Westerly Discus 33 Information, Review, Specs

Sailing Performance & Handling

The Discus 33 is defined by its heavy-displacement characteristics, featuring a Displacement/Length Ratio (DLR) of approximately 277. This high ratio, combined with a ballast-to-displacement ratio of 40%, results in a vessel that is exceptionally stiff and predictable. In heavy weather, the Discus "powers through the waves" rather than bouncing over them, a trait noted by the Westerly Owners Association as providing significant confidence to less experienced crews.

However, its Sail Area/Displacement (SA/Disp) ratio of roughly 14.3 confirms that the Discus is not a light-air performer. It requires a stiff breeze—typically 12 knots or more—to truly come alive. On the helm, the semi-balanced rudder on a partial skeg provides a light and responsive feel, balancing the boat's natural tendency to track straight. Most models were sloop-rigged, though a ketch variant was offered for the center-cockpit version to appeal to traditional long-distance cruisers. While it lacks the "pointing" ability of modern performance cruisers, its ability to heave-to with ease and maintain a sedate motion in a chop makes it a premier choice for blue-water coastal hops.

Interior Comfort & Variations

One of the primary selling points of the Discus 33 was its versatile layout, which came in two distinct configurations: the "Bridge Deck" (aft cockpit) and the "Center Cockpit" (aft cabin) versions. The Bridge Deck version featured a high, broad bridge between the cockpit and the companionway—a seaworthy feature that provided a sheltered lounging area under a sprayhood, though it made ingress to the saloon slightly more difficult. The Center Cockpit version was favored for extended cruising, offering a private aft cabin with an internal walkthrough, a significant upgrade in privacy for the era.

The interior joinery transitioned during production from sapele mahogany to high-quality teak, providing an atmosphere that many owners compare to the craftsmanship of Hallberg-Rassy yachts of the same vintage. With a headroom of approximately 6'3", the saloon feels remarkably airy. The three-cabin layout typically accommodates seven berths: a V-berth forward, a convertible double and single in the saloon, and a dedicated double in the aft cabin. The galley is a robust, U-shaped affair to starboard, designed for use at sea with deep stainless sinks and an icebox, as documented in original manufacturer specifications.

Popular Mentions & Media

The Westerly Discus 33 gained significant acclaim through the exploits of the Reverend Bob Shepton, a legendary Arctic explorer and mountaineer. His Discus, Dodo’s Delight, became famous in the high-latitude sailing community for its voyages to Greenland and the Canadian Arctic. Shepton’s reliance on a production Discus for such extreme conditions cemented the model's status as a formidable "pocket" blue-water cruiser. The boat is also a frequent subject of comparison in "Modern Classic" reviews by Practical Boat Owner and Yachting Monthly, where it is often pitted against its successor, the Seahawk 34, in debates over the merits of Laurent Giles' hull shapes versus later Ed Dubois designs.

Known Issues & Buyer’s Checklist

Prospective buyers should focus on three primary technical areas common to Westerlys of this vintage.

• The "Westerly Droop": The most notorious issue is the failure of the foam-backed vinyl headlining. Over time, the foam perishes into a fine orange dust, causing the vinyl to sag. Replacing this is a labor-intensive "rite of passage" for many owners, often requiring the removal of old adhesive with poly-discs on an angle grinder.
• Osmosis: Westerly hulls from the early 1980s were built before the widespread adoption of isophthalic resins. While the hulls are thick and structurally sound, osmotic blistering is common. Many listed vessels have undergone localized "peel and epoxy" treatments.
• Window Seals: The original aluminum-framed windows are prone to leaking as the bedding compound dries out. Re-sealing or replacing these with modern units from suppliers like Eagle Boat Windows is a common upgrade.
• Engine Service: Many Discuses were originally fitted with the Mercedes OM636 or the Volvo MD17. While robust, parts for the Mercedes are becoming increasingly specialized. Potential buyers should verify if the engine has been re-powered with a modern Beta or Yanmar unit.

Community & Resources

The Westerly Owners Association is one of the largest and most active owner groups in the world. It provides a comprehensive technical "Wiki" and a magazine that serves as a vital repository for DIY maintenance guides and historical brochures. Additionally, the Laurent Giles Archive maintains the original design plans and technical drawings for the Discus, which are available for owners seeking to perform structural repairs or restorations.

The Verdict

The Westerly Discus 33 is a "sailor's sanctuary," offering a level of build quality and heavy-weather security that is increasingly rare in the modern production market. It is an ideal vessel for families or couples who value comfort and safety over regatta-winning speeds.

Pros:

• Exceptional Stability: High ballast ratio and heavy displacement ensure a comfortable, upright ride.
• Superior Joinery: The interior teak and sapele finishes are significantly more durable than modern veneers.
• Seaworthy Layout: The bridge-deck and center-cockpit options offer excellent safety and privacy for long passages.
• Massive Storage: Designed for extended stays, with ample lockers and large water/fuel capacities.

Cons:

• Light Air Sluggishness: Requires significant wind to move effectively; frequently requires motoring in light breezes.
• Maintenance "Gotchas": The sagging headlining and potential for osmosis require a diligent pre-purchase survey.
• Aged Systems: Original engines and wiring often require modernization for reliable cruising.
