warm, dry environment for all-weather cruising.
- Exceptional Craftsmanship: Professional interiors by the Tony Dahl Yard are of heirloom quality.
Cons
- Maintenance Intensity: Steel requires a rigorous paint maintenance schedule to prevent oxidation.
- Weight: High displacement leads to sluggish performance in light winds (under 10 knots).
- Refit Complexity: Repairs to the hull or integral tanks often require specialized welding and sandblasting services.
