Oyster 485 Review & Buyer’s Guide: The Last Human-Scale Oyster Explained
In plain terms
The Oyster 485 is a 14.8-metre British ocean cruising yacht built by Oyster Marine between 1992 and 2002. Thirty-six were made. Centre cockpit, a deck saloon crowned with the trademark Oyster “eyebrow” of wraparound glazing, a heavy solid-fibreglass hull, an external lead keel, and a rudder hung on a full skeg. The boat was conceived so that a couple could live aboard and cross oceans in comfort: three cabins, massive construction, a soft ride in a seaway. She is not a racing boat and not even a fast one — she is a floating home of the top British class, from the era when Oyster still built boats under fifty feet.
Today such a boat costs roughly €250,000 to €600,000, and almost the entire spread is explained by condition, not year. The big capital items: the teak deck, the rig, and 1990s electrics. That is what the rest of this dossier is about.
Which boat exactly: the disambiguation
Oyster has built, and still builds, many models with similar numbers, and confusion here is expensive.
- Oyster 485 (this dossier) — Holman & Pye, 1992–2002, 36 hulls, deck saloon, centre cockpit.
- Oyster 49 — a different, later boat from the Rob Humphreys era; not a sister, not a successor on the drawings.
- Oyster 475 and 495 — modern models of the reborn Oyster (the 495 dates from 2021); all they share with the 485 is the brand.
- Oyster 46 — also Humphreys, another generation entirely.
Within her own era the 485’s lineage is direct. Bob Perry, reviewing her in 2000, wrote that the 485 “evolved from the 461. It is actually built in the same mold with the stern extended.” The 485, in other words, is the summit of the Holman & Pye line of the late eighties and nineties — 435, 461, 485 — and no relation of today’s fifty-foot Oysters.
The yard: an empire, a bankruptcy, a rescue
Oyster Marine has been shorthand for British luxury cruising since 1973. But what matters to a 485 buyer is not the history of glory — it’s the history of 2018. In February of that year Oyster Marine Holdings went into administration (the administrators were appointed on 7 February): the Dutch investor HTP withdrew its support, despite a record order book in excess of £80 million and against the backdrop of the lingering insurance case over the loss of the Oyster 825 Polina Star III. By 20 March the company had been bought by the technology entrepreneur Richard Hadida, founder of Evolution Gaming, chosen from a shortlist of seven bidders. Production restarted at Wroxham in May 2018, with some fifty shipwrights rehired.
What this means for the owner of an old hull: the reborn Oyster still keeps the 485 on its Heritage pages, runs its own brokerage (Ipswich, Palma, Newport) and after-sales operations. Factory-adjacent support for a thirty-year-old boat is a rarity in this industry, and at Oyster it genuinely exists. Add a living owners’ community and the Oyster Owners’ Association — a source of manuals and hull-by-hull histories.
One thing not to carry over onto the 485: the keel of Polina Star III. That loss (July 2015, off the Spanish coast) happened to a modern 22-metre Oyster 825, and Yachting World reported the keel departed because of a hull moulding defect — explicitly not a failure of keel bolts. It has nothing to do with the Holman & Pye hulls of the nineties; Oyster called it the first and only keel failure in the yard’s history.
What kind of boat is this — if you’re seeing her for the first time
Three things define the character of the Oyster 485.
She is heavy, and deliberately so. Seventeen tonnes of displacement on 14.8 metres, a D/L ratio of about 318 — “the heavy side of medium,” in Perry’s classification. The hull is solid, uncored fibreglass; the keel is external lead, nearly six tonnes of ballast; the rudder hangs on a full skeg. Perry again: “The performance benefit of the Oyster’s displacement will be experienced in an upwind blow... the ride should be softer and far more comfortable.”
She has a small rig. The SA/D ratio is just 17.46, compounded on most boats by an in-mast furling main with no roach. Perry was honest about it: she “won’t be a light-air flyer.” Most hulls carry in-mast furling (Hood Stoway on the early boats, Selden on the later ones), some carry a conventional spar; sloop and cutter versions existed, as did a taller “sport rig” option. This isn’t catalogue fine print — it’s a real difference between individual hulls. Check what’s on the actual boat.
The deck saloon is the centre of life aboard. The trademark Oyster eyebrow, wraparound glazing, a bright saloon at deck level. Owner DickB on the YBW forum: “The deck saloon is great giving a very airy feel and in my case I have storm shutters as well.” The other side of that coin is argued below — in a hot climate, the greenhouse saloon becomes the case against.
Living with her: the people who’ve sailed one
There are fewer documented owner voices on the 485 than a boat of this class deserves — a production run of 36 does that. But the ones that exist are substantive.
