Corsair 24 Mk II Information, Review, Specs

Sailing Performance & Handling

The performance of the Corsair 24 Mk II is defined by its massive righting moment and a high sail area-to-displacement ratio, features common to the Corsair Marine design philosophy. Unlike monohulls of similar length that heel significantly under load, the 24 Mk II remains relatively flat, converting wind pressure directly into forward kinetic energy. In light air, the boat is notoriously sensitive, often moving at wind speed, while in a stiff breeze, it is capable of sustained speeds in the mid-to-high teens.

Central to its handling is the rotating wing mast, which optimizes the leading edge of the mainsail for superior aerodynamics. The boat utilizes a daggerboard rather than a fixed keel, which significantly reduces drag and allows for impressive upwind pointing angles—often exceeding those of contemporary racer-cruiser monohulls. However, sailors transitioning from monohulls must adjust to the "multihull hum," where the lack of heeling can mask the true force of the wind, requiring proactive reefing. Handling is generally considered light and responsive, though the high speeds can make the helm feel sensitive when reaching in a seaway.

Interior Comfort & Variations

For a 24-foot vessel, the Corsair 24 Mk II offers a surprisingly functional interior, though it remains firmly in the "compact cruiser" category. The cabin provides a V-berth forward and two narrow settee berths in the main salon, suitable for a small family or two couples for a weekend. A signature feature of the Mk II is the "pop-top" companionway cover, which provides essential standing headroom and increased ventilation when the boat is at anchor or at the dock.

The interior aesthetic is utilitarian, utilizing molded fiberglass liners and lightweight materials to keep the overall displacement low. While the original F-24 was more sparse, the Mk II benefited from Corsair’s refined production processes, offering slightly better finish quality and more ergonomic storage bins. Sibling variations of this hull include the "Sprint 750," which stripped back the interior to create a more dedicated day-racing platform with a larger cockpit, and the "Dash 750," which re-integrated cruising amenities with a more modern aesthetic and rig.

Known Issues & Buyer’s Checklist

Prospective buyers of a Corsair 24 Mk II should focus their inspection on the mechanical components unique to trimarans and the high-stress areas of a performance hull.

• Folding System Hardware: The aluminum folding struts and their associated stainless steel mounting bolts are the most critical inspection points. Owners should look for signs of galvanic corrosion or elongated bolt holes, which can lead to "play" in the amas (outer hulls) while sailing.
• Compression Post & Mast Step: Given the high rig loads generated by the rotating mast and the lack of heeling, the area around the mast step and the internal compression post should be checked for cracks or structural deformation.
• Daggerboard Trunk: The trunk is a common site for impact damage if the boat has been grounded. Check for weeping or stress cracks at the base of the trunk inside the cabin.
• Core Integrity: While Corsair utilized vacuum-bagged construction, older hulls may suffer from moisture ingress in the deck or amas if hardware was not properly bedded. A percussion test (hammer sounding) is recommended for the flat sections of the amas.
• Rudder Blade and Gudgeons: The kick-up rudder is convenient for beaching but prone to wear in the pivot mechanism. Excess vibration at high speeds often points to worn bushings in the rudder head.

Community & Resources

The Corsair 24 Mk II is supported by a robust global network of enthusiasts. The most prominent resource is the Corsair Marine Community, which hosts technical forums and organized "Safaris"—long-distance cruising events specifically for trailerable trimarans. Additionally, the F-Boat community, though historically centered on Ian Farrier’s specific designs, remains a deep repository of technical knowledge for the structural maintenance of these folding systems.

The Verdict

The Corsair 24 Mk II is a premier choice for sailors who refuse to choose between high-performance racing and the ability to explore remote cruising grounds via a trailer.

Pros

• Exceptional speed and light-air performance.
• Easily trailerable, allowing for low-cost dry storage and expanded cruising ranges.
• The folding system is reliable and allows for standard marina slip access.
• High resale value due to a dedicated following and limited production numbers.

Cons

• Interior volume is cramped for extended stays with more than two adults.
• Initial purchase price is significantly higher than monohulls of the same length.
• The complexity of the folding system and rotating rig requires more maintenance than a fixed-keel boat.
