Cobra 1050 Information, Review, Specs

Sailing Performance & Handling

The Cobra 1050 is a heavy-displacement cruiser that prioritizes sea-kindliness and stability over raw speed. With a ballast ratio typically hovering around 35–40%, the boat is notably stiff, capable of carrying full sail well into a Force 4 before requiring a reef. According to technical archives from the Cobra and Seawolf Owners Association, the vessel was offered with two main underwater profiles: a deep fin keel for improved windward performance and a twin (bilge) keel version designed for the drying harbors of the UK’s South and East coasts.

On the water, the 1050 feels deliberate and secure. The David Feltham hull shape features a relatively fine entry that transitions into a wide beam carried well aft, which helps the boat track well when reaching. However, the high freeboard and substantial coachroof profile create significant windage; in light airs, the 1050 can feel sluggish, and it requires a dedicated cruising chute or a large genoa to maintain momentum. When the wind picks up, the boat finds its stride, offering a predictable, "dry" ride as the flared bow deflects spray effectively. It is not a yacht for the club racing circuit, but for a navigator crossing the English Channel or the North Sea, its predictable motion in a seaway is a significant asset.

Interior Comfort & Variations

The interior of the Cobra 1050 was considered revolutionary for its time, offering a level of "tardis-like" space that challenged the contemporary offerings from larger builders like Westerly or Moody. The standard layout features a spacious main saloon with a U-shaped settee to starboard and a linear settee to port, providing ample seating for six adults. A defining characteristic of the 1050 is the generous headroom, which remains consistent through much of the cabin, catering to taller sailors who often struggle in 34-footers of this vintage.

Accommodation is typically split into a forward V-berth cabin and a dedicated aft cabin or large quarter berth, depending on the specific year of manufacture. The galley is generally positioned to starboard at the base of the companionway, featuring a deep sink and ample stowage for extended victualing. Because Cobra Yachts sold a significant number of these vessels as "kit boats" for home completion, the quality and configuration of the interior can vary wildly between hulls. Some owners opted for high-end teak joinery and professional upholstery, while others utilized more utilitarian plywood finishes. Potential buyers should also note the transition to the Seawolf 35; while the hull remained the same, the Seawolf versions often featured a revised deck mold and a more modernized interior layout, frequently including a more private aft cabin arrangement.

Known Issues & Buyer’s Checklist

• Hull Osmosis: Like many GRP yachts built in the late 1970s, Cobra 1050s are susceptible to osmotic blistering. While rarely structural, hulls that have not undergone a professional epoxy treatment may require significant bottom work.
• Kit-Built Variability: Because many 1050s were completed by their first owners rather than the factory, the quality of the electrical wiring, plumbing, and gas installations must be scrutinized. Non-standard fuse panels or amateurish joinery are common "gotchas" that can complicate insurance surveys.
• Engine Service Life: Many original units were fitted with Bukh or Yanmar diesel engines. Given the age of these vessels, many have reached the end of their reliable service life. A documented engine replacement or a rigorous professional compression test is essential.
• Deck Core Integrity: The deck is a sandwich construction. Buyers should check for "soft spots" or delamination, particularly around high-load areas like the mast step, stanchion bases, and the windlass, where water ingress can rot the core over decades.
• Chainplate Inspection: The shroud attachments (chainplates) are known to be robust, but the sealant around the deck penetrations can fail, leading to slow leaks that may damage the bulkheads below.

Community & Resources

The primary hub for technical support and historical documentation is the Cobra and Seawolf Owners Association. This organization maintains a repository of original brochures, sail plans, and technical advice specifically for the Feltham-designed range. The association is instrumental in helping owners identify whether their specific hull was factory-finished or a home-build project, and they provide a network for sourcing spare parts for the unique cast-iron keels used on the 1050.

The Verdict

The Cobra 1050 is a quintessential "honest" cruiser—a boat that trades sleek aesthetics for immense internal volume and a secure, upright sailing experience. It remains one of the most cost-effective ways to acquire a 34-foot offshore-capable yacht with enough room for a full family.

Pros:

• Exceptional interior volume and headroom for its length.
• Sturdy, heavy-weather performance with a stiff sailing attitude.
• Versatile keel options, including a capable bilge keel variant for shallow drafts.
• Strong community support through a dedicated owners' association.

Cons:

• High windage can make close-quarters maneuvering under power challenging.
• Significant variability in interior finish due to the prevalence of kit-built boats.
• Dated deck hardware and original engines often require immediate capital investment.