“I recently purchased an Oyster 485, and am well impressed by the build quality. Massively built, medium to heavy displacement and very comfortable. Sails really well, especially windward with the cutter rig... It is quite a low freeboard and the centre cockpit is more probably shallower than the HRs or other centre cockpit yachts, still I am very pleased with the purchase. I also like the full skeg and a decent deep bilge.”
“Although the boat is ‘only’ seven feet longer than my production boat, it weighed more than twice as much... Everything was on a different scale, such as a 24-volt electrical system as opposed to 12v.”
Real ocean data. At least two 485s have crossed the Atlantic with the ARC under their own names: Barefoot, mentioned in Yachting Monthly’s rally digest among the yachts that diverted to assist another crew, and Talisman — which, per Yachting World’s ARC 2019 skippers’ survey, sailed fifteen days under a reefed main and poled-out genoa and four more under an asymmetric. The poled-out headsail balanced by a staysail worked particularly well, and the crew’s advice was to plan gybes with the pole deliberately rather than forcing the sail across. That is an honest portrait of the boat’s tradewind work: not records, but steady weeks under simple sail.
Daily runs and average speeds for specific hulls are not recorded in open sources — a direct question for owners (see Open questions).
Tropics versus high latitudes. LadyJessie (YBW, based in the Med): “I don’t like the ‘deck saloon’ types if you are sailing in warm climates. It gets very hot below. All the Oysters you see sailing in the Med have all their deck saloon windows covered up.” Owner DickB answers on the merits: the front windows open, and the low side portlights pull cool air off the water. The argument — a blood relative of the doghouse debate around the Boréal 44 — is unresolved, and the buyer must resolve it against their own route.
The great debate: what the Oyster premium actually buys
The central conflict around the 485 is not technical — it’s about money: whether the boat is worth its reputation. The argument is on the record in the well-known YBW thread “Why are Oyster Yachts so expensive?” (2010) and around it.
He called the Oyster he inspected one of the most gorgeous and most gorgeously engineered yachts he had ever seen — “certainly worth three Jeanneaus.”
Against — tcm, same forum: the fitout is “ok but not in the least bit mindblowing — same switchgear in the saloon as a beneteau, non-marine quality screws around the companionway.” asteven221: “Lovely boats, better joinery, but that’s about it.”
And a second layer of the same argument — resale value:
“I would not agree that Oysters are cheaper SH compared to HR. When I was in the market there were both available two of each HR 46 and 2 x 485’s. The Oysters were more expensive considering the levels of equipment... It is my opinion that Oysters are generally more expensive both new and SH.”
LadyJessie, same thread: “HR’s tend to hold their values better than Oysters. New Oysters tend to be more expensive than an HR of similar size, but in the second hand market it is the other way around.”
Two owners, one market, opposite observations — logged and left open.
The most practical contribution to the debate came from Dockhead himself, explaining why “reasonable” used-Oyster prices deceive: “I thought I could get a decent 485 less than 10 years old for less than 300k GBP, but it turned out that all those on sale had been run back and forth across the Atlantic, had been very heavily used and depleted... they were all knackered... the average 10-year old Oyster has got 3x or 5x the miles on it than the average 10-year old anything else and so the apparently reasonable price is deceptive.” That is the key to this entire market: a 485’s price is a function of biography, not of year.
Buying a used Oyster 485: what to check
From here on, this dossier switches to survey mode. Print this section and take it to the boat.
The teak deck: item number one
These decks are now 24 to 34 years old, and they are the market’s great divider. A prospective buyer, “Julie”, on a specific boat (Sawmill Creek forum): “The boat is rock solid. Below decks it is practically perfect... But the teak decks are in their last days and that’s probably why this boat hasn’t sold. The broker thought so.” The remedy is expensive: the owner of a fifty-foot Oyster on SailNet was quoted “over $2K/foot of boat” for a replacement. And the fastening method varies by hull — its own fork in the road: some descriptions speak of screwed-and-bunged planking, yet one documented 1995 boat (Tradition, Ensenada) has her teak “epoxied down (not screwed).” Whether that is original spec or a later re-deck is not recorded. At survey: establish the fastening method, moisture in the deck beneath, the state of bungs and seams — and do the honest arithmetic: a deck “in its last days” equals a six-figure line item, or a conversion to synthetic teak or painted non-skid.
