Oyster 675 Information, Review, Specs

Sailing Performance & Handling

The Oyster 675 is engineered for high-latitude exploration and rapid ocean crossings. Unlike the heavier displacement Oysters of the 1990s, the 675 utilizes a modern hull form with twin rudders, which significantly enhances control when the boat is heeled, particularly in heavy weather. According to editorial testing by Yachting World, the twin rudder configuration provides exceptional grip, allowing the yacht to track straight even in gusty conditions that would cause a single-rudder boat to round up.

The standard sail plan is designed for ease of handling, featuring an in-mast furling mainsail and a blade jib. However, many 675s were specified with a carbon fiber mast and performance sails to capitalize on the hull’s inherent speed. The Sail Area to Displacement ratio (SA/Disp) is generous for a bluewater cruiser, ensuring that the 675 remains lively in light airs. Handling is further simplified by the "button-push" nature of its hydraulic systems, which manage the primary winches and furling gear from the safety of the twin-helm cockpit.

Interior Comfort & Variations

The interior of the Oyster 675 is defined by its "Seascape" windows—long, horizontal hull ports that offer panoramic views of the water while seated in the saloon. This feature drastically reduces the "basement" feel often associated with large center-cockpit yachts. The standard configuration typically features an expansive owner’s suite aft, which is a hallmark of the Oyster brand, providing a private sanctuary with a dedicated desk, sofa, and en-suite head.

Variations on the same hull focus primarily on cabin count and crew arrangements. While most owners opt for a three or four-cabin layout with a large galley in the starboard passageway, some hulls were customized to include a dedicated crew cabin forward or a more open-plan saloon. The choice of timbers—ranging from traditional teak to contemporary limed oak or American walnut—further alters the onboard ambiance. The 675 shares much of its design DNA with its larger sibling, the Oyster 745, which was developed concurrently to ensure a consistent design language across the larger models in the range.

Popular Mentions & Media

The Oyster 675 has been a frequent participant in the Oyster World Rally, a prestigious circumnavigation event organized by the builder. Its capabilities were highlighted when the first hull, Babiana, underwent extensive sea trials and media presentations, showcasing the model's ability to maintain high average speeds over long distances. The model has also been featured in technical segments by Sail Magazine, focusing on its integration of complex hydraulic and electrical systems into a user-friendly interface.

Known Issues & Buyer’s Checklist

Prospective buyers of an Oyster 675 should approach the survey with a focus on the yacht’s sophisticated mechanical systems.

• Hydraulic Systems: The 675 relies heavily on a centralized hydraulic power pack for sail handling and thrusters. Service records should be scrutinized to ensure the fluid and filters have been changed regularly and that there are no leaks in the high-pressure lines.
• Deck Hardware: Given the high loads generated by the 675's rig, the mounting points for the primary winches and the condition of the captive winch systems (if fitted) should be inspected for stress fractures or excessive wear.
• Teak Deck Condition: Oyster uses high-quality teak, but at this size, the cost of replacement is significant. Buyers should check for thinning or "proud" caulking, particularly in high-traffic areas around the helm and companionway.
• Electronics Integration: The 675 utilizes a complex digital switching system. Ensure that the software has been updated and that the interface between the navigation instruments and the yacht's power management system is functioning without "ghost" errors.

Community & Resources

Owners of the 675 benefit from the Oyster Owners' Association, a robust network that provides technical support, organized regattas, and a dedicated concierge service for global cruising. This community is a primary source for technical wikis and shared knowledge regarding model-specific maintenance.
