Cooper 508 Information, Review, Specs

Sailing Performance & Handling

The Cooper 508 is fundamentally a heavy-displacement cruiser, weighing in at approximately 38,350 pounds. This mass, combined with a substantial 16,500 pounds of ballast, grants the boat a ballast-to-displacement ratio of roughly 43%, according to technical records on Wikipedia. In practical terms, this makes the 508 an exceptionally "stiff" boat that resists heeling and maintains a steady platform in heavy weather. While its Sail Area to Displacement ratio (SA/D) of 17.43 suggests it is more of a powerful cruiser than a light-air racer, the hull’s Displacement to Length (D/L) ratio of 201 indicates it is surprisingly nimble for its size, sitting on the lighter side of the "moderate" category for offshore monohulls.

Under sail, the masthead sloop rig is designed for simplicity and durability. The fin keel and skeg-mounted rudder provide a balance of maneuverability in tight marinas and tracking stability in following seas. Owners often report that the boat feels "planted" and secure, though its 8-foot draft is a significant consideration for those planning to cruise the shallower waters of the Bahamas or the U.S. East Coast. It is a vessel built to be driven by a robust 85hp Lehman diesel when the wind fails, a configuration that reflects the "motorsailer" influence often seen in Stan Huntingford's larger designs, such as the Maple Leaf series.

Interior Comfort & Variations

The hallmark of the Cooper 508 is its massive interior volume, facilitated by a large raised deckhouse and a flush deck forward. This "Super Cooper" layout, as it was famously dubbed by Dan Spurr in a 1983 review for Cruising World, allows for a bright, airy main salon with expansive windows that are uncommon for yachts of this era. Beneath the raised cabin sole lies the engine room, providing centralized access to the 85hp Lehman and the generator—a design choice that prioritizes mechanical maintenance and keeps the weight of heavy machinery low and centered in the hull.

The standard layout features sleeping accommodations for seven. This typically includes a spacious aft master stateroom made possible by the center-cockpit configuration, a large galley to port, and an offset double V-berth in the bow. Because the production run was limited to five hulls, customization was common; some variations may feature different cabinetry finishes or head configurations. The use of heavy teak joinery and solid fiberglass construction was standard, reflecting the builder's reputation for high-quality craftsmanship detailed in the 2023 Pacific Yachting obituary of Forbes Cooper. While the 508 did not have direct "sibling" variations like a 4-cabin charter version, it shares significant DNA with the Maple Leaf 48 and the later Cooper 516, which utilized similar Huntingford hull lines and interior philosophies.

Popular Mentions & Media

In the early 1980s, the Cooper 508 was a centerpiece of the Canadian marine industry's attempt to compete with high-end American cruisers. The most significant media coverage came from Cruising World in May 1981, which praised the boat's ability to "sleep a tribe of voyagers" and highlighted its unique aesthetic, tailored for the harsh climatic conditions of the North Pacific. More recently, the boat's legacy has been kept alive through the historical archives of Pacific Yachting, which noted the 508 as a key model in Forbes Cooper's move from small production sailboats to large-scale custom yachts.

Known Issues & Buyer’s Checklist

Given the age and rare production of the Cooper 508, a specialized survey is mandatory. Potential buyers should focus on the following high-signal areas:

• Deck Coring: Like many yachts from the 1980s, the 508 utilized a cored deck. Inspect the areas around the raised deckhouse windows and the flush deck forward for signs of moisture ingress or delamination, which can be an expensive repair on a boat of this scale.
• Chainplates and Standing Rigging: Because the 508 was built for offshore work, the original chainplates may be nearing the end of their fatigue life if they haven't been replaced. Accessing them behind the heavy interior teak cabinetry can be labor-intensive.
• Engine Access and Seals: While the engine room is spacious, the seals around the raised deckhouse hatches should be checked. Any leaks here can drip directly onto the Lehman diesel or electrical components.
• Rudder Skeg Integrity: The skeg-mounted rudder is a robust design, but the connection point between the skeg and the hull is a high-stress area that should be inspected for stress cracks or "smile" lines at the leading edge.

The Verdict

The Cooper 508 is a "black swan" of the cruising world—a massive, well-built Canadian yacht that vanished from production just as it was reaching its stride. It is an ideal vessel for a family or couple looking for a true liveaboard that can handle blue-water passages with ease.

Pros:

• Exceptional interior volume and natural light via the raised deckhouse.
• High ballast ratio (43%) ensures a stiff, safe, and comfortable ride in heavy seas.
• Excellent engine access and mechanical layout for long-range cruising.
• Robust Stan Huntingford design with a proven pedigree for seaworthiness.

Cons:

• Deep 8-foot draft limits coastal cruising and gunkholing options.
• Extremely rare (only 5 built), making parts-specific knowledge and resale comparisons difficult.
• Standard 1980s maintenance concerns, specifically regarding deck coring and aging electrical systems.
