Frers drew a hull with an almost full-length waterline — 10.1 metres at rest, a full metre more than the 342 — beam carried well aft, and a straight stem with an integrated bowsprit. From the dock, the effect is unmistakably contemporary. But Hallberg-Rassy retained its rubbing strake, generous teak coaming, and trace of sheer, threading enough continuity that the 340 still reads as a Rassy rather than a fashion statement. She carries CE Category A certification for unlimited ocean voyages and displaces just under six tonnes — heavier than many performance cruisers of similar length, a deliberate choice that pays dividends in a seaway.
Hull, Construction, and Sea Manners
The 340's hull and deck use Divinycell foam coring throughout, providing stiffness and thermal insulation without the moisture risks associated with balsa. A structural grid is laminated into the hull bottom, a substantial ring frame distributes mast loads, and the laminate schedule relies on woven rovings — long filament runs that resist moisture uptake and make osmotic blistering unlikely. The rudder shafts are solid stainless steel. The level of finish is immediately apparent on deck: flush surfaces, a generous toerail, and teak grabrails on the coachroof. As one reviewer put it, the split shroud base, which gives almost unimpeded passage along the sidedecks, solves a problem that hadn't been noticed until it disappeared.
In a seaway the 340 behaves with composure that belies her sporty appearance. During an early trial in the Øresund, a 30-knot squall pinned the crew in a shipping channel. Rather than rounding up, the boat feathered the wind at 25–30° apparent and held steerage at 3 knots while a reef went in — the kind of controlled response that inspires lasting confidence. She does not have the deep forefoot of a traditional offshore cruiser, and her rounded underwater body means she does not slam like some flat-floored performance designs, though she also does not slice through chop with the authority of a deep-vee hull.
Rig and Sailing Performance
The fractional rig is the centre of the 340's character. The headsail has a small overlap — enough to drive well upwind, simple enough to tack without drama — and self-tacking is an option. Cap shrouds and lowers are separated with individual chainplates, giving easy deck passage and a wide, steady mast base. An under-deck Furlex TD furler keeps the foredeck uncluttered, and a backstay tensioner with a 1:32 purchase is standard, giving real control over forestay tension. According to Frers's own speed diagram, a loaded 340 will make 7.31 knots at 90° true wind angle in just 10 knots of breeze — numbers that the sea trials support in practice.
In a six-day Baltic cruise covering 300 miles, three passages of over 80 miles averaged 5.5–6 knots, and on a close reach in flat water the boat made nearly 6 knots in under 6 knots of apparent wind under code zero and full main. The long waterline pays upwind dividends: in 15 knots apparent wind the boat logged 6.4 knots just off close-hauled with a finger-light helm. Off the wind the picture is more nuanced. The modest genoa contributes little downwind drive, making a code zero or asymmetric essential for reaching and running. Crew comfortable with sail changes will find the transitions reasonably controlled with the furling gear; those less eager for foredeck work may find the process demanding.
Cockpit and Deck Handling
The cockpit extends all the way to the transom, making it one of the most spacious on any 34-footer — at 2.83 metres it is 42 centimetres longer than the 342's. Two winches per coaming handle sail trim, and halyards run in concealed channels back to the cockpit, keeping sidedecks and the working area uncluttered. A large starboard locker swallows dinghy, outboard, liferaft, and fenders. The windscreen converts quickly to a full spray hood, and the surface beside the companionway doubles as a useful navigation workstation.
Twin wheels are the popular choice, though they come with tradeoffs on a boat of this size. The 48:1 backstay purchase sits directly between the two wheels and can obstruct movement when fully deployed. The helm position lacks foot blocks, growing uncomfortable when heeled on long watches; after extended periods many helmspeople resort to the autopilot. Anyone who values active helming might seriously consider the tiller option, which is the factory default for good reason. The bowsprit, fixed rather than retractable, is excellent for code zeros and anchor work but adds anxiety in marina manoeuvring, and the split pulpit — necessary for sail handling beyond the forestay — leaves foredeck crew feeling exposed in rough conditions.
Accommodations and Interior
Below the companionway the 340 feels markedly more traditional than its deck promises. High-quality woodwork and Nordic craftsmanship set the tone. The saloon is bright — two overhead hatches, large portlights in the coachroof, and hull windows — with standing headroom of 1.90 metres. Settees run to 2.00 metres and sit further aft than is typical, giving the saloon unusual width and volume, and the mast is positioned aft of the main bulkhead so it does not interrupt the space.
The forward vee-berth is 2.04 metres long and 1.98 metres across at its widest — genuinely generous for the size. The aft cabin offers another large double, well-separated from the saloon, with access to the steering gear and the back of the engine. A heads compartment, wet locker with dual-function door, and hanging lockers complete the arrangement.
The galley is aft-facing and compact, intentionally positioned out of the main traffic flow. It is well-appointed — deep double sinks, a large fridge, Corian worktop as standard — but tight when the boat is heeled on port tack, where gravity pushes the cook toward the hob and makes simultaneous use of sink and stove difficult. The omission of a dedicated nav station keeps the saloon open and airy but leaves the saloon table as the only chart or laptop workspace. Storage throughout requires creative thinking: the hull portlights that contribute so much to the light-filled feel occupy space that would otherwise be lockers, and tanks consume most of the underfloor volume.
Hallberg-Rassy subsequently introduced a second interior configuration, Edition Two, which trades the standard twin-cabin layout for a single forward cabin. The changes are substantial: the forward berth grows from 58 to 98 centimetres at its narrow end, the heads floor area more than doubles with a separate shower, and the cockpit locker volume doubles — a significant reorganisation that suits owners who cruise as a couple rather than with guests.
Known Issues and Surveyor Notes
The 340's relatively short production history means few boats have accumulated the mileage needed to reveal systemic structural faults, and the woven-roving laminate schedule is not prone to osmotic problems. Surveyors familiar with the brand flag a handful of areas worth monitoring. The saildrive O-ring seal should be replaced every seven years — straightforward maintenance, but easy to overlook on a low-hours boat with no service history. Seacocks older than five years are worth replacing at survey regardless of apparent condition. On earlier hulls built with teak decks rather than Eco Deck, teak wear around fittings and deck lockers deserves careful examination, since not all owners maintain it to the standard the material demands. The Volvo Penta D1-30 is a reliable unit when serviced consistently; the oil filter requires access through a locker cut-out under the sink, which is inconvenient enough to discourage irregular service intervals. Twin rudders produce a small quirk under power: a burst of forward thrust sends water between rather than directly over the blades, delaying the onset of steerage — noticeable in tight quarters, though easily managed with practice.
The Verdict
The Hallberg-Rassy 340 occupies a specific and well-defined niche. She is not the most storage-efficient 34-footer available, nor the fastest, nor the most ocean-ready in terms of stowage and self-sufficiency. What she is, with considerable conviction, is a lively and rewarding coastal and bluewater cruiser that blends genuine performance with the build quality and sea manners of a boat designed to last decades. The Sailing Today test described her as "a revelation" and "totally in control"; Yachting World called her "a very well designed and finished cruising yacht." Cruising World named her Best Midsize Cruiser Under 40 feet. These assessments converge on the same conclusion: the 340 delivers more sailing pleasure per metre than almost anything else at this length.
