Design Brief & Intent
The Scanmar 345 was conceived as a high-quality, dual-purpose coastal and offshore cruiser that could easily be managed by a short-handed crew, yet possessed the speed and agility to participate in club racing. In an era dominated by heavy, underpowered cruisers and extreme, lightweight racing designs, Scanmar sought a middle path. The boat was designed to compete directly with premier European yachts of the period, such as the Dehler 34, Omega 36, and Westerly Storm 33. It distinguished itself through its superior Swedish construction, structural stiffness, and an incredibly smart use of interior volume.
The interior, designed by Nils-Erik Olofsson, is finished in hand-selected, satin-varnished mahogany, showcasing the shipyard's exceptional woodcraft. Olofsson prioritized ergonomics and safety at sea, installing handrails, rounded corners, and secure latching systems throughout the cabin. The woodwork is not merely decorative; it is deeply integrated into the hull's structural framing. While some mass-production builders of the late 1980s were transitioning to modular inner fiberglass liners to save assembly costs, the Scanmar 345 retained a traditional, robust build process that bonded bulkheads directly to the hull and deck. This meticulous fit-out created an exceptionally quiet, insulated, and draft-free living space, providing an excellent indoor climate that stands up well to cold-climate sailing.
Variations & Configurations
Throughout its production run, the Scanmar 345 stayed true to its core design, though subtle options existed to suit different regional sailing conditions. The boat is configured as a fractional sloop with a 7/8 rig, a design choice that prioritizes ease of handling. The standard sail plan was occasionally paired with a self-tacking jib track, a highly popular option for single-handed sailors navigating tight channels or the narrow fjords of Scandinavia.
Below the waterline, the standard configuration is a deep fin keel drawing 5.74 feet, paired with a balanced spade rudder. While most hulls were delivered with a high-aspect cast iron fin keel, the builder also offered a lead keel option on select hulls. The lead keel, being significantly denser, allowed for a slightly lower center of gravity, which improved righting moment and further enhanced the vessel’s stiffness.
The interior layout is remarkably clever, offering a highly split aft arrangement. It features a traditional V-berth forward with a removable infill. In the main saloon, two straight settees flank a centerline drop-leaf table, providing additional berths when needed. The L-shaped galley lies to port of the companionway, while an outboard-facing chart table with a swing-out navigator's seat sits to starboard. The true ingenuity lies aft: a spacious double cabin is situated to port, while a single aft cabin—often utilized as a sea berth or dry storage locker—is accessed directly through the starboard heads compartment. This innovative layout minimized wasted space and ensured that the head remained easily accessible from both the companionway and the cockpit.
Sailing Performance & Handling
Under sail, the Scanmar 345 is defined by its balanced, predictable, and rewarding manners. With a displacement of 11,023 pounds and a waterline length of 28.71 feet, the yacht has a displacement-to-length ratio of 207.95, positioning it firmly in the moderate-displacement cruising category. It is light enough to perform well in light air, yet heavy enough to slice through a chop without losing momentum. This is-complemented by an impressive ballast-to-displacement ratio of 39.0%, which translates directly to exceptional stiffness. The boat stands up to its canvas beautifully, allowing owners to carry full sail into moderate breezes before needing to reef.
The capsize screening ratio of 1.99 sits just below the ocean-safety threshold of 2.0, affirming its offshore capability and good stability characteristics. Coupled with a comfort ratio of 22.71, the boat behaves predictably in a seaway, offering a motion that is far more comfortable and less fatiguing than modern, light-displacement hulls with flat, wide sterns. The 7/8 fractional rig utilizes a large, powerful mainsail and a smaller, high-aspect jib. This setup makes tacking nearly effortless, as the headsail is small enough to sheet in quickly without requiring heavy winch work. Helming the Scanmar 345 is a tactile pleasure; the balanced spade rudder provides immediate, sharp feedback, and the boat tracks straight with minimal weather helm when properly trimmed.
Market Snapshot & Economics
Decades after the last hull left the yard in Bjästa, the Scanmar 345 remains a highly sought-after model on the European and North American brokerage markets. Because of its limited production run, finding one for sale requires patience, with listings appearing only occasionally. The boat commands a noticeable premium over mass-market production vessels of similar age, as buyers recognize the lasting value of Swedish craftsmanship and hand-laid solid fiberglass construction.
When evaluating a Scanmar 345, buyers should expect the pricing to reflect the vessel’s maintenance history and the status of its high-value systems. A well-maintained model that has undergone systematic upgrades will hold its value exceptionally well, while a neglected unit will require capital-intensive refits that can quickly exceed the boat’s initial purchase price. Due to the high quality of the initial build, these boats are excellent candidates for long-term ownership, but buyers must factor in the inevitable costs of updating original late-1980s systems to modern standards.
Known Issues & Triage
While the Scanmar 345 was built to higher structural standards than its predecessor, the Scanmar 33—completely eliminating the older model's tendency for minor keel-grid flexing, locally known as "swajköl" (swaying keel)—prospective buyers must conduct thorough due diligence. The transverse fiberglass floor frames and the longitudinal grid structure around the keel bolts should be closely examined for any signs of cracking or separation from the hull, which can indicate previous hard groundings.
Mechanically, most units were originally outfitted with the three-cylinder, 28-horsepower Volvo Penta 2003 diesel engine. This engine is generally reliable but has two well-documented vulnerabilities. First, the splines on the input shaft between the engine and the MS2 gearbox or saildrive are prone to wear down and strip over time, which can lead to a sudden loss of propulsion. Verifying the installation of a spline-saver kit or a modern dampener plate is a key inspection step. Second, the cold-start mechanism on the Volvo Penta 2003 is mechanically unique and must be operated correctly to avoid hard starting.
Additionally, because the boat features a saildrive configuration, the rubber hull diaphragm is a critical safety item. Volvo Penta recommends replacing this diaphragm every seven years. If the seller cannot produce receipts proving a recent replacement, this job should be scheduled immediately upon purchase. Finally, the deck is a fiberglass sandwich construction designed to prevent condensation in cold northern waters. Over time, poorly bedded deck hardware, stanchion bases, or chainplates can allow water to seep into the core, leading to localized rot or soft spots. Original laid teak decks, if present, are also highly likely to be at the end of their service life and should be meticulously inspected for failing caulking and water penetration.
Modernization & Upgrades
Modern owners of the Scanmar 345 are focused on preserving its excellent sailing characteristics while bringing its auxiliary systems into the 21st century. One of the most common and valuable upgrades is repowering. Replacing the aging, raw-water-cooled Volvo Penta 2003 with a modern, fresh-water-cooled diesel engine, such as a Beta Marine 30 or a Volvo Penta D1-30, dramatically improves reliability, fuel efficiency, and ease of maintenance. During a repower, owners frequently upgrade to a modern two- or three-blade folding propeller to minimize drag and maximize performance under sail.
Electrical system modernization is another high-yield upgrade. The original battery compartments, while compact, can be retrofitted with modern Lithium Iron Phosphate (LiFePO4) batteries. This conversion allows owners to triple their usable house battery capacity without increasing weight, making the integration of high-draw appliances, modern refrigeration, and sailing electronics much more feasible.
Additionally, because fractional rigs can sometimes feel underpowered downwind in light air, many owners install a removable bowsprit to fly an asymmetric spinnaker or a code-zero sail. This modification breathes new life into the boat’s light-air performance, making it a formidable and comfortable passagemaker in all wind conditions.
