Sloop W/Bowsprit Endeavour 37 Information, Review, Specs

Sailing Performance & Handling

The Endeavour 37 is a traditional, heavy-displacement cruiser that prioritizes "sea-kindliness" and directional stability over agility. With a displacement of approximately 21,000 pounds and a shoal draft of just 4 feet 6 inches, the boat is designed to negotiate thin water without sacrificing the tracking benefits of a long keel with a cutaway forefoot. This configuration allows the yacht to track exceptionally well on a reach, though its performance to weather is somewhat hampered by the shallow draft and the aerodynamic drag of its wide beam.

The sloop version equipped with a bowsprit significantly improves the yacht’s balance compared to the standard sloop rig. By moving the center of effort forward, the bowsprit helps mitigate the weather helm that often plagues wide-stern cruisers in heavy air. In light air, the 37 requires a large genoa to overcome its significant inertia. The Endeavour Owners Group technical archives suggest that while the boat is not a "racer," it remains remarkably stiff and predictable in a blow, often staying upright and controlled while lighter, more modern designs are forced to reef early.

Interior Comfort & Variations

The interior of the Endeavour 37 was a major selling point and a primary reason for its success in the charter and liveaboard markets. The boat was offered in two distinct interior configurations: "Plan A" and "Plan B." Plan A features a traditional layout with a large V-berth forward, a U-shaped galley to port, and a settee to starboard. Plan B, which is often preferred by couples, incorporates a larger aft quarter-berth and a slightly rearranged salon to maximize social space.

Both versions benefit from the boat’s nearly 12-foot beam, which provides an expansive feel rarely found in 1970s-era 37-footers. Headroom is a standout feature, reaching approximately 6 feet 6 inches in the main salon. The use of teak bulkheads and solid teak trim gives the interior a warm, traditional aesthetic. Because the Endeavour 37 was built on the same hull as the Ketch variant, the interior volume remains consistent across rig types, though the sloop’s lack of a mizzen mast simplifies the aft cabin or cockpit ergonomics.

Known Issues & Buyer’s Checklist

Prospective buyers should approach the Endeavour 37 with a focus on its 1970s-era construction techniques. While the hulls are solid fiberglass, the decks were cored with plywood or balsa squares. Over decades, rebedding of stanchions and chainplates is often neglected, leading to core saturation.

• Fuel Tank Corrosion: The original Endeavour 37s were often fitted with black iron fuel tanks located deep in the bilge. These are notorious for rusting from the outside in if water is allowed to sit in the bilge, a common issue in older boats. Replacement often requires significant joinery work.
• Chainplate Inspection: The chainplates on the 37 are mounted externally to the hull. While this makes them easy to inspect, the bolts penetrate the hull-to-deck joint area. Leaks here can lead to rot in the structural bulkheads that support the rig.
• Rudder Delamination: The rudder is a fiberglass shell filled with foam around a stainless steel post. It is common for water to ingress the foam, leading to internal corrosion of the "ears" welded to the post or delamination of the skins.
• Propeller Shaft Alignment: Due to the long keel and engine placement, some owners report difficulty with shaft alignment if the engine mounts have settled or if the hull has flexed over decades of being blocked incorrectly on land.

Community & Resources

The primary hub for technical support is the Endeavour Owners Group, which maintains an exhaustive database of original manuals, brochures, and "owner-mod" guides. This association is one of the most active for vintage American fiberglass boats, providing specific parts sourcing for the Perkins or Yanmar engines commonly found in these hulls.

The Verdict

The Endeavour 37 Sloop with Bowsprit is a purposive cruiser that trades high-performance metrics for comfort and shallow-water accessibility. It remains a top choice for sailors on a budget looking to cruise the Intercoastal Waterway or the Bahamas.

Pros:

• Exceptional interior volume and headroom for its length.
• Shoal draft is ideal for Florida and Bahamian cruising.
• Stable, predictable motion in heavy seas.
• Strong owner community and parts availability.

Cons:

• Relatively sluggish in light winds and poor upwind pointing.
• Maintenance-heavy teak-and-plywood construction.
• Black iron fuel tanks are a common failure point.
