Hallberg-Rassy
HR 31
We reply within 2-3 days.
On the live Hallberg-Rassy 31 card the chips and history already name Germán Frers, years 1992-2009 and about 356 hulls - this is not an empty Nordic seed. But one year band flattens the line: the yard keeps Mk I and, from hull #307 / model year 2006, Mk II (including two spreader pairs). The overview still prints length 9.6 m, beam 3.2 m and displacement about 5400 kg, while the chips already hold 9.62 and 3.3. Until Mk II is named and the overview drops the wrong beam and the inflated displacement, you are not yet looking at the full yard sheet for this HR 31.
The model was drawn by Germán Frers for Hallberg-Rassy in Ellös. Yard sheet: hull length 9.62 m, waterline at rest 8.26 m, beam 3.30 m, standard draft 1.71 m (a shallow option 30 cm less exists), empty displacement 4500 kg, lead keel 2000 kg. The 356 hulls over 18 years are one of the yard's long runs; that is not a 120-390 fork from foreign templates. LWL is missing on the card for the antifoul calculator - the yard sheet supplies it. We do not invent an asking price.

Calculations and ratios
Brochure numbers need matching units. Open a FairHelm formula page for the classical form, rule of thumb, and limits before you compare listings.
Design history
On survey check chainplates and standing-rigging age by invoices, saildrive service, keel bolts and moisture at deck fittings - the live checklist and expert strip already point there.
Typical problems
We do not carry FAQ euro bands as SSOT (Gap); we close the flattened Mk fork and overview drift (3.2 / ~5400) to the yard sheet.
Annual ownership costs
Read kronor annual bands as a marina class around 9.6 m, not a yard offer. We do not invent an asking price.
Calculators for this boat
Indicative figure for weekend use. The country supplies berth and winter. The insurance line stays the Swedish planning band - not a Danish, German, or Dutch premium. Maintenance stays Swedish too. Not a marina quote.
- Netherlands (annual contract)€3,700 - €6,312
- Sweden (planning bands)€4,950 - €8,550
- Denmark (two harbours, season)€3,771 - €6,191
Antifouling
Litres need waterline length and draft. This page only has length overall and beam, so litres are not calculated here.

Pre-purchase survey checklist
Beside this page: the Hallberg-Rassy hub, HR 29, Monsun 31 and HR 312. Their opens are not cloned here: first fix the Mk fork and overview drift to the HR 31 yard sheet.
Expert verdict
FairHelm rating: 8.0/10: Compact HR offshore pedigree; buy on chainplates and rigging age, not cosmetic refresh alone.
