Hull Form and Construction
The 310 broke from the yard's own lineage with a hull Frers conceived from the keel up. She is shorter overall but longer on the waterline than her predecessor, a trade that pays dividends at every point of sail. The entry is fine, the bow hollow before filling out to maximum beam at the companionway, creating a shape that slips cleanly upwind while carrying enough volume forward to keep the foredeck manageable. Below the waterline, sections forward of the lead fin keel are rounded for smoother upwind performance, and the run flattens aft.
Construction follows a well-proven formula. The hull is hand-laid GRP with a closed-cell Divinycell core above the waterline and solid laminate below; the deck is similarly cored except in load-bearing areas. Crucially, hull and deck are laminated together before the interior is fitted, giving what the yard describes as an unbeatable torsional strength factor. The lead keel is secured with nine M20 stainless steel bolts to the keel stub, and a steel beam runs from the mast base down to the stiffening grid beneath the cabin sole.
Rig, Sailplan, and Handling
Seldén supplies the fractional, deck-stepped mast carrying two sets of sweptback spreaders with separated upper and lower chainplates, a layout that keeps the side-deck clear and allows the non-overlapping jib to sheet cleanly. A recessed Furlex under-deck furler is standard. The split backstay carries a 24:1 tensioning system, and the mainsheet runs 6:1 on a cockpit-wide 4:1 traveller, so rig and sail trim stay firmly in the helmsman's hands from the cockpit.
The proof came in testing. Reaching in 22 to 27 knots of apparent wind, the boat made 7.2 to 8.7 knots, and the Yachting Monthly crew found main and jib easily managed in conditions that proved quite something to handle. She feels gloriously responsive, easily controlled and well weighted at the helm. One caveat the Yachting Monthly test surfaced: pushed past about 30 degrees of heel on a dead run in building waves, the rudder loses grip and she broaches — though stiffness makes the event less dramatic than it would be aboard most other 31-footers. Her ballast ratio of 38.6 percent is the highest among contemporary 31-footers tested at the time, which is the structural reason she recovers composedly.
Optionally, a Code Zero or gennaker can be set between the masthead and a removable bowsprit using stainless fittings to port, extending the light-air wardrobe without cluttering the working deck.
Accommodations and Interior Layout
Hallberg-Rassy made a deliberate and controversial choice with the 310's interior: no chart table. Magnus Rassy's research showed coastal cruisers rarely conduct serious paper chartwork, and the space freed up is put to immediate use. The galley was turned 90 degrees to open the saloon corner; the heads were moved forward to maximize the main living area. The result is a saloon 10 centimeters longer than the 342's, with the same table as the 372 — a 37-footer. Headroom throughout the saloon is 1.87 meters, and the mast support sits at the main bulkhead rather than intruding into the living space.
Fourteen light inlets total — four skylights, two in the saloon, plus nine opening portlights — give the below-decks an almost improbable brightness for a 31-footer. Norwegian magazine Seilmagasinet called the galley placement a stroke of genius: angled below the cockpit for full stowage depth without the claustrophobic feeling typical of boats this size.
The aft cabin offers a berth 206 centimeters long and 143 centimeters in the wide end, with two opening portlights and a hanging locker. Forward, the forecabin carries its own vanity and hanging locker and benefits from good ventilation. Yachting Monthly noted the forecabin door has no upper frame, which compromises privacy somewhat, and the heads — adequate for a 31-footer — feels comparatively confined set against the expansive saloon. The toilet compartment gains a frosted-glass skylight, but reviewers noted no bracket for a showerhead, no towel hook, and no toilet-roll holder as small finishing oversights.
Known Issues and Practical Considerations
The Yachting Monthly 24-hour test, conducted in demanding autumn conditions, surfaced a handful of practical notes. The aft cabin mattress would benefit from being two-piece rather than one to allow access to systems stowed under the berth. At the bow, there is no fairlead between the bow roller — offset to starboard — and the cleats, meaning a windlass installation would need to include a deck-mounted fairlead. With the traveller eased in off-wind conditions, the mainsheet can drape over the cockpit coaming's gelcoat and flatten the aft end of the sprayhood — a cosmetic and minor practical irritant.
The raw water filter is the one awkward access point in an otherwise well-engineered engine space; everything else, including the keel bolts and transducers visible through panels in the sole, is accessible without drama.
Refitting and Upgrading
The 310 was designed to accept upgrades gracefully. The removable bowsprit fitting means a Code Zero or gennaker can be added without structural modification. The CAN bus wiring system supports the saloon's dimmable lighting circuits and offers a logical foundation for electronics expansion. Because the top and lower shroud chainplates are separated at individual deck fittings, changing standing rigging does not require disturbing adjacent deck hardware.
Owners seeking shallow-draft access to restricted anchorages can specify the 25-centimeter shallower draft variant available from the factory, though this comes at a small cost to ultimate stiffness. The 115-amp alternator and 200-liter fresh water tank are starting points rather than ceilings; both are commonly upgraded by owners outfitting the boat for extended passages.
The Verdict
The Hallberg-Rassy 310 is what happens when a serious offshore yard commits fully to the idea that a 31-footer should live up to the same standard as its 50-footer. Frers gave the hull genuine speed and stiffness; the interior team gave it a saloon that embarrasses many 37-footers; the yard gave it construction quality that makes the word "bulletproof" feel undercooked. She is not cheap, and she is not simple — but she asks little of her crew and gives back a great deal in return. As Båtnytt summarized: the discerning customer who can pay the price gets a complete yacht.
Pros
- Highest ballast ratio in class produces composure in heavy air with far less drama than rivals
- Saloon dimensions equal to Hallberg-Rassy's own 37-footer; exceptional light and ventilation below
- Clean, uncluttered deck with all controls aft and separated chainplates for safe side-deck passage
- CE Category A (unlimited ocean) certification in a 31-foot platform
- 132-unit production run across 15 years reflects genuine long-term owner satisfaction
Cons
- No fairlead from bow roller to cleats; windlass installation requires additional deck hardware
- Forecabin door lacks an upper frame, reducing privacy in the forward cabin
- Heads feel tight relative to the saloon and is short on basic fittings
- Rudder grip diminishes past roughly 30 degrees of heel on a dead run in steep seas
- No chart table is a deliberate design choice that still divides opinion among offshore purists
