The Oyster 485 belongs squarely to Holman and Pye’s line of cruising designs for Oyster Marine. Conceived as a serious bluewater cruiser under 50 feet, the 48foot6inch yacht evolved directly from the Oyster 461. It was built in the same mold, with the stern extended to provide the additional length.

Only thirty-six examples were delivered during a ten-year production run from 1992 to 2002. Its measured evolution, rather than a clean-sheet redesign, says much about the boat’s character: this is a typical Holman and Pye design, conservative in proportion and purposeful in function.

Design and Construction

The 485’s profile is distinguished by low freeboard, a gentle sheerline, and balanced ends. The result is a restrained, sea-kindly silhouette that avoids the tall-sided appearance of many modern cruisers.

The hull has a fin-and-bulb keel with a standard draft of 7 feet; a 6-foot shoal-draft option was also offered. A slightly raked rudder is carried on a full skeg. Displacement is 37,550 pounds, including 13,000 pounds of ballast. A D/L ratio of 318 places the 485 firmly among heavy-displacement cruising boats, while its L/B ratio of 3.46 indicates a moderately beamy but not bloated hull.

Because the 485 shared its mold with the earlier 461, the fundamental hull engineering had already been proven before the newer model appeared. The extension aft made possible the accommodation and machinery improvements described below.

Rig and Handling

The 485 was designed to be easily handled by a couple. Its deliberately small rig includes a Stoway mast, with the mainsail furling into the spar. Period reviews cited the SA/D ratio of 17.46 and described 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 485 is not a lightweight sprinter but a steady voyager. Its skeg-hung rudder and moderate beam give it predictable manners under the helm.

The cockpit does involve some compromises. A professional design review measured the coaming at about 9 inches high, which the reviewer considered too low. The cockpit itself is also on the small side—a trade-off for the protected deck saloon forward.

Accommodations

The 485 has a deck saloon with Oyster’s eyebrow styling and the now-classic three-cabin layout, typical of this kind of boat. Compared with the preceding 45 and 47 models, its extra length provides a separate shower in the owner’s head—a genuine comfort benefit on a boat of this size—as well as dedicated generator space just aft of the engine.

Of the three staterooms, one is rather contracted, while the main-saloon galley appears comfortable. Overall, the interior is thoughtfully arranged for cruising. The gains from the stern extension went toward better washing facilities and machinery space rather than simply increasing the cabin count.

Verdict

The Oyster 485 is a thoughtfully evolved bluewater cruiser. It trades some cockpit space and a compact third cabin for a separate shower in the owner’s head and proper generator stowage. Its Holman and Pye pedigree, proven hull mold shared with the 461, and moderate but capable rig make it a sensible choice for a couple planning serious passage work in a boat under 50 feet. Low freeboard and balanced ends also give it a quiet elegance that many heavier modern designs lack.

Pros

  • Proven hull lineage extending from the Oyster 461
  • Separate shower in the owner’s head, made possible by the extra length
  • Dedicated generator space aft of the engine
  • Small rig and Stoway mast designed for easy handling by a couple
  • Low freeboard, gentle sheerline, and balanced ends

Cons

  • Cockpit coaming measures about 9 inches high and was judged too low by one reviewer
  • Cockpit is on the small side
  • One of the three staterooms is rather contracted
