The Cheoy Lee Offshore 53 MS (Motorsailer) represents a pinnacle of the "heavy cruiser" era, emerging from a collaboration between the legendary Robert Perry and the prolific Lo family of Cheoy Lee Shipyard. Introduced in the late 1970s and produced into the 1980s, this vessel was designed to bridge the gap between a pure sailing yacht and a long-range trawler. Built on a hull shared with the Offshore 53 sailing version, the "MS" variant is distinguished by its substantial deckhouse, dual helm stations, and a significantly larger engine package, typically featuring power plants in the 120hp to 200hp range. It was engineered for the owner who prioritizes climate-controlled passage-making and the ability to maintain hull speed regardless of wind direction, all while retaining the steadying influence and redundancy of a ketch rig.

Sailing Performance & Handling
The Offshore 53 MS is a high-displacement vessel that prioritizes sea-kindliness over raw speed in light air. With a displacement-to-length ratio that firmly places it in the "heavy" category, the hull is designed to "punch through" rather than ride over chop, providing a stable platform in blue-water conditions. According to the design philosophy of Robert H. Perry, who penned the lines for several iconic Cheoy Lee models, the boat features a long fin keel and a protected skeg-hung rudder, ensuring excellent tracking during long-distance passages.
Under sail, the ketch rig provides a versatile sail plan that is easily managed by a couple. The "jib and jigger" configuration (using the headsail and the mizzen) is particularly effective for balancing the boat in heavy weather or while motorsailing to dampen roll. While it will never be a "pointer" in an upwind race—due to the windage of the large pilothouse—the boat excels on a reach. In conditions where a lighter boat might be overwhelmed, the 53 MS remains composed. When the wind dies, the vessel's identity as a motorsailer becomes its greatest asset; the large fuel capacity and robust engine allow for transoceanic range under power alone, a feature rarely found in pure sailing hulls of this size.
Interior Comfort & Variations
The interior of the Offshore 53 MS is a testament to Cheoy Lee’s legacy of joinery, characterized by an abundance of hand-finished teak and a layout that emphasizes long-term liveability. The central feature is the raised pilothouse, which provides 360-degree visibility from an internal steering station—a critical feature for voyaging in high latitudes or inclement weather. This "deck saloon" arrangement allows the galley and social areas to remain integrated with the view outside, preventing the "basement" feel common in traditional deep-keel sailboats.
The vessel was typically configured in a three-stateroom layout. The "Great Cabin" aft is a hallmark of the Perry design, often featuring a centerline queen berth, extensive hanging lockers, and a private head with a dedicated stall shower. Forward of the salon, the layout usually includes a V-berth and a lateral twin-bunk cabin, making the boat suitable for a family or for hosting guests in privacy. While the hull remained consistent, Cheoy Lee offered several semi-custom interior variations; some owners opted for a "galley down" configuration to maximize salon seating, while others prioritized a larger dedicated navigation desk. The sibling "Offshore 53" (non-motorsailer) utilized the same hull but featured a lower profile and a more traditional cockpit-centric layout, lacking the internal steering station of the MS variant.
Popular Mentions & Media
The Offshore 53 MS holds a respected place in the archives of naval architecture, frequently cited in Robert Perry's retrospective writings as an example of the evolution of the "performance motorsailer." In his book, Yacht Design According to Perry, the designer discusses the challenges of balancing the aesthetic of a large deckhouse with a hull that still performs under sail. The model also gained visibility through the voyages of long-range cruisers who documented the boat's ability to handle the "thorny path" to the Caribbean and trans-Pacific crossings.
Known Issues & Buyer’s Checklist
Prospective buyers of an Offshore 53 MS must account for the specific maintenance requirements of a 40-year-old vessel built during Cheoy Lee's "teak-heavy" era.
- Teak Deck Integration: Like many yachts of this period, the teak decks were often fastened with thousands of screws through the fiberglass laminate into a balsa or plywood core. Over decades, these screw holes can allow moisture to penetrate the core, leading to delamination and rot. A thorough percussion test or moisture meter reading of the decks is essential.
- Fuel Tank Corrosion: The original fuel tanks were often constructed of black iron or mild steel and were "built-in" before the deck was joined to the hull. These are prone to bottom-up corrosion if moisture sits in the bilge. Replacing these tanks is a significant "engine-out" or "floor-up" project.
- Stainless Steel Bleed: Cheoy Lee utilized "in-house" stainless steel for many fittings and chainplates during the 1970s and 80s. This alloy is sometimes prone to crevice corrosion. Marine surveyors typically recommend a dye-penetrant test or proactive replacement of the chainplates for blue-water use.
- Electrical Systems: Given the complexity of the dual-helm stations and the likely addition of generators and air conditioning over the years, the wiring on many 53 MS units can become a "rat's nest" of legacy and modern systems. A full DC/AC audit is recommended.
Community & Resources
Owners of these vessels are supported by the Cheoy Lee Association, one of the most comprehensive owner-run databases in the marine world. This association provides access to original brochures, technical drawings, and a community of owners who share solutions for the specific challenges of maintaining vintage Cheoy Lee yachts, including sourcing replacement parts for proprietary hardware.
The Verdict
The Cheoy Lee Offshore 53 MS is a "gentleman’s adventurer," offering a rare blend of traditional aesthetics and pragmatic functionality. It is not a boat for those who enjoy the finesse of light-air racing, but for those who view the ocean as a space to be lived in, it is a formidable choice.
Pros
- Unmatched Protection: The dual-helm pilothouse extends the cruising season and reduces crew fatigue.
- Robust Construction: A heavy hull and ketch rig provide a sense of security in heavy weather.
- Liveability: The aft "Great Cabin" and expansive salon offer more volume than most 60-foot sailing yachts.
- Engine Range: Exceptional fuel capacity for a sailboat, allowing for reliable schedules.
Cons
- Maintenance Intensity: High teak content and vintage hardware require significant "brightwork" and technical upkeep.
- Light Air Performance: The boat is heavy and carries significant windage, requiring the engine in anything under 10-12 knots of breeze.
- Refit Costs: Systems like fuel tanks and deck cores can be prohibitively expensive to repair if neglected.
