Design and Construction
The hull is solid fiberglass and, as a consequence of that material, requires only a minimum of maintenance during the sailing season. The 42 DS holds CE certification as Class A (OCEAN), and it is designed for extended voyages where conditions may exceed wind force 8 and significant wave heights of 4 m and above but excluding ab. The capsize screening value is 1.91, a figure that by the formula alone would permit the boat to be accepted to participate in ocean races. With a length-to-beam ratio of 2.91, the design is more spacious than 90% of all other similar sailboat designs, and the displacement-length ratio of 249.85 places it among heavier cruisers, with 82% of comparable designs categorized as heavier per the cited assessment.
Rig and Handling
The standing and running geometry of the deck plan is documented in sheet estimates that reveal a working cockpit scale suited to the boat's size. The jib and genoa sheets are each estimated at 12.8 m (42.1 feet) with a 14 mm (0.55 inch) diameter, while the mainsheet runs 32.0 m (105.2 feet) at the same diameter, and a spinnaker sheet is estimated at 28.2 m (92.5 feet), also 14 mm. These lengths speak to a rig that demands proper lead angles and winch capacity rather than improvised trimming. The theoretical maximal hull speed of a displacement hull of this length is 8.12 knots, and the immersion rate of about 371 kg/cm (alternatively 2080 lbs/inch) means that loading 371 kg sinks the boat 1 cm, or 2080 lbs sinks it 1 inch — a quantifiable measure of how payload translates directly into loaded draft and waterline behavior on a hull of this volume.
Accommodations
Below, the Sunbeam 42 DS is equipped with 4 berths and carries a fresh water capacity of 570 liters (150 US gallons, 125 imperial gallons). The interior volume implied by the 2.91 length-to-beam ratio gives the boat a spatial advantage over the large majority of similar designs, and the 151-gallon water tank supports the extended-voyage brief encoded in its Class A certification. The Motion Comfort Ratio is 32.16, and comparison with similar sailboats shows the 42 DS is more comfortable than 46% of all similar sailboat designs — a middle-of-the-pack ride rather than a pillow-soft passage maker, consistent with its displacement-length profile.
Known Issues
The documented record for the Sunbeam 42 DS contains no reported structural defects, systemic failures, or owner-recurrent faults. The source material instead quantifies behavior rather than faults: the immersion and comfort ratios, the certificated ocean envelope, and the maintenance-light fiberglass hull. A buyer or reviewer working from authority documents will find the known-issue column effectively empty, with the only cautions being the predictable ones of any 1996–2007 GRP cruiser-racer — none specific to this model are stated in the source material.
Refits and Ownership
Ownership of a 42 DS built across an eleven-year run means engaging with a boat whose core facts are stable: solid fiberglass hull, lead ballast, and a rig whose sheet spec is fixed by design. The maintenance minimum of the fiberglass hull during the season lowers recurring labor, and the CE Class A rating preserves the boat's relevance for offshore intent regardless of subsequent equipment changes. With only twenty-nine built, the model remains a comparatively scarce J&J-designed Schöchl product rather than a high-volume platform.
The Verdict
The Sunbeam 42 DS is a certificated ocean-capable, J&J-designed Austrian cruiser-racer of notably efficient space and light-racer displacement, with a maintenance-light solid fiberglass hull and a documented absence of model-specific defects. Its comfort ratio is unremarkable against peers, but its spatial and weight metrics are distinctive.
Pros
- CE Class A (OCEAN) certification for extended voyages beyond wind force 8 and 4 m seas
- More spacious than 90% of similar designs by length-to-beam ratio (2.91)
- Capsize screening value of 1.91, admissible to ocean races by that formula
- Solid fiberglass hull requiring minimum seasonal maintenance
- Displacement-length ratio showing 82% of peers heavier
Cons
- Motion Comfort Ratio places it above only 46% of similar designs
- Only 29 built, limiting fleet support and resale comparables
- Documented sheet diameters and lengths imply a rig demanding full-size winch and lead infrastructure
