The Cayman 28, often heralded as the "Gentleman’s Skiff," is a highperformance, allcarbon sportsboat designed by the acclaimed naval architect Mark Mills. Originally commissioned as a bespoke oneoff for a client based in the Cayman Islands, the design has since transitioned into semiseries production through Code Yachts in Hungary. This vessel represents a modern evolution of the sportsboat category, blending the raw speed and technicality of a highperformance dinghy with the stability and scale of a 28foot keelboat. Its construction is uncompromising, utilizing epoxyinfused carbon fiber for the hull, deck, and structural components to achieve an incredibly light displacement of approximately 1,100 kg (2,425 lbs).

Sailing Performance & Handling

The sailing characteristics of the Cayman 28 are defined by its extreme technical ratios, which place it firmly at the top of the sportsboat hierarchy. With a Displacement/Length (D/L) ratio of 52.23 and a Sail Area/Displacement (SA/Disp) ratio of 44.38, the boat is exceptionally "supercharged." According to reports from Yachting World, the boat is capable of maintaining speeds in excess of 20 knots, even in moderate conditions.

Handling is characterized by its "skiff-like" agility but with the added security of a 400 kg (880 lb) lead bulb keel. The rig is a modern, no-backstay configuration with a large square-top mainsail, allowing for a simplified deck layout that eliminates the need for complex runners or backstays. A notable feature is the use of extendable "racks" or outriggers that slide out to provide a beam of 3.9 meters (12' 10"), significantly increasing righting moment without the need for trapezes. Sailing Magazine notes that while the boat is stiff and stable at the dock, it responds instantly to helm input and sail trim, making it a "Jekyll and Hyde" vessel that can be sailed in a relaxed "daysailer mode" with racks retracted or as an aggressive racer when fully extended.

The Cayman 28 gained significant international attention following the launch of Hull #1, named Rooster. The boat’s debut was particularly memorable when it participated in the 96-mile Blue Riband race on Lake Balaton, Hungary—an event with over 600 starters—where it successfully competed alongside much larger 40-foot racing yachts. The model has been featured as an "Extraordinary Boat" in Yachting World and was extensively reviewed by renowned designer Robert H. Perry in Sailing Magazine. Its presence at West Highland Week in Scotland further cemented its reputation as a versatile and "sexy" high-performance design capable of handling diverse racing environments.

Known Issues & Buyer’s Checklist

  • Winch Selection: Early versions were designed to be winch-less, relying on coarse and fine-tune purchases for the main and jib. However, feedback from racing teams suggests that the addition of small snubber winches (such as Harken Snubbairs) on the racks is highly beneficial for managing asymmetric spinnaker sheets in high-load conditions.
  • Stanchion and Rack Ergonomics: While the racks are designed for comfort, some owners have noted that the pressure from carbon stanchions during long periods of hiking can be intense. Modern hulls typically include sockets for webbing straps to improve crew comfort.
  • Draft Considerations: The standard T-keel has a deep draft of 1.92 meters (6' 4"). For owners in "skinny" water regions like the Sound in Grand Cayman, a shallow-keel variant (1.67m / 5' 5") exists, which should be verified during the purchase process to ensure it matches the local sailing environment.
  • Carbon Component Inspection: Given the high-modulus carbon construction and the use of carbon locks for halyards (AlphaLocks), buyers should inspect the rig and deck hardware for any signs of point-loading wear or stress cracking, which can occur in high-performance racing environments.

Community & Resources

Owners and prospective buyers primarily interface through Mills Design, the naval architecture firm responsible for the project. Technical support and manufacturing details are handled by Code Yachts in Hungary, who maintain the class standards and construction records. While not a large one-design class yet, the boat shares a design lineage with the Cape 31, and many owners draw technical inspiration and setup data from that established racing community.

The Verdict

The Cayman 28 is a specialist’s machine, offering near-foiling speeds in a conventional (non-foiling) monohull package.

Pros:

  • Exceptional speed-to-length ratio, easily exceeding 20 knots.
  • Ultra-modern carbon construction that allows for containerization (fits in a 40ft container).
  • Simplified deck and rig layout makes it surprisingly manageable for a small crew.
  • Stunning aesthetic that bridges the gap between classic "gentleman" styling and futuristic racing tech.

Cons:

  • High entry cost reflecting its all-carbon, high-tech specification.
  • Lacks any interior accommodations, limiting its use to pure daysailing or racing.
  • Deep draft can be restrictive in many popular coastal cruising or racing areas.