The Hood Stoway in-mast furler
The richest documented problem area on the boat. Owner tudorsailor (YBW, thread “Do you have Hood Stoway electric in-mast furling?”, 2012–2019) chronicled a years-long saga: phantom trip alarms (“sometimes it happens while sailing. Sometimes in the middle of the night in the marina”), a motor burnt out after a delivery crew fiddled with the trip settings, a motor that is “hidden within the mast and impossible to check,” and the dark art of jam-free furling — boom at about eight degrees, so the sail furls “with a nice helix at the foot.” His eventual fix, in 2019: an external voltage dropper feeding the control box 12 volts instead of 24. His standing advice: carry the adapter that lets you furl with an electric drill should the motor fail. At survey: a demonstration of furling under load, the motor’s age, and the presence of that emergency drive.
Keel and keel bolts
The keel is external lead, a fin with a bulb, close to six tonnes. The bolt material is not documented in any primary source — the only claims come from an AI aggregator that contradicts itself, and we do not use them. At survey: the keel-to-hull joint (any “smile,” any weeping), a torque check, and a written statement from the surveyor on bolt material and condition.
Hull and osmosis
Solid, uncored fibreglass — confirmed by the listings of specific boats. Not a single documented case of osmosis on a 485 or her sisters (461, 475, 55) was found — but neither is there positive evidence of a clean fleet. Moisture readings are mandatory; the history of any epoxy treatment goes on the list of questions for the seller.
Engine
Early hulls carry the Perkins M90 (82 hp), later ones a Yanmar 4JH-series (88 hp); the exact changeover year is not documented. The Yanmar is easier for parts and service today. Check: hours, heat exchanger, anodes, generator hours.
Electrics and 1990s systems
A 24-volt network, now 25-plus years old. The experience of the neighbouring model applies (zendog, Oyster 435 owner, YBW): “After 20 years and many modifications and additions from the 3 owners, the electrics are becoming rather convoluted and threading additional wiring behind the woodwork is not easy.” A boat with no documented electrical and electronics refresh after roughly 2015 is its own budget line.
Field notes from the Zingaro refit
James of Sailing Zingaro, who bought a 1993 hull after a long lay-up, replaced the rudder bearings and bushings (“It was a huge job”) and all sixteen thru-hulls. That is the map of an aged 485’s weak points after neglectful ownership: rudder, seacocks, window seals.
Price and market: don’t believe the “28 for sale”
The 485’s market contains a trap worth naming outright. Aggregators running on the Boats Group engine — YachtWorld, boats.com, Boatshop24 and others — display “28 Oyster 485” in their headers. It is an artefact: the pages themselves say no matching listings were found and show “listings we think you might like,” and among those 28 sit Oyster 49s, 46s, 54s, 56s, 435s and even a stray Island Packet 485. The real number of unique 485s for sale at any moment is a handful — on the order of three to eight boats worldwide. For a 36-hull production run, that is normal.
The observed asking range across 2024–2026 listings: from $295,000 (Pemaquid, 1998, Georgia, USA — a turn-key boat, but with teak on its last legs) to €590,000 for a deeply refitted example in Palma; in between, $410,000 for a 1995 hull with a 2023 refit and glued teak (Ensenada), €245,000 for a 1997/98 boat in Greece, £440,000 with a price cut in Barcelona. The multiple “Price Drop” flags across the market signal soft pricing and room to negotiate.
The boat’s original price in pounds, 1992–2002, is not documented anywhere we could find — an open question.
The practical conclusion is the mirror image of the Boréal 44: there, the boats barely exist for sale; here, the boats exist, but nearly every one is a veteran with a long biography. Dockhead’s formula works as a filter: the average Oyster carries several times the market-average mileage, so a cheap 485 is not a find — it is a prompt to price the refit. The premium for a documented recent refit — teak, rig, electronics — is the best-justified money on this market.

Oyster 485 vs Hallberg-Rassy, Amel and Discovery
Hallberg-Rassy 46/48 is the principal rival, and the only one with a rich documented argument behind it. mocruising cross-shopped the 485 against the HR 46 and 49 — and chose the HR 46, glad he skipped the 49: “the sailing performance is not a patch on the newer designed 46 G Frers.” His observation stands: the Oysters were more expensive at comparable equipment levels. LadyJessie adds the climate argument (the hot deck saloon) and a resale claim that directly contradicts mocruising’s (see the debate above). In sum: the HR offers a hard windscreen instead of an observatory saloon, Swedish systems engineering, and a more liquid market; the 485 offers more light and volume in the saloon and more British joinery.
Amel Super Maramu 2000 is the French answer to the same question — a boat for a couple to sail around the world: a ketch, a fully enclosed cockpit, everything electric and everything proprietary. The philosophical contrast with the 485 could not be starker: the Amel is an integrated system in which the yard decided everything for you; the Oyster is a classic yacht you equip and maintain yourself. The SM2000’s market is an order of magnitude livelier — some 500 hulls against 36. Live dossier: Amel Super Maramu 2000.
