Interior Accommodations

This Oyster 485 features the sought-after three-stateroom layout with a passageway galley and richly finished teak interior. Designed for serious bluewater cruising, this configuration offers superb liveaboard comfort, excellent sea-keeping, and thoughtful separation of living and private spaces.

The raised deck saloon delivers panoramic views and abundant natural light through wraparound coachroof windows. To port, a large U-shaped settee surrounds a solid teak dining table (with hidden leaf), comfortably seating six. To starboard, a double settee. A full-sized, forward-facing navigation station is located aft to port, with dedicated space for instruments, communications, and charts—ideal for passage making.

Forward of the saloon, two guest cabins provide accommodation for four. The forepeak cabin features a V-berth with lockers, drawers, and overhead storage. To port is a twin cabin with upper and lower bunks, hanging locker, and reading lights. These two cabins share the forward head, equipped with a marine toilet, wash basin, and shower.

The passageway galley runs aft to starboard, offering excellent safety at sea with secure handholds and deep counters. Galley dimensions are generous, with counter ample counter space. Amenities include a gimballed four burner stove and oven, twin stainless sinks, top loading freezer and front-loading refrigeration, microwave, and extensive locker and dry storage—everything needed for extended cruising.

The aft owner’s stateroom spans the full beam and is a highlight of the design. It includes a centerline queen berth with side access, lockers, numerous drawers and shelves, and an en suite head with a separate shower stall. Ventilation is excellent via multiple opening ports and hatches, and there is ample natural light throughout the space.

The teak joinery is hand-finished and accented by solid trim and subtle lighting. Every detail reflects Oyster’s renowned build quality and attention to offshore practicality, including integrated handholds, secure sea berths, and easily accessible systems.

This well-conceived interior combines traditional elegance, modern comfort, and proven offshore functionality—making the Oyster 485 a top-tier choice for serious cruisers and world voyagers.

Deck and Hull

The Oyster 485 features a powerful yet manageable deck layout designed for safe and efficient offshore sailing with a shorthanded crew. Her wide side decks, aluminum toe rail, and solid stainless steel handrails provide secure movement around the boat in all conditions.

The furling headsail and slab-reefed mainsail contribute to easy handling on long passages or when coastal cruising. The deck includes ample storage in sail lockers and lazarettes.

Deck hatches and opening portlights provide robust ventilation and light below. Teak decking on the coachroof and cockpit sole and side decks adds sure footing. The anchoring system includes a powerful windlass, oversized anchor, and large bow roller assembly with chain locker access via a forward deck hatch.

The Oyster 485’s center cockpit is deep, secure, and exceptionally well protected—ideal for passagemaking in bluewater conditions. High coamings, wide seats, and a full cockpit enclosure (dodger and bimini) create a safe and comfortable command center for extended time at sea or socializing at anchor.

A single helm station with a large folding wheel provides excellent visibility forward over the raised saloon coachroof. The pedestal is equipped with sailing instruments, autopilot, and radar/chartplotter, with repeaters mounted under the dodger.

Cockpit dimensions are generous enough to accommodate guests for outdoor dining, with a folding teak table mounted on the pedestal as well as collapsable main helm steering wheel. Access to the wide stern platform and swim ladder makes boarding from a dinghy or swimming off the boat simple and safe. The dingy is stowed safely out of the way on Kato folding davits.
