Design Brief & Intent
The core mission of the Sunbeam 20 was to provide a "pocket luxury" experience. While many builders in the 20-foot range minimized interior fit-out to save weight and cost, Schöchl utilized their historical woodworking expertise to deliver a surprisingly upscale cabin. By omitting restrictive structural bulkheads, Nissen created an open-plan layout that maximizes the visual and physical space within the hull. The interior features Sapeli mahogany joinery and a level of finish quality that easily outclasses mass-market production competitors of its era.
The boat was targeted at couples transitioning down from larger cruising yachts who refused to sacrifice craftsmanship, as well as dinghy sailors looking for a dry, stable platform with overnight capabilities. It is built utilizing hand-laid fiberglass laminate—a hallmark of Schöchl's uncompromising approach to structural integrity. This robust layup ensures a stiff, durable hull capable of absorbing the stresses of regular trailering and launching.
Variations & Configurations
To suit various local regulations and waterway depths across Europe, the Sunbeam 20 was offered with multiple underbody configurations. The primary version features a fixed wing keel, which optimizes lift and keeps the center of gravity low while maintaining a relatively shallow draft. This configuration provides a highly stable, reassuring ride for families and less experienced crews.
For sailors navigating extremely shallow inland lakes or those who prioritize frequent ramp-launching, Schöchl also offered a swing-keel (keel-sword) option. Rigging on the Sunbeam 20 is remarkably modern for its class, featuring a fractional sloop configuration with a backstay-less B&R (Bergström & Ridder) rig. This eliminates the need for a backstay, allowing the boat to carry a mainsail with a generous, high-roach power head. Under the deck, the slip-cabin layout includes up to four berths (a double V-berth forward and two single quarter-berths), basic storage cubbies, and space for a portable chemical toilet.
Sailing Performance & Handling
On the water, the Sunbeam 20 behaves more like a spirited sportboat than a sluggish pocket cruiser. With a light displacement of 2,161 pounds and a displacement-to-length ratio (Disp/LWL) of 139.99, the hull is exceptionally slippery and accelerates quickly in light air. This lively nature is further emphasized by its aggressive sail area-to-displacement ratio (SA/Disp) of 26.99. The highly powered sail plan, combined with the lack of a backstay, allows the boat to point high and perform beautifully on off-wind legs, particularly when paired with an asymmetrical spinnaker or gennaker flown from a bowsprit.
At the same time, the boat maintains a respectable ballast-to-displacement ratio of 36.74%, giving it the necessary stiffness to carry its sail plan safely into moderate breezes before needing a reef. It is important to note that with a capsize screening formula of 2.54 and a motion comfort ratio of 10.3, the Sunbeam 20 is firmly a light-displacement daysailer. It will feel lively and active in a seaway, and it is not intended for offshore passages or rough, open-ocean conditions. However, on flat-water lakes or sheltered bays, the helm is balanced, responsive, and incredibly rewarding to sail.
Market Snapshot & Economics
Because Schöchl Yachtbau focused on build quality over mass production, the Sunbeam 20 was significantly more expensive than its contemporaries when new, and it continues to command a pricing premium on the European used market. These boats are relatively scarce outside of Central Europe, with most brokerage listings concentrated around German, Austrian, and Swiss lakes.
For prospective buyers, the economics of purchasing a used Sunbeam 20 are highly favorable due to the boat’s excellent depreciation resistance. Because the hull is solidly built and the rig is simple, maintenance costs are minimal compared to larger cruiser-racers. When inspecting a used model, buyers should pay close attention to the condition of the trailer, the pivot bolt and lifting mechanism on swing-keel variants, and any signs of wear on the chainplates of the highly swept B&R rig.
The Verdict
The Sunbeam 20 is a beautifully built, high-performance pocket cruiser that successfully bridges the gap between sporty lake racers and weekend family cruisers. It sacrifices absolute interior volume and standing headroom in exchange for gorgeous joinery, excellent sailing dynamics, and effortless trailerability. For the sailor who values Austrian engineering and premium finishes over raw accommodation space, it remains one of the finest 20-footers of its generation.
