C&C 51 Custom Information, Review, Specs

Sailing Performance & Handling

The sailing characteristics of the C&C 51 Custom are defined by its Bill Tripp pedigree, which emphasizes a high power-to-weight ratio and exceptional balance. Unlike the heavier, more conservative cruisers of the previous decade, the 51 Custom utilized a vacuum-bagged epoxy, E-glass, and Kevlar composite construction. This advanced layup resulted in a rigid, lightweight hull that remains responsive even in light air. According to historical design archives from Tripp Design Naval Architecture, the hull features a high-aspect-ratio spade rudder and a deep fin keel, which provide the tracking and lift necessary for competitive upwind performance.

Under sail, the boat is known for its "big boat" stability paired with the agility of a smaller racer. The fractional rig and large foretriangle allow for a versatile sail plan, though the boat truly shines in reaching conditions where its long waterline and flat aft sections encourage surfing. Handling is described by owners as precise, though the high loads of a 51-foot performance yacht require a skilled crew or powerful winches. The sail area-to-displacement ratio is aggressive, placing the 51 Custom firmly in the "Performance Cruiser" category, capable of maintaining high average speeds during long-distance passages.

Interior Comfort & Variations

The interior of the C&C 51 Custom reflects the luxury expectations of a 1990s flagship. While the exterior is built for speed, the living spaces were designed for extended periods at sea or entertaining in port. The standard layout typically features a three-cabin, two-head configuration, with a spacious owner’s suite forward and two symmetrical guest cabins aft. The use of high-grade cherry or teak joinery—a hallmark of the Niagara-on-the-Lake craftsmen—is prevalent throughout the salon and galley.

During its short production window, C&C explored variations to suit different owner requirements. Some hulls were outfitted with a more "racy" minimalist interior to save weight for IMS competition, while others received the full "Custom" treatment with specialized navigation stations and gourmet galleys. The 51 Custom’s sibling, the Tripp-designed C&C 45 IMS, shared many of these interior aesthetic cues but on a slightly smaller scale. The headroom is generous, often exceeding 6'4" in the main salon, and the integration of numerous deck hatches ensures that the interior remains bright and well-ventilated, addressing a common complaint regarding older C&C designs.

Known Issues & Buyer’s Checklist

Prospective buyers of a C&C 51 Custom must account for the complexity of its 1990s-era systems and its specialized construction. High-signal technical areas for inspection include:

• Epoxy/Core Integrity: While epoxy is superior to polyester resin in terms of osmosis resistance, the balsa or foam core must be checked for moisture, particularly around deck hardware and thru-hull fittings. Use a moisture meter and perform a percussion (hammer) test on the deck and topsides.
• Keel Attachment: Given the boat’s performance orientation, the keel-to-hull joint (the "smile") should be inspected for signs of stress or movement, especially if the vessel has been campaigned in offshore races.
• Rigging Loads: The 51 Custom carries a powerful rig. Chains plates and the mast step should be examined for hairline fractures or deformation. Many of these boats were fitted with rod rigging, which has a finite lifespan and may require expensive replacement if it is more than 10-12 years old.
• Plumbing and Wiring: Because these boats were built during a transitional period for the company, some owners have noted that the wiring and plumbing runs can be complex to access behind the high-quality cabinetry.

Community & Resources

Owners of the C&C 51 Custom benefit from the broader C&C community, which is one of the most active in North America. The C&C Photo Album & Resource Center serves as an essential repository for technical drawings, brochures, and historical data for all models, including the rare 51. Additionally, because the boat was designed by Bill Tripp, the Tripp Design firm remains a point of contact for technical inquiries regarding the hull’s structural specifications and original sail plans.

The Verdict

The C&C 51 Custom is a sophisticated "thoroughbred" that offers a unique blend of 1990s craftsmanship and modern performance geometry. It is best suited for the experienced sailor who desires a fast, offshore-capable yacht with an elegant interior, and who is willing to maintain the complex systems associated with a flagship vessel.

Pros:

• Exceptional performance pedigree from Tripp Design.
• Advanced epoxy/Kevlar construction provides superior strength and lightness.
• High-quality interior joinery typical of C&C’s best years.
• Significant "ramp appeal" due to its sleek, timeless lines.

Cons:

• Deep draft (often over 8 feet) limits access to shallow harbors and coastal cruising grounds.
• Extremely limited production makes finding specific replacement parts or "sister ship" advice difficult.
• High maintenance requirements for the rig and high-load deck hardware.