Discovery 55 is the direct classmate in the British deck-saloon genre; the forums regularly place it in the same basket (“I would add a Discovery 55 to your list... perfect boats to take around the world” — Cruisers Forum). Bigger, younger, dearer.
Oyster 53/56 is the in-brand step up: the same philosophy, more volume, more budget.
Comparable Swans get cross-shopped on pedigree, but no documented head-to-head of the 485 against a Swan 46 or 48 was found; typologically these are different boats — the Swan a performance cruiser with a racing bloodline, the 485 a floating home. Live dossier for the Swan 46.
Open questions
This dossier doesn’t pretend to omniscience. No magazine test of the 485 was found — neither a new-boat test (Yachting Monthly, Yachting World, PBO, SAIL, Cruising World, YACHT.de, Sailing Today, 1992–2002) nor a later used-boat feature; the only substantive independent review is Bob Perry’s from 2000. The keel bolt material is unconfirmed by primary sources. The fleet’s osmosis history is absent in both directions. The deck core material is undocumented. The timeline of the Perkins-to-Yanmar changeover and of the teak fastening method by year is not established. The original price in pounds has not surfaced. The Atlantic crossing times of the named ARC boats (Barefoot, Talisman) have not been extracted from the rally archives. Two directly relevant Cruisers Forum threads — “Oyster 485, 49, 49PH, and 53” and “Oyster 435-485 range — any bad models?” — are blocked to access, and their contents remain a blind spot. Claims circulating on AI aggregators (a Yachting Monthly “modern classic” retrospective, “numerous Oyster World Rally circumnavigations,” mild-steel keel bolts) are unverified and are not used in this dossier. Owners’ answers will appear in the next revision.

FAQ
How much does a used Oyster 485 cost?
From about $295,000 for a working boat with tired teak to about €590,000 for a deeply refitted example. The middle of the market sits at €400,000–500,000. Only a handful are for sale at any moment; the “28 listings” figure on aggregators is a technical artefact.
What are the known problems of the Oyster 485?
Age-related, not structural: teak decks at the end of their life (replacement runs over $2,000 per foot), the temperamental Hood Stoway electric furler (phantom alarms, a hidden motor), 1990s electrics and electronics, and worn rudder bearings and seacocks on boats that have sat idle. No systemic structural defects, osmosis epidemics or model recalls are documented.
Oyster 485 or Hallberg-Rassy 46?
Owners who chose between them disagree. For the HR: the sailing qualities of the Frers design, a hard windscreen with no greenhouse effect, and — contested — better resale. For the 485: the light and volume of the deck saloon, British joinery, the full skeg. Both are established ocean classics; the route and the individual hull decide.
Is the Oyster 485 suitable for the tropics?
Contested — the same conflict as every deck saloon. Critics: it gets very hot below, and the Oysters in the Med sail with their saloon windows covered. A 485 owner answers: the front windows open and the low portlights pull cool air off the water. Unresolved; for a tradewind route, look also at the Amel Super Maramu.
How many Oyster 485s were built?
Thirty-six hulls over ten years (1992–2002), per Oyster’s official Heritage page. The figure of 35 that circulates — including from the owner of Zingaro II — is preserved as a contradiction.
What happened to Oyster in 2018, and does it matter to an owner?
The yard went into administration (February 2018) and was bought by Richard Hadida (March 2018); production restarted within two months. Today Oyster supports its old hulls through its own brokerage and service operations — for a 485 owner, the story ended well.
Verdict
The essence in one paragraph: the Oyster 485 is the last human-scale Oyster, the summit of the Holman & Pye era, built thirty-six times for couples who went to sea in earnest. Structurally the boat is sound: a solid hull, a lead keel, a skeg — thirty years on, the fleet has accumulated no case against the drawings. Everything that can go wrong is written not in the plans but in the logbook of the individual hull: the teak, the motor in the mast, the electrics, the miles. Buying a 485 is one quarter choosing a model and three quarters choosing a biography.
Method: this dossier was assembled from the yard’s own documentation (Oyster Heritage), Bob Perry’s design review (Sailing, 2000), owner threads on YBW and Cruisers Forum, ARC skippers’ surveys (Yachting World, Yachting Monthly), the Sailing Zingaro refit record, and brokerage archives 2024–2026. Quotes are reproduced verbatim or translated with meaning preserved. Where sources disagree, we either resolved the conflict with data or left it honestly open. Claims traceable only to AI-generated aggregators were excluded. Owner interviews are underway; their testimony will join the next revision.
