Scanmar 345 Information, Review, Specs

Sailing Performance & Handling

The Scanmar 345 is defined by its 7/8 fractional rig, a configuration that offers significant advantages for short-handed cruising. Unlike the heavy masthead rigs common in the early 1980s, the 345's sail plan utilizes a large, powerful mainsail and a smaller, more manageable headsail. This setup, often paired with a self-tacking jib track, allows the boat to be tacked with minimal effort from the helm. With a displacement-to-length (D/L) ratio of approximately 208 and a ballast ratio near 39%, the hull strikes a balance between "moderate racer" and stable cruiser.

Under sail, the boat is known for its "well-mannered" behavior, a trait Magnusson designs are celebrated for. The lead fin keel provides a low center of gravity, allowing the boat to stand up well to its canvas in a breeze. While the motion comfort ratio is technically in the coastal cruiser range, owners frequently report that the hull's shape and weight distribution provide a surprisingly dry ride in choppy conditions. The steering is typically light and responsive via a Whitlock wheel system, though some earlier versions may have been fitted with a tiller.

Interior Comfort & Variations

The interior of the Scanmar 345 is a showcase of traditional Swedish mahogany joinery, designed by Nils-Erik Olofsson with a focus on ergonomics. Unlike the "keyhole" aft cabin entry found on the Scanmar 33, the 345 offers a more open transition and improved headroom throughout the cabin, which averages around 1.85 meters (6'1"). The layout typically includes a V-berth forward, a spacious salon with two straight settees that double as berths, and a large L-shaped galley to starboard.

A notable feature of the 345 is its aft cabin arrangement. While the Scanmar 33 was sometimes criticized for a cramped aft space, the 345's redesigned transom allowed for a more generous double berth and additional stowage. The head compartment is located aft to port, strategically positioned near the companionway for easy access while underway. Sibling models built on the same principles include the Scanmar 31 and the larger, center-cockpit Scanmar 35, though the 345 is often considered the most balanced "aft-cockpit" design in the range.

Known Issues & Buyer’s Checklist

Prospective buyers should approach a Scanmar 345 with a focused technical checklist, as these vessels are now entering their fourth decade:

• Keel Floor Reinforcement: While the 345 was built to higher standards than the early Scanmar 33s—which sometimes suffered from "swaying keel" (swajköl) due to insufficient floor timbers—it is essential to inspect the keel-to-hull joint and the internal grid for signs of stress or previous grounding.
• Engine Service: Most units were originally fitted with the Volvo Penta 2003 series diesel engine (28hp). While reliable, this engine is known for issues with its cold-start mechanism and the splines on the MS2 gearbox/saildrive. Verify that the saildrive diaphragm has been replaced within the last seven years.
• Deck Core Integrity: The deck is a GRP sandwich construction. Check for "crunchy" spots or soft areas around high-load fittings like the chainplates and stanchion bases, which may indicate water ingress into the core material.
• Teak Deck Maintenance: Many Scanmars were delivered with laid teak decks. If original, these are likely reaching the end of their service life; look for thinning planks or failing caulking that could lead to core rot.

Community & Resources

The most significant technical resource for this model is the Scanmar Owners Association, a UK-based organization that maintains a repository of technical manuals, original brochures, and owner-sourced modifications. They offer a deep well of knowledge regarding parts compatibility and direct contact with the Swedish heritage of the brand.

The Verdict

Pros:

• Excellent build quality with high-end Swedish mahogany interiors.
• The fractional rig and self-tacking jib make it an ideal choice for solo or couple cruising.
• A balanced hull design that offers a competitive turn of speed for its class.

Cons:

• Maintenance of the aging Volvo Penta 2003 engine can be costly.
• Limited production numbers (approx. 100) make them difficult to find on the secondary market.
• Standard draft of 1.75m may be restrictive for some thin-water cruising grounds.
