Design and Construction
What distinguishes the 485's profile is her low freeboard paired with a gentle sheerline and balanced ends — a restrained, sea-kindly silhouette that avoids the tall-sided look of many modern cruisers. The hull carries a fin-and-bulb keel drawing 7 feet standard (a 6-foot shoal option was offered), with a slightly raked rudder carried on a full skeg. At 37,550 pounds displacement with 13,000 pounds of ballast, her D/L ratio of 318 places her firmly in the heavy-displacement cruising camp, and her L/B ratio of 3.46 confirms a moderately beamy but not bloated hull. The same-mold parentage with the 461 means the fundamental hull engineering was proven before the 485 appeared, and the extension aft is what permits the layout and machinery gains described below.
Rig and Handling
The 485 is easily handled by a couple, a claim borne out by a deliberately small rig that nonetheless carries a Stoway mast for furling the main into the spar. Period reviews noted the SA/D ratio of 17.46 and the modest sail plan as a deliberate choice for manageable short-handed sailing rather than all-out performance. With 1,224 square feet of sail area, the boat is not a lightweight sprinter but a steady voyager; the skeg-hung rudder and moderate beam give her predictable manners under helm. One critique from a professional design review was the cockpit coaming, measured at about 9 inches high, which the reviewer found too low for taste, and the cockpit itself was on the small side — a trade for the protected deck saloon forward.
Accommodations
The 485 features a deck saloon with the brand's eyebrow styling and the now-classic three-cabin layout, typical for this type of boat. Her extra length over the preceding 45 and 47 models allows for a separate shower in the owner's head, a genuine comfort dividend on a boat this size, and a dedicated generator space just aft of the engine. Of the three staterooms, one is rather contracted, while the main saloon galley looks comfortable. The overall arrangement reads as a considered cruising interior where the gains from the stern extension were spent on hygiene and machinery rather than mere cabin count.
The Verdict
The Oyster 485 is a thoughtfully evolved bluewater cruiser that trades a little cockpit space and a compact third cabin for a separate owner's shower and proper generator stowage. Her Holman and Pye pedigree, proven hull mold shared with the 461, and moderate but capable rig make her a sensible choice for a couple intending serious passage work under 50 feet. The low freeboard and balanced ends give her a quiet elegance that many heavier modern designs lack.
Pros
- Proven hull lineage extended from the Oyster 461
- Separate shower in owner's head from the extra length
- Dedicated generator space aft of the engine
- Easily handled by a couple with Stoway mast and small rig
- Low freeboard with gentle sheerline and balanced ends
Cons
- Cockpit coaming about 9 inches high, judged too low by one reviewer
- Cockpit on the small side
- One of three staterooms rather contracted
