Cobra 700 Information, Review, Specs

Sailing Performance & Handling

On the water, the Cobra 700 is characterized by its predictable and forgiving nature, a hallmark of Feltham’s naval architecture. Most hulls were produced with twin keels (bilge keels) to accommodate the drying harbors and tidal estuaries common in the United Kingdom, though a fin keel version was also manufactured for those seeking better windward performance. With a displacement of approximately 1,588 kg and a ballast ratio often hovering around 45%, the boat is notably stiff for its size. This high ballast-to-displacement ratio ensures that the vessel remains upright and composed when the breeze freshens, a quality frequently praised in owner testimonials documented by the Cobra and Seawolf Owners Association.

Handling is best described as "steady." The boat tracks well due to its significant underwater profile, though like most twin-keelers of its generation, it will experience some leeway when pushed hard into the wind. The fractional rig is manageable for solo sailors or couples, and the cockpit is deep enough to provide a high sense of security in choppy seas. While it lacks the "twitchy" acceleration of a modern sportboat, its momentum is an asset in a head sea, where lighter boats might be knocked off course.

Interior Comfort & Variations

For a vessel measuring just under 23 feet, the Cobra 700 offers a surprisingly functional interior, though it is understandably more intimate than its larger sibling, the Cobra 750. The layout typically features four berths: a V-berth in the forward cabin and two settee berths in the main saloon. The 700’s cabin is characterized by its "workmanlike" finish, utilizing molded GRP headliners and basic timber trim that prioritized durability over luxury.

The variations within the 700 series are primarily found in the transition to the Cobra 750. The 700 was effectively the progenitor; however, as the market demanded more internal volume, the 750 was introduced with increased beam and headroom. Owners moving between the two models often note that while the 700 feels more "snug" and easier to handle in a marina, the 750 offers the standing headroom that the 700 lacks for taller sailors. In the 700, the galley is modest—usually a two-burner stove and a small sink—but it is sufficient for weekend coastal hops.

Popular Mentions & Media

While the Cobra 700 has not featured prominently in major cinematic productions, it maintains a strong "cult" status within British yachting media. It is a frequent subject of "Budget Cruiser" features in publications like Practical Boat Owner and Yachting Monthly, where it is often cited as one of the best value-for-money entry-level yachts for sailors graduating from dinghies to cruisers. Its cultural footprint is most visible in the vibrant secondhand market in the UK and Northern Europe, where it is regarded as a "honest" boat that does not pretend to be more than a reliable coastal trekker.

Known Issues & Buyer’s Checklist

Potential buyers of a Cobra 700 should focus their inspection on the specific vulnerabilities of late-1970s GRP construction.

• Keel Bolts and Reinforcement: On twin-keel models, the stress points where the keels join the hull should be inspected for "smile" cracks or signs of movement, which can indicate thinning of the laminate or historical groundings.
• Deck Osmosis and Moisture: Like many boats from this era, the hull should be checked for osmotic blistering. While rarely structural, it can be a significant negotiation point.
• Window Leaks: The original aluminum-framed windows are known to develop leaks over decades, often leading to hidden rot in the interior wood bulkheads.
• Engine Maintenance: Many 700s were originally fitted with small Yanmar or Petter diesel engines. Given their age, a thorough check of the cooling system and engine mounts is essential, as many units are reaching the end of their service life.
• Rudder Play: The pintles and gudgeons on the transom-hung or spade rudders (depending on the specific build year) should be checked for excessive play, which can lead to vibration under power.

Community & Resources

The primary hub for technical support and historical data is the Cobra and Seawolf Owners Association. This organization maintains a repository of original drawings, modification guides, and a community forum where owners share specific advice on everything from re-wiring to keel reinforcement. The association is instrumental in keeping the "Cobra" legacy alive, hosting rallies and maintaining a register of the hundreds of 700s and 850s still in active use.

The Verdict

The Cobra 700 is an exemplary "first cruiser" for those who value sea-kindliness and structural integrity over modern aesthetics and interior volume. It is a stout little ship that punches above its weight in heavy weather.

Pros:

• Exceptionally stable and stiff for a 23-foot boat.
• Twin-keel versions allow for low-cost drying moorings.
• Robust construction that ages well if basic maintenance is performed.
• Highly active and supportive owners' association.

Cons:

• Limited headroom compared to the slightly larger Cobra 750.
• Twin-keel configuration results in mediocre windward performance.
• Aesthetic design is dated, reflecting its 1970s origins.
