Design Brief & Intent
The primary mission of the Stiletto 30 was to provide a high-performance coastwise racer-cruiser that could be easily managed by a small crew, sailed straight onto a beach, and disassembled for highway trailering. Peter Wormwood modified the original 27-foot hull lines by extending the sterns, increasing the overall beam, and ballooning the inboard cabin tops 4. These bubble cabins gave the Stiletto 30 significantly more interior volume than its predecessor, allowing it to function as a genuine weekender.
Unlike standard cruising catamarans of the era from European builders, which featured heavy fiberglass layups and fully bridgedeck-enclosed salons, the Stiletto 30 preserved an open-bridgedeck layout. It features a massive, self-bailing solid cockpit deck aft of the mast and a lightweight polypropylene mesh trampoline forward. This kept the center of gravity low and the boat exceptionally dry.
The interior accommodations are divided between the two narrow hulls. The space is Spartan but clean, typically featuring a teak-and-holly cabin sole in later versions, small galley counters with a compact sink, a portable stove, and sleeping arrangements for up to four adults on snug berths. High-end wood joinery is conspicuously absent to save weight, with the focus instead on lightweight composites, functional storage, and overhead ventilation provided by multiple deck hatches. It is a boat designed for the outdoor enthusiast—ideal for sail camping where the journey is fast and the destination is a remote, shallow anchorage 7.
Construction & Configuration
What truly sets the Stiletto 30 apart in the annals of boatbuilding is its highly sophisticated aerospace-grade construction. Until 1985, Force Engineering manufactured the hulls and bridgedeck using pre-impregnated epoxy fiberglass and Kevlar skins sandwiching a Nomex aramid honeycomb core. The entire assembly was vacuum-bagged and baked in a massive autoclave at 250 degrees Fahrenheit under constant pressure. This technique achieved an incredibly high strength-to-weight ratio, ensuring the structure remained remarkably rigid and virtually impervious to the flexing that plagued early multihulls. Furthermore, the trapped air within the Nomex honeycomb core provided positive buoyancy, rendering the boat virtually unsinkable. In 1986, to control escalating production costs, the builder transitioned the laminate schedule to a vinylester resin and foam core sandwich.
The underbody configuration features twin kick-up daggerboards in the hulls, replacing the single centerline centerboard of the standard Stiletto 27. This dual-board system, paired with transom-hung kick-up rudders, enables a minimum draft of just under ten inches with the foils raised 8. This makes the boat exceptionally beachable. Under sail, the fractional sloop rig is supported by a deck-stepped, rotating aluminum spar. Crucially, Wormwood chose a boomless mainsail design. By eliminating the boom, the main can be sheeted far aft on the wide rear traveler safely and efficiently, entirely removing the threat of a dangerous boom sweep during high-speed downwind gybes.
Sailing Performance & Handling
The Stiletto 30 behaves less like a traditional cruising catamaran and more like an scaled-up racing dinghy. With a design displacement of just 2,100 pounds, it is an exceptionally light platform for its nearly 30-foot length. This light weight is reflected in a Displacement-to-Length ratio of 48.54, which places the vessel firmly in the ultra-lightweight racer class. Coupled with a massive Sail Area-to-Displacement ratio of 39.02, the boat possesses a staggering amount of aerodynamic horsepower. In a moderate breeze, the Stiletto 30 accelerates with sports-car-like immediacy, easily sailing at or near wind speed on a reach.
At the helm, the twin rudders provide precise, highly responsive steering, though the boat requires active mainsheet trimming to manage its considerable power. In light air, the hulls can feel slightly sticky due to their wetted surface area, but once the wind builds and a hull begins to lighten or lift, the boat breaks free and flies.
The low Comfort Ratio of 2.54 indicates that the motion in a seaway is lively and rapid. The Stiletto 30 does not possess the heavy, motion-dampening momentum of a deep-keel monohull; instead, it rides over the waves rather than through them. While the motion is quick and can feel jerky in short chop, the boat sails flat, which dramatically reduces crew fatigue. The Capsize Ratio of 5.57 highlights the immense stability inherent in its wide, lightweight beam configuration, though like all high-performance catamarans, it demands vigilance in high winds to prevent pitchpoling when sailing hard downwind.
Known Issues & Maintenance Triage
While the high-tech Nomex and epoxy construction produced a structurally superior vessel, it presents unique maintenance challenges forty years after launch. The primary threat to the Stiletto 30 is water intrusion into the Nomex honeycomb core. Unlike closed-cell foam, honeycomb cells can act as tiny reservoirs if water penetrates the outer fiberglass skin. This typically occurs around poorly sealed deck hardware, stanchions, or aftermarket modifications. Once wet, freeze-thaw cycles can quickly cause extensive delamination and structural softening. Prospective buyers must conduct thorough moisture testing and tap-testing across all deck and hull surfaces.
The kick-up rudder cassettes and daggerboard trunks are also common high-stress areas. Beaching or hitting submerged obstacles at speed can crack the fiberglass trunks or bend the aluminum and stainless-steel rudder brackets. Additionally, the rotating mast base relies on a custom bearing system that requires regular rinsing and lubrication; salt buildup or neglect can cause the mast to bind, which increases load on the rigging and degrades sailing performance. Finally, the custom expanding trailer—designed to telescope the hulls inward to a legal trailering width—is prone to severe corrosion and seized telescoping arms if it has not been meticulously washed down with fresh water and greased regularly.
Modernization & Upgrades
Modern owners have found excellent success in modernizing the Stiletto 30 with contemporary marine technology. One of the most popular upgrades is replacing the heavy, original wire standing rigging with modern synthetic materials like Dyneema or Vectran, which dramatically reduces weight aloft and improves the boat's stability and motion.
The original fighter-jet-style plexiglass bubble canopies, which are highly prone to yellowing, crazing, and cracking from UV exposure, are frequently replaced. Some owners fabricate custom carbon fiber hatches to retain the iconic look, while others retrofit low-profile, modern Lewmar deck hatches for a cleaner aesthetic and better seals.
Auxiliary propulsion is another area ripe for modernization. Traditionally powered by a single, centrally mounted long-shaft outboard (typically 8 to 9.9 horsepower), many owners are transitioning to lightweight electric outboards. Because the hull is so easily driven and lightweight, a modern electric propulsion system offers more than enough thrust for harbor maneuvering and eliminates the weight, noise, and fuel-storage hassles of a traditional combustion engine.
The Verdict
The Stiletto 30 remains a masterclass in lightweight multihull engineering. It is a highly specialized boat, trading standing headroom and luxurious interior joinery for raw, unadulterated speed and the ability to explore knee-deep shallows. For the sailor who values the thrill of sailing at double-digit speeds and enjoys beach-camping style cruising, it represents an incredibly rewarding and historically significant platform. However, it requires a dedicated owner who understands the nuances of maintaining high-tech composites and is willing to actively manage a high-horsepower rig on the water.

- Highly advanced, rigid, and unsinkable Nomex honeycomb construction on older models
- Boomless rig eliminates the hazard of gybe impacts in a crowded cockpit
- Easily disassembled or telescoped on a specialized trailer for overland transport and winter storage
Cons:
- Spartan accommodations with limited headroom and no private cabins
- Highly vulnerable to expensive core delamination if water penetrates the Nomex honeycomb structure
- Lively, quick motion in a seaway can feel hyperactive compared to heavy-displacement cruising boats
- High-horsepower rig demands active sail handling and experience to sail safely in heavy weather
