Grand Soleil 37 Race Information, Review, Specs

The 37 Race was part of a prestigious performance family that included the Grand Soleil 42 Race and 56 Race, all of which shared a focus on optimizing hull lines for the then-dominant IMS rating system. While the "Cruiser" variant of the same hull utilized a slightly more conservative rig and keel, the "Race" version is distinguished by its taller 9/10 fractional rig, deeper draft of approximately 2.4 meters, and a lead-bulb keel designed to lower the center of gravity for maximum stiffness.

Sailing Performance & Handling

The sailing characteristics of the Grand Soleil 37 Race are defined by its responsiveness and exceptional pointing ability. According to editorial testing by Sail Magazine, the vessel demonstrates a nimble nature around crowded starting lines, capable of turning within its own boat length. The 9/10 fractional rig, typically equipped with swept-back double spreaders and rod rigging on racing configurations, provides a powerful sail-area-to-displacement (SA/Disp) ratio that comfortably exceeds 20, putting it firmly in the high-performance category.

In light air, the boat remains sensitive and responsive at the wheel, benefiting from a balanced rudder blade (sometimes carbon on pure racing setups) and a low-friction steering system. Its Displacement/Length (D/L) ratio of approximately 183 categorizes it as a moderate-to-light racer, allowing for rapid acceleration in puffs. However, its stability index of 115.2 and a ballast ratio of roughly 33% ensure it remains stiff enough to "stand up" to its large mainsail even when the breeze freshens. Technical data from the Diamond Yachts specification profile notes that the boat’s ergonomics are optimized for a full racing crew, with the mainsheet traveler positioned behind the tiller or wheel for fine-tuned control.

Interior Comfort & Variations

Despite its racing pedigree, the interior of the Grand Soleil 37 Race is surprisingly refined, utilizing high-quality mahogany joinery finished with polyurethane. The shipyard offered two primary configurations: a two-cabin "Owner’s" version and a three-cabin layout. The two-cabin variant is highly favored for cruising, as it relocates the head to allow for a dedicated separate shower stall and a larger port-side lazarette locker for sail storage. The three-cabin version features mirror-image aft staterooms, which is more common for race teams needing maximum berthing for a delivery crew.

Living spaces are surprisingly bright due to multiple opening hatches and a low coachroof design. Headroom is generous for a 37-foot performance boat, reaching approximately 1.90 meters in the main salon. The galley is typically configured in a longitudinal or L-shape, featuring a 12V refrigerator and twin-burner stove. While the interior is often described as "purposeful" rather than "lavish," the fit and finish are significantly higher than that of high-volume production competitors.

Known Issues & Buyer’s Checklist

Prospective buyers of a Grand Soleil 37 Race should focus on specific technical areas that are common to this performance-oriented construction:

• Galvanized Steel Grid: The internal steel frame is the backbone of the boat. It must be inspected for signs of rust or delamination from the hull. Any water sitting in the bilge for extended periods can accelerate corrosion of the galvanized coating, particularly around the keel bolts.
• Keel-to-Hull Joint: Given the deep 2.4m draft and the high leverage of the lead bulb, the keel joint should be checked for "smile" cracks. These boats were often raced hard; any history of groundings should be thoroughly investigated.
• Rudder Bearings: The self-aligning ball bearings on the rudder shaft are subject to high loads. Excessive play or stiffness in the wheel may indicate that the bearings are nearing the end of their service life.
• Saildrive Seal: Most units are powered by a Volvo Penta diesel with a saildrive. The rubber diaphragm (bellows) has a manufacturer-recommended replacement interval (typically 7 years); buyers should verify the age of this seal.
• Deck Core: While the vacuum-bagged construction is generally robust, the deck is a foam-core sandwich. Inspection with a moisture meter around stanchion bases and winches is critical to ensure no water ingress has compromised the core.

Community & Resources

The Grand Soleil 37 Race enjoys a strong following in European waters, particularly within the ORC and IRC racing communities. The ORC (Offshore Racing Congress) maintains a vast database of measurement certificates for this model, which can provide technical specifics on individual sail plans and ballast configurations. Owners also frequently congregate under the umbrella of broader Mediterranean sailing associations, given the shipyard's location in Forlì, Italy.

The Verdict

The Grand Soleil 37 Race is a quintessential racer-cruiser that successfully bridges the gap between IRC trophy hunting and weekend family cruising. It remains a sought-after model for sailors who refuse to sacrifice Italian style for boatspeed.

Pros:

• Exceptional upwind pointing and light-air acceleration.
• Robust construction utilizing a load-bearing steel internal grid.
• Elegant, high-quality mahogany interior that defies its "Race" moniker.
• Competitive IRC/ORC ratings that remain relevant in the used market.

Cons:

• The deep 2.4m draft significantly limits access to shallow anchorages and certain marinas.
• The galvanized grid requires diligent maintenance to prevent corrosion.
• The racing-optimized deck layout may feel cluttered to pure cruisers.
