Design Brief & Intent
Westerly built the Ocean 37 to serve as a fast, premium offshore cruiser capable of long-distance voyaging, while remaining manageable enough for a couple to handle with ease. Ed Dubois achieved this by taking the successful 1990s Typhoon hull—noted for its good manners and excellent upwind capability—and pairing it with a taller, 9/10 fractional sloop rig and modernized foils. The construction standards were exceptional: hand-laid in a temperature-controlled environment with Lloyds-certified layups, incorporating solid GRP laminates below the waterline and a balsa-core deck backed by heavy backing pads under all load-bearing hardware.
Unlike its competitors of the era that emphasized dockside accommodation, the Ocean 37 retained a classic, moderate-displacement profile with a deep, relatively narrow aft cockpit. This design feature offers superior physical security when heeled and keeps the helm and crew protected in heavy weather. Below decks, the interior joinery was finished to a high standard, showcasing traditional teak or mahogany and a level of cabinetmaker’s craft that stands as a stark contrast to modern, modular liners.
Variations & Configurations
The Ocean 37 was offered in two primary configurations: an Owner's layout and a multi-cabin family or charter layout. The Owner's version features a two-cabin, two-head arrangement that prioritizes long-term liveaboard comfort. In this layout, the aft cabin is remarkably spacious for an aft-cockpit boat of this length, offering a large double berth, dedicated settee space, and direct access to an ensuite head. The galley is a sea-safe U-shape, allowing the cook to wedge securely in place while underway, and the navigation station is a full-sized, forward-facing desk with dedicated chart storage.
The charter or multi-cabin configuration optimizes sleeping capacity with three cabins, replacing some of the spaciousness of the aft master stateroom with twin double cabins to accommodate larger crews. Under the water, the Ocean 37 was configured with a deep iron fin keel drawing six feet and a high-aspect spade rudder, maximizing lift and pointing ability.
Sailing Performance & Handling 4
On the water, the Ocean 37 is responsive, stiff, and exceptionally light on the helm. Thanks to its Dubois-designed pedigree, the hull features a relatively narrow entry at the waterline, which translates into superb windward performance and the ability to tack through a tight eighty-degree angle. The forward sections provide ample reserve buoyancy to prevent slamming or burying the bow, while the substantial stern sections maximize waterline length and power when reaching.
Equipped with a taller mast and larger mainsail than the original Typhoon, the Ocean 37 sets roughly thirty-three percent more sail area upwind than average cruisers of its size. Despite this increased power, the yacht does not feel nervous or overpowered. The fractional rig allows the helmsman to easily flatten the mainsail using backstay tension, and cockpit-led reefing lines enable a single watchkeeper to tuck in a reef in under a minute when the wind builds.
Modernization & Triage
Because of the low production volume during the final years of Westerly Marine, the Ocean 37 is a rare find. Buyers looking to acquire one should distinguish its build from the earlier Typhoons. Early Typhoons experienced some minor bonding issues with the internal "egg-crate" grid reinforcement, which was a known structural failure point that Westerly quickly recalled and reinforced. Ocean 37 models, built much later, benefited from these refined structural layups out of the box.
When assessing an Ocean 37 today, the primary triage focus centers on the propulsion system. Most models were fitted with a Yanmar or Volvo Penta diesel engine coupled to a saildrive. Standard maintenance requires replacing the saildrive rubber hull diaphragm every seven to ten years, which is a labor-intensive haul-out job. Additionally, while the late-era Westerly yachts featured upgraded headlining materials, buyers should still carefully inspect the cabin ceilings for signs of sagging, a common issue across many classic British yachts of this vintage. Upgrading to modern lithium-iron-phosphate battery banks is a popular refit pathway, as the factory-installed alternator and battery storage capacity were designed for simpler, pre-digital cruising needs.
The Verdict 2
The Westerly Ocean 37 is a masterpiece of late-era British yacht design, offering a rare blend of Dubois-designed sailing performance and robust, ocean-going construction. It stands as an ideal choice for the blue-water traditionalist who wants a yacht that is fast, safe, and beautifully built, without sacrificing the safety of a deep, secure cockpit.
Pros 4
- Outstanding upwind pointing ability and incredibly light, responsive helm manners.
- High-quality, hand-laid hull with robust construction and a Lloyds certification pedigree.
- Secure, deep aft cockpit designed for genuine physical safety in heavy weather.
- Extremely comfortable and practical layout in the Owner's two-cabin configuration.
- Strong residual value and high-end appeal compared to generic, mass-production cruisers.
Cons
- High rarity on the brokerage market makes finding one a significant challenge.
- Lower overall interior volume and headroom compared to modern, wide-beamed cruising designs.
- Standard saildrive configuration requires periodic, labor-intensive diaphragm maintenance.
- Darker interior woodwork can make the saloon feel less bright than contemporary, window-heavy designs.
