The CR 310 is a quintessential example of the "Orust quality" that has come to define Swedish boatbuilding. Produced by CR Yachts in Henån—the same maritime hub that hosts legends like Hallberg-Rassy and Najad—the 310 was designed by Benny Josefsson to offer a performance-oriented alternative to the heavier Scandinavian cruisers of its era. It represents a transition point for the yard, moving toward a more modern hull shape with a flatter underbody and a more powerful fractional rig, while maintaining the handcrafted mahogany interiors that are a hallmark of the CR Yachts brand. Unlike many 31-footers designed for the charter market, the CR 310 was built specifically for private owners who prioritize structural integrity and "big boat" feel in a manageable, sub-10-meter footprint.

Sailing Performance & Handling

The CR 310 is frequently described as a "sailor’s boat" due to its responsive handling and balanced helm. Equipped with a 7/8 fractional rig and swept-back spreaders, the boat does not require a permanent backstay for rig tension, allowing for a large, powerful mainsail and a smaller, easily tacked headsail. This setup is particularly effective for shorthanded coastal cruising.

In terms of sea-kindliness, the 310 benefits from a relatively deep fin keel and a high ballast ratio, which keeps the boat stiff and capable of punching through a chop without excessive slamming. Owners and testers often note that while it lacks the sheer mass of an older heavy-displacement cruiser, its tracking is superior to many modern Mediterranean-style hulls. According to technical specifications maintained by the manufacturer, the boat’s displacement-to-length ratio suggests a nimble performer that excels in light-to-moderate air, yet remains predictable when the breeze freshens. The rudder is semi-balanced, providing enough feedback to feel the "groove" of the boat without being physically taxing over long passages.

Interior Comfort & Variations

The interior of the CR 310 is where the yard’s craftsmanship is most evident. The cabin is typically finished in satin-varnished Khaya mahogany, creating a warm, traditional atmosphere that contrasts with its contemporary exterior lines. The layout is standard for a premium cruiser of this size: a V-berth forward, a central salon with twin settees, and a functional L-shaped galley to starboard.

A notable feature is the aft cabin, which provides a surprisingly large double berth for a 31-foot hull, achieved by tucking the bed under the cockpit sole. The head is located to port, often featuring a wet locker for foul weather gear—a necessary inclusion for North Sea sailing. Headroom is generous, often exceeding 1.85 meters (approx. 6'1") in the main salon, which is a significant achievement for a boat with a relatively low-profile coachroof. While the CR 310 did not have widely divergent hull variations, the yard was known for semi-custom flexibility; some units may feature different navigation station configurations or variations in the cabinetry to suit the original owner's specifications.

Known Issues & Buyer’s Checklist

When inspecting a pre-owned CR 310, buyers should focus on the following high-signal areas common to Swedish cruisers of this vintage:

  • Saildrive Diaphragm: Most CR 310s were fitted with Volvo Penta engines and saildrives. The rubber hull seal (diaphragm) should be replaced every seven years according to manufacturer recommendations. Check the date stamp on the seal.
  • Teak Deck Maintenance: If the vessel is equipped with laid teak decks, inspect for thinning wood or failing caulking. CR Yachts typically used high-quality vacuum-bonded or screwed-and-glued teak, but decades of UV exposure can lead to wear that is expensive to remediate.
  • Rudder Bearings: Check for play in the rudder post. While the steering system is robust, the bearings can wear over time, leading to a "clunking" sensation at the helm.
  • Chainplate Inspection: Ensure the stainless steel chainplates, which are glassed into the hull structure, show no signs of weeping or rust streaks, as these indicate potential water ingress into the laminate.

Community & Resources

The primary resource for technical data and historical context is the official CR Yachts website, which maintains an archive of their legacy models. Owners often find technical support and community through regional Swedish sailing associations and the broader Orust boatbuilding network, which shares many suppliers for hardware and rigging components.

The Verdict

The CR 310 is a premium pocket cruiser that offers a level of build quality rarely seen in contemporary mass-production yachts. It is an ideal choice for a couple or small family seeking a "forever boat" that is as rewarding to sail as it is comfortable to live aboard.

Pros

  • Exceptional interior joinery and material quality.
  • Stiff, balanced sailing performance with an easy-to-manage fractional rig.
  • High resale value due to the reputable Swedish pedigree.
  • Large aft berth and functional galley for extended coastal cruising.

Cons

  • Premium pricing on the secondary market compared to mass-market 30-footers.
  • Limited availability outside of Northern Europe.
  • Maintenance of teak decks (if equipped) can be labor-intensive.
