Endeavour 37 Yawl Information, Review, Specs

Sailing Performance & Handling

Under sail, the Endeavour 37 Yawl is a steady, predictable performer that favors comfort over speed. With a displacement of approximately 21,000 pounds and a ballast-to-displacement ratio hovering around 38%, the boat is notably stiff. The hull features a long, modified fin keel with an encapsulated lead ballast and a large skeg-hung rudder, a combination that provides excellent tracking but results in a relatively wide turning radius in tight marinas.

The yawl rig offers distinct advantages for short-handed cruising. In heavy weather, sailors can employ the "mizzen and jib" configuration, which keeps the boat balanced and manageable without the need for a heavily reefed mainsail. According to technical archives maintained by the Endeavour Owners Group, the Sail Area/Displacement (SA/Disp) ratio is roughly 13.8, confirming its identity as a "heavy cruiser." It requires a stiff breeze—typically 12 knots or more—to truly find its groove. In light air, the boat can feel sluggish, though the addition of a mizzen staysail on the yawl version can provide a much-needed boost when reaching.

Interior Comfort & Variations

The Endeavour 37 was celebrated for an interior volume that rivaled many 40-footers of its era. The boat was primarily offered in two distinct interior configurations: Plan A and Plan B. Plan A is the more traditional cruising layout, featuring a V-berth forward, a port-side head with a separate shower stall, and a salon with a drop-leaf table. Plan B, sometimes referred to as the "European" or "Charter" layout, moved the galley forward and offered a different arrangement of the settee and navigation station to maximize floor space.

The craftsmanship is characterized by extensive use of teak—including teak and holly soles and teak-veneered bulkheads—which provides a warm, classic nautical ambiance. With 6’6” of headroom in the main salon, the E37 remains a top choice for taller sailors. The sibling model, the Endeavour 37 Sloop, utilizes the exact same hull and interior options but lacks the second mast, offering a slightly simpler rig for those who do not require the sail-tuning nuances of a yawl.

Known Issues & Buyer’s Checklist

Potential buyers should approach the Endeavour 37 with a focus on three primary technical areas:

1. Deck Core Integrity: Like many boats of this vintage, the E37 utilized plywood squares for deck coring. If hardware was not properly re-bedded, water can migrate into these blocks. Observers should check for soft spots, particularly around the chainplates and stanchion bases.
2. Chainplate Anchoring: The chainplates are mounted to the exterior of the hull, which prevents leaks into the interior but exposes the bolts to constant saltwater contact. These should be pulled and inspected for crevice corrosion.
3. Engine Access and Maintenance: Most E37s were powered by the Perkins 4-108 or the Westerbeke 40. While these are "bulletproof" engines, the engine room on the E37 is notoriously tight. Prospective owners should check the condition of the raw water pump and heat exchanger, as these are difficult to service in situ.
4. Fuel Tank Material: The original fuel tanks were often made of aluminum and sat in the bilge areas. Over four decades, bottom-up corrosion can occur if the tanks were frequently sitting in damp conditions.

Community & Resources

The model is supported by one of the most robust owner associations in the American marine industry. The Endeavour Owners Group serves as the primary repository for original factory manuals, wiring diagrams, and a comprehensive database of owner-led modifications. This community is an essential resource for sourcing replacement parts that are no longer in production by the original builder.

The Verdict

The Endeavour 37 Yawl is an ideal "first big boat" for a cruising couple or a family looking to explore coastal waters and the Caribbean. While it won't win many windward races, its rugged construction and immense living space make it a standout value in the used market.

Pros:

• Exceptional Headroom: 6’6” clearance is rare in a 37-foot vintage hull.
• Shoal Draft: Ideal for exploring shallow bays and the Bahamas.
• Rig Versatility: The yawl rig provides numerous sail-balance options for heavy weather.
• Massive Storage: Designed for long-term provisioning and live-aboard comfort.

Cons:

• Light Air Performance: Struggles in winds under 10 knots without specialized light-air sails.
• Engine Access: Tight quarters make routine maintenance a challenge for DIY owners.
• Wide Turning Radius: The long keel and skeg rudder make backing into slips difficult without practice.
