Cobra 750 Information, Review, Specs

Sailing Performance & Handling

The sailing characteristics of the Cobra 750 are defined by its substantial beam of 9 feet 6 inches and a high ballast-to-displacement ratio of nearly 42%. This geometry creates a notably "stiff" boat that resists heeling, making it a forgiving platform for novice sailors or families with young children. Most 750s were configured as masthead sloops with twin bilge keels, a setup favored for its ability to dry out in tidal harbors. While the bilge keel version naturally suffers from more leeway when sailing close-hauled compared to the rarer fin-keel variant, the boat’s weight—displacing over 5,000 lbs—provides a sense of security and "big boat" momentum in a chop.

Under sail, the Cobra 750 is not a light-airs performer. Its moderate sail area-to-displacement ratio means it requires a decent breeze to come alive. However, once the wind reaches Force 3 or 4, the hull settles into a predictable groove. Owners frequently note that the boat carries its canvas well into higher wind ranges before reefing becomes necessary. According to technical data maintained by the Cobra and Seawolf Owners Association, the hull’s underwater profile was optimized for stability over raw speed, ensuring that the boat remains manageable even when the North Sea or English Channel turns unruly.

Interior Comfort & Variations

For a 25-foot yacht designed in the late 1970s, the interior of the Cobra 750 is often described as "Tardis-like." The generous beam allows for a layout that usually includes five berths: a double V-berth in the forecabin, a saloon dinette that converts to a double, and a single quarter berth to port. The use of a GRP inner molding in factory-finished boats gives the cabin a clean, bright feel, though many vessels have been upgraded over the decades with bespoke woodwork.

Headroom is a standout feature, reaching approximately 5 feet 10 inches in the main saloon—a rarity for a boat of this length. The galley is typically located to starboard, featuring a gimballed stove and a modest sink, while a separate heads compartment (toilet) is situated between the saloon and the forecabin. Because the Cobra 750 was a sibling to the Cobra 850, it inherited much of the larger boat's ergonomic logic, including a dedicated chart table that is functional enough for coastal navigation.

Known Issues & Buyer’s Checklist

Prospective buyers of a Cobra 750 should focus on the following technical areas, which are common across the David Feltham-designed Cobra range:

• Deck Core Integrity: Like many GRP boats of this era, the decks are a sandwich construction. Over time, deck fittings (cleats, stanchion bases) can leak, leading to moisture ingress and delamination of the core. Soft spots underfoot are a primary red flag.
• Keel Bolt Inspection: On bilge keel models, the stresses of drying out on hard ground can fatigue the hull-to-keel joints. Look for "smile" cracks at the leading edge of the keels or evidence of water weeping from the bolts.
• Original Engines: Many 750s were originally fitted with Yanmar YSE8 or Bukh 10 diesel engines. While these are legendary for their durability, they are now roughly 45 years old. Check for heavy smoking, ease of cold starting, and the condition of the sail drive seal if a sail drive was fitted.
• Window Seals: The large acrylic side windows are a hallmark of the model’s bright interior, but they are prone to leaking. If the interior wood trim shows water staining, the windows likely require re-bedding or replacement.
• Home-Completion Variations: Since many were sold as kits, the quality of electrical wiring and plumbing can vary wildly. A professional survey is essential to ensure that the "amateur" interior installations meet modern safety standards.

Community & Resources

The primary hub for technical support is the Cobra and Seawolf Owners Association, which serves owners of the Cobra 700, 750, 850, and 1050, as well as the Seawolf 26 and 30. This group provides a repository of original brochures, rigging diagrams, and a collective knowledge base for maintaining these classic British hulls.

The Verdict

The Cobra 750 is an over-engineered, high-volume cruiser that offers exceptional value for those prioritizing cabin space and stability over racing performance. It is a stout "small-big boat" that remains one of the most practical entry-level cruisers on the secondhand market.

Pros:

• Exceptional interior volume and headroom for its length.
• High stability and "stiff" sailing characteristics.
• Bilge keel options are ideal for tidal moorings and drying out.
• Strong, active owners' association for technical support.

Cons:

• Sluggish performance in light winds.
• Aged original engines may require replacement.
• Higher leeway in bilge-keel versions compared to contemporary fin-keelers.
• Variability in build quality due to kit-completed examples.
