The Flying Cruiser A represents the foundational success of Sudplast (now BWC Illmensee), a German shipyard that became a staple of European lake and coastal sailing. Introduced in 1967 and designed by the prolific Heribert Streuer, the Flying Cruiser A was conceived as a "Wanderjolle"—a cruising dinghy—that offered the safety and storage of a cabin boat with the agility of a lightweight racer. Produced until 1975, it established a design language of "two-shell" construction, utilizing a GRP hull and deck with foamed cavities to ensure buoyancy. This "unsinkable" reputation, combined with a modest length of 5.12 meters (16.8 feet), made it an ideal entry point for families seeking a trailerable vessel that could be easily managed by a small crew or even single-handed.

Sailing Performance & Handling
The Flying Cruiser A is characterized by its masthead sloop rig and a remarkably light displacement of approximately 350 kilograms. This low mass, relative to its sail area (typically around 14 square meters), allows the boat to respond quickly to light puffs of wind, though it requires active weight management by the crew in gusty conditions. Because the boat features a centerboard rather than a fixed keel, it exhibits the lively handling of a large dinghy. Owners often note that while it can be "tender" (leaning easily) initially, its wide beam of 2.00 meters provides a secondary stability that provides confidence in moderate breezes.
The boat's draft is a mere 0.20 meters with the centerboard up, making it exceptionally "sea-kindly" for inland exploration and beaching. When the board is fully extended to 1.20 meters, the boat tracks reasonably well upwind, though like most centerboarders of this era, it does not point as high as a modern deep-keel racer. Technical reviews from the period, such as those found in archival German maritime evaluations, often highlight the boat's ability to plane under favorable downwind conditions, a feat rarely achieved by cabins boats of the late 1960s.
Interior Comfort & Variations
Despite its small footprint, the "A" model provides a surprisingly functional interior for its class. The cabin is often described as having "full seat height," meaning adults can sit upright on the berths without stooping—a critical feature for a 17-foot boat intended for weekend trips. The layout is minimalist, typically featuring two V-berths that extend under the cockpit seats, providing sleeping quarters for two adults.
The interior finish reflects the utilitarian standards of Sudplast, with the GRP inner shell providing a clean, low-maintenance environment. While it lacks a dedicated galley or head, the cabin serves as a dry "cuddy" for gear storage or a sanctuary from sudden weather changes. The Flying Cruiser A was built alongside the Flying Cruiser B, which shared the same hull but featured slight variations in deck molding and rigging to cater to different regional preferences. Later iterations, such as the Flying Cruiser S, expanded on this concept with more sophisticated interior appointments and an enclosed centerboard case to prevent water ingress into the cabin.
Known Issues & Buyer’s Checklist
When inspecting a Flying Cruiser A, the age of the vessel and its specific construction method require focused attention:
- Foam Core Saturation: The double-shell GRP construction uses foam for buoyancy. If the hull or deck has suffered cracks or unsealed through-hull fittings, water can migrate into the foam. This significantly increases the boat's weight, ruins its sailing performance, and is notoriously difficult to dry out.
- Centerboard Pivot and Trunk: The centerboard mechanism should be checked for corrosion and smooth operation. In older Sudplast models, the trunk can develop stress cracks near the pivot point, which may lead to leaks that are difficult to access due to the double-hull design.
- Rigging Attachments: Given the boat's age, the mast step and chainplates should be inspected for "crazing" in the fiberglass. While the hull is robust, decades of tension can cause the GRP to fatigue where the stays are anchored.
- Windows and Seals: The original rubber gaskets on the cabin windows are prone to UV degradation. Leaking windows can lead to moisture buildup between the shells, exacerbating the foam saturation issue mentioned above.
Community & Resources
The legacy of the Flying Cruiser A is maintained by a robust community of German and Central European sailors. BWC Illmensee continues to provide a degree of technical continuity, as they still manufacture the modern descendants of the Flying series, such as the Flying Cruiser F. Owners often congregate in regional sailing clubs or digital technical wikis dedicated to the "Flying" fleet to share restoration tips and rigging modifications.
The Verdict
The Flying Cruiser A remains a quintessential choice for sailors who prioritize trailerability and safety in a classic package. While it lacks the amenities of larger cruisers, its "unsinkable" build and responsive handling make it a timeless day-sailer.
Pros:
- Trailerability: Light enough to be towed by a standard passenger car and launched from a simple ramp.
- Safety: Unsinkable construction due to the foamed double-shell design.
- Shallow Draft: Ideal for exploring shallow lakes, rivers, and coastal flats.
Cons:
- Weight Sensitivity: Performance is highly dependent on crew positioning due to its light displacement.
- Water Infiltration: Potential for foam saturation in the double hull can be a "deal-breaker" if not caught early.
- Minimalist Accommodations: Best suited for day trips or "camping" rather than true cruising.
