Hallberg-Rassy
HR 31
The Hallberg-Rassy 31 (Mk I and Mk II) represents the entry point into the prestigious Frers-designed era of the Orust yard. Unlike its predecessor, the 312, the HR 31 features a modern spade rudder and a more efficient underwater profile, making it a surprisingly nimble performer while retaining the brand's legendary heavy-weather security. It is positioned as a premium 'pocket' bluewater cruiser for couples who prioritize build quality and resale liquidity over the sheer internal volume offered by Mediterranean production boats.
Market context for the HR 31 is defined by its status as a 'forever boat' for many owners. In the Baltic and North Sea, these hulls trade at a significant premium compared to same-age 32-footers from mass-market brands. The buyer profile typically includes experienced sailors downsizing from larger yachts or ambitious coastal cruisers looking for Category A (Ocean) certification in a manageable size. The interior, finished in high-grade mahogany, remains a benchmark for maritime joinery in this size class.
From a surveyor's perspective, the primary focus must be the teak deck. On older units, the teak was screwed into the GRP sandwich; moisture ingress through worn bungs or failing caulking can lead to expensive core repairs. Additionally, the Volvo Penta MD2020 engine, while reliable, often shows signs of cooling system scaling or exhaust elbow corrosion after two decades. The saildrive diaphragm replacement interval (7 years) is a critical maintenance item that should be verified via invoices rather than verbal history.

Buyer FAQ
- Is the Hallberg-Rassy 31 suitable for single-handed sailing?
Yes, the HR 31 is exceptionally well-suited for solo or shorthanded use. All primary controls are accessible from the deep, protected cockpit, and the boat's predictable motion in a seaway gives the helmsperson confidence in deteriorating conditions.
- What are the main differences between the HR 31 Mk I and Mk II?
The Mk II, introduced in 2006, featured a revised deck layout, a slightly taller rig, and a more modern interior finish. However, both versions share the same hull and core engineering principles, with the Mk II commanding a higher price on the used market.
- How does the HR 31 compare to the older HR 312?
The HR 31 is a significantly better performer, especially upwind and in light air, thanks to the Germán Frers hull and spade rudder. While the 312 has a traditional long-keel feel, the 31 feels like a modern yacht while retaining the same Orust build quality.
- What should I look for regarding the engine on a used HR 31?
Most units have the Volvo Penta MD2020. Check for evidence of regular heat exchanger cleaning and verify the age of the saildrive seal. If the engine is original, expect to eventually budget for a repower or a major top-end overhaul.
- Does the HR 31 hold its value well?
Extremely well. The HR 31 is one of the most liquid models in the 30-32ft segment. A clean, documented example often sells quickly at prices that would buy a much newer 36-footer from a mass-production yard.
Design History
The HR 31 was developed as a Frers-era cruising platform for owner crews sailing Northern Europe. Germán Frers shaped the hull and deck layout for predictable manners in Baltic and North Sea conditions while keeping enough interior volume for two-berth cruising couples. Production ran from 1992 to 2009, with approximately 356 hulls built according to yard and owner-registry sources.
Hallberg-Rassy positioned the HR 31 between the classic Enderlein sub-10 m models and the larger HR 34 — explaining why well-kept examples command premium asking prices in Stockholm and Oslo marinas compared with mass-market contemporaries of the same LOA.
Mid-production updates were mostly equipment packages, interior trim, and deck hardware rather than fundamental hull changes, so survey condition and maintenance history matter more than model year alone. When you evaluate an HR 31 on Blocket, treat the maintenance story as part of the specification — not a footnote after the asking price.
Annual Ownership Costs
| Cost item | Low (SEK) | High (SEK) | Notes |
|---|---|---|---|
| Marina berth | 22,000 | 48,000 | 9.6 m class, Stockholm region |
| Insurance | 10,000 | 24,000 | Value and cruising area |
| Haul-out + winter | 14,000 | 30,000 | Yard package varies |
| Antifouling + hull care | 7,000 | 18,000 | Materials and labour |
| Engine / drivetrain | 6,000 | 18,000 | Saildrive and cooling cycles |
| Rigging reserve | 8,000 | 22,000 | Standing rigging age |
| Deck / structural reserve | 7,000 | 25,000 | Bedding and moisture follow-up |
| Total annual | 74,000 | 185,000 | Excludes major refit years |
Annual ownership for HR 31 is usually predictable when service records are complete. Berth, storage, and insurance dominate fixed costs in Sweden. The largest variables are rigging replacement timing and any survey-led deck or drivetrain work. Keep a separate technical reserve so routine season costs stay stable.
Pre-Purchase Survey Checklist
Pre-Purchase Inspection Checklist: HR 31
Hull, Keel and Underwater Body
- Moisture-map the underwater hull and document any osmosis or barrier-coat history.
- Inspect keel-to-hull joint and backing structure for movement or recurring fairing cracks.
- Check rudder bearings and steering linkage under load during sea trial.
Deck and Hardware
- Test bedding at stanchions, tracks, and winches; open nearby interior access if damp stains appear.
- Inspect hatches and portlights for seal compression and core moisture at corners.
- Verify chainplate areas internally for rust staining or soft laminate.
Rig and Sail Systems
- Confirm standing rigging age with invoices; treat unknown age as near-term replacement.
- Inspect mast step, spreaders, and terminals for corrosion or fatigue marks.
- Operate furling and reefing systems under realistic load.
Machinery and Systems
- Review engine and saildrive service including cooling, exhaust elbow, and mounts.
- Audit batteries, charging, and owner-added electrical work for safe fusing.
- Check tanks, bilges, and hoses for age-related seepage.
