The Iceni 39 (often marketed as the i39) is a British-built, high-performance monohull designed by naval architect Henry Bateson and produced by Iceni Yachts. Developed with a primary focus on IRC racing and offshore speed, the vessel was conceived to offer "performance without compromise," targeting the competitive racer-cruiser market. Launched in the early 2010s, the model is built in the East of England, a region with a deep-seated boat-building heritage. Unlike many mass-production cruiser-racers that lean heavily toward interior volume, the Iceni 39 prioritizes a lightweight, high-stiffness hull form and a refined sail plan, making it a "weapon" on the racecourse that remains capable of fast passage-making.

The model is most famously represented by the prototype Andrasta, an offshore racer that has actively competed in RORC and UNCL circuits, including the Fastnet Race. The builder offers the yacht in three distinct configurations to suit different sailing profiles: the Club Racer (CR), the Offshore (OS), and the Grand Prix (GP). While the core hull remains consistent, these variants differ in their mast specifications (carbon vs. aluminum), foil optimization, and interior fit-out levels, allowing owners to tailor the boat to either weekend racing or serious transoceanic competition.
Sailing Performance & Handling
The Iceni 39 is defined by a modern, slippery hull with a high Sail Area-to-Displacement (SA/Disp) ratio, placing it firmly in the high-performance category. With a displacement of approximately 5,600 kg (12,346 lbs) and a generous sail area of nearly 88 square meters (945 sq ft), the boat is exceptionally responsive in light airs but truly excels when powered up on a reach. Its technical profile—featuring a deep 2.5-meter (8.2 ft) fin keel with a lead bulb and a balanced spade rudder—provides the necessary righting moment to carry a large rig while maintaining precise tracking.
Handling is sharp and communicative, characteristic of a yacht designed by an America’s Cup-connected technical team. According to Iceni Yachts, the design incorporates advanced Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA) to ensure that the foils are as efficient as possible. On the water, this translates to a boat that "bites" well upwind and can be pushed hard downwind with minimal risk of rounding up. The rig is typically a fractional sloop with a significant "P" (main luff) dimension, often paired with high-tech sails to maximize the IRC rating efficiency. Owners of the Offshore (OS) variant frequently note the boat's ability to maintain high average speeds in offshore swells without the "skittish" feeling common in lighter, ultra-thin hulls.
Interior Comfort & Variations
The interior of the Iceni 39 reflects its performance pedigree: it is functional, weight-conscious, and stylishly minimalist. While it provides the necessary amenities for offshore racing and limited cruising, it avoids the heavy cabinetry and plush moldings found in luxury cruisers. The layout typically features a bright, open saloon with white bulkheads and lightweight composite finishes, which helps keep the center of gravity low and the overall displacement within racing specs.
Configuration varies by sibling model:
- Grand Prix (GP): The most spartan version, often featuring pipe cots and minimal galley equipment to save weight for professional-level racing.
- Offshore (OS) and Club Racer (CR): These variants provide a more "civilized" experience, usually including a double V-berth forward, settee berths in the saloon, and additional sleeping quarters aft. The galley is equipped with the basics for coastal or offshore hops, including a small sink and stove.
Headroom is adequate for a performance boat of this length, though the focus is clearly on ergonomics for a working crew rather than social lounging. Large hull windows provide visibility and natural light, preventing the "cave" feeling common in older racing designs.
Popular Mentions & Media
The Iceni 39’s primary claim to fame in the nautical media is the Andrasta Race Team. As the flagship for the brand, Andrasta has been a regular fixture in the RORC (Royal Ocean Racing Club) offshore series, serving as a platform to prove the boat's durability and speed. The yacht has been featured in technical discussions regarding IRC optimization and modern British yacht design in European racing publications.
Known Issues & Buyer’s Checklist
Prospective buyers of a used Iceni 39 should approach the purchase with a "racing survey" mindset. Because these boats are often campaigned hard, several technical areas require scrutiny:
- Keel and Rudder Attachments: Given the high loads generated by a 2.5-meter draft and a bulb keel, the internal grid and keel bolts should be inspected for any signs of stress or movement, especially if the boat has a history of groundings during racing.
- Rigging Fatigue: High-performance rigs (especially the carbon Selden options found on many i39s) require rigorous standing rigging inspections every few years. Look for signs of "panting" or stress cracks around the chainplates.
- Electronics Integrity: Racing yachts often have complex, integrated B&G or Raymarine systems with multiple mast-head and hull sensors. Ensure all NMEA 2000 or similar networks are functioning without intermittent data loss.
- Composite Finish: While the foam-sandwich construction is robust, look for "star" cracks in the gelcoat around high-load areas like winch bases and the cockpit sole, which may indicate flex or heavy winch usage.
Community & Resources
The primary resource for technical data and factory support remains the builder, Iceni Yachts, based in Bressingham, UK. Because of the boat's niche, high-performance nature, there is no large-scale owner association; however, the racing community around the RORC and the UK offshore circuits serves as an informal network for sharing tuning tips and sail plan optimizations.
The Verdict
The Iceni 39 is a specialist's tool—a high-caliber racer-cruiser that trades "living room" comfort for raw speed and tactical precision.
Pros:
- Excellent power-to-weight ratio and light-air performance.
- Optimized for IRC racing, making it a competitive choice for offshore trophies.
- High-quality British engineering and advanced composite construction.
- Commendable tracking and stability for a lightweight monohull.
Cons:
- Spartan interior may not satisfy those looking for a traditional "family" cruiser.
- Deep draft (2.5m) limits access to some shallower coastal harbors and marinas.
- Higher maintenance requirements for the high-spec rig and foils.
