The Windex 92 is a 30-foot performance cruiser that serves as a vital piece of nautical history, representing the early engineering collaboration between Swedish aeronautical pioneers Lars Bergström and Sven-Olof Ridder. Produced by Radab AB (Research And Development AB) between 1981 and 1991, the boat was designed not merely as a family cruiser but as a primary platform for the B&R rig, a revolutionary mast design that would later become a hallmark of the American-built Hunter Marine line. While Radab is perhaps more widely recognized in aviation circles for the Windex 1200 motor glider, the Windex 92 successfully applied the firm's aerodynamic expertise to the water, resulting in a stiff, stable, and technologically advanced vessel for its era.

Sailing Performance & Handling
The defining characteristic of the Windex 92 is its rigging. As an early adopter of the B&R system, the boat features swept-back spreaders that create a tripod-like support structure for the mast. This configuration provides exceptional rig tension and allows for a smaller-diameter, more aerodynamic mast section. According to technical specifications provided by Windex Development, the design goal for their wind indicators—and by extension their hull designs—was sensitivity "as light as cigarette smoke." In practice, this translates to a boat that is remarkably responsive in light air.
With a ballast-to-displacement ratio of approximately 48%, the Windex 92 is exceptionally stiff. This high percentage of ballast, often concentrated in an iron swing keel or centerboard, allows the boat to carry its sail area deep into a breeze without excessive heeling. However, this stability comes with a trade-off in "sea-kindliness" in rougher conditions; anecdotal evidence from Swedish sailing forums suggests the hull can be quite wet in a head sea due to its relatively light displacement and hull shape. The swing keel version provides a versatile draft range of approximately 3.5 feet (keel up) to 6.6 feet (keel down), making it well-suited for both shallow Scandinavian archipelagos and deeper coastal reaches.
Interior Comfort & Variations
Despite its modest 30-foot (9.2-meter) length, the Windex 92 was marketed as a "Family Cruiser" with a surprisingly dense accommodation plan. Contemporary Swedish databases like Sailguide note that the interior was configured to sleep up to seven people—a feat achieved through a combination of a double V-berth forward, a convertible saloon, and clever use of quarter berths.
The interior finish reflects the Swedish craftsmanship of the 1980s, typically featuring warm mahogany or teak joinery. However, the vessel was designed with a focus on day-to-day sailing efficiency rather than long-term liveaboard luxury. The original specifications highlight relatively small fuel (11 gallons) and water (26 gallons) capacities, emphasizing that the boat was intended for coastal hopping rather than extended blue-water passage making. While no formal "4-cabin" variants exist due to the hull's size, some models featured slight variations in galley layout depending on the specific production year and owner requirements.
Known Issues & Buyer’s Checklist
Prospective buyers of a Windex 92 should focus their inspection on the unique technical elements that define the model:
- B&R Rig Tension: Because the rig relies on "pre-bend" and specific tensioning of the reverse-diagonal shrouds, the mast and chainplates should be inspected by a rigger familiar with B&R configurations. Improper tuning can lead to mast pumping or structural fatigue.
- Swing Keel Mechanism: The pivoting iron keel and its lifting tackle are prone to corrosion and wear. The pivot pin and the lifting cable should be checked for "play" or fraying to prevent a failure that could jam the keel in either position.
- Deck Core Integrity: Like many 1980s builds, the Windex 92 utilized balsa-cored decks. Buyers should use a moisture meter or percussion test around high-load areas like the mast step and winches to ensure no water ingress has softened the core.
- Engine Maintenance: Many units were originally fitted with small 8-hp to 15-hp Yanmar diesel engines. These are generally reliable but should be checked for exhaust elbow scaling and motor mount degradation.
Community & Resources
Due to its limited production run, there is no large international class association. However, the boat is well-supported within the Swedish sailing community. Technical data and historical context can be found through the Swedish Windex Development headquarters, which still operates as the primary manufacturer of the world-famous Windex wind indicators. Technical discussions often occur within broader Swedish "Segelbåt" (sailboat) groups, where the Windex 92 is discussed alongside other Bergström & Ridder designs.
The Verdict
The Windex 92 is an "engineer's sailboat," offering a unique blend of aeronautical design and classic Swedish boatbuilding. It is an ideal choice for the sailor who appreciates innovative rigging and a stiff, performance-oriented hull, though it may feel cramped for large families on longer voyages.
Pros:
- Innovative B&R rig allows for a simplified, backstay-less or high-performance setup.
- Exceptional stability due to a high ballast-to-displacement ratio.
- Shallow draft capability with the swing keel version.
- Historically significant design from world-renowned naval architects.
Cons:
- Limited fuel and water capacity for long-distance cruising.
- Interior can feel "busy" with the high number of berths in a 30-foot hull.
- Can be a wet ride in choppy coastal conditions.
- Rarity makes finding specific spare parts or model-specific advice more difficult.
