Design and Hull Character
Designed by van de Stadt, the 35 CWS carries a bulb fin keel and spade rudder configuration that telegraphs its performance intentions immediately. At 10.5 metres on deck with a waterline of 9.2 metres, the hull is notably long on the water relative to its overall length, a trait that feeds directly into potential hull speed and pointing ability. The hull itself evolved from the 36 CWS platform but runs somewhat narrower and longer on the waterline, a deliberate refinement that sharpened the sailing lines at the expense of interior volume. Construction is GRP with balsa core sandwich throughout hull and deck, an approach that keeps displacement honest — the boat tips the scales at around 4,800 to 5,100 kg depending on specification — and supports the light-displacement character the van de Stadt lines imply.
A displacement-to-length ratio of 190 places the 35 CWS firmly in light-displacement territory, meaning that cruising owners who load her with heavy ground tackle, spare parts, and provisioning will notice a measurable softening of performance. This is not a criticism so much as a characteristic: the design was optimised for crisp sailing, and sailors who respect that will get the best from her.
Rig, Sail Plan, and the Central Winch System
The defining engineering feature of the CWS range is the Central Winch System, a worldwide-patented Dehler arrangement that allows the helmsman to operate all halyards and sheets from the cockpit. In the 35 CWS, however, the self-tacking jib of the 36 CWS was replaced by an overlapping headsail, which necessitated two winches rather than one; the original genoa also carried a soft vertical batten to improve set when rolled. The practical effect is that short-handed sailing remains genuinely viable, but the elegance of the single-winch solution found on the 36 is diluted somewhat by the demands of the larger, overlapping sail plan.
The fractional sloop rig, paired with a sail area-to-displacement ratio of 19.6, means the boat will find her pace readily in moderate conditions and will satisfy the performance expectations of most cruising sailors without demanding heroic sail-handling. A ballast-to-displacement ratio of 40 percent gives reasonable initial stability, though the numbers suggest she will announce the need for a reef in the main before conditions become truly uncomfortable rather than after.
Accommodation and Below-Decks Layout
Below decks, the 35 CWS offers a conventional aft-cockpit cruiser layout with a forward double cabin, a separate aft cabin, and a saloon that converts two facing settees into additional berths — total capacity for up to six people across two separate cabins and the saloon. The forward cabin includes a double berth, hanging locker, and under-berth stowage, with an opening hatch and portholes providing ventilation; the aft cabin mirrors this arrangement.
Yachting Monthly's assessment cuts through the marketing language with useful candour: the saloon is traditional and on the small side, a reflection of the narrower beam relative to the 36 CWS. The outward-facing chart table is only moderately successful — an unusual choice that works better in theory than in practice for navigators who prefer to face the instruments rather than the companionway ladder. The galley lacks stowage, a genuine limitation for extended passages, though the forecabin can be reconfigured as an office or children's day cabin with fold-up table and bench seats, which adds meaningful flexibility for liveaboard or family use.
The galley as fitted carries a two-burner stove with oven, hot and cold water, and refrigerator, while the navigation station is equipped with an integrated instrument panel. The cockpit features teak on seats and sole, and the wheel steering console integrates the instrument display within easy reach of the helmsman.
Seakeeping and Passage-Making Character
The capsize screening formula of 1.9 places the 35 CWS below the critical threshold of 2.0, which is the conventional benchmark for offshore safety: the boat is, by this measure, a safer choice for passage-making than a significant proportion of production cruisers in her size range. The counterweight is the comfort ratio of 22.3, which Brewer's formula associates with the motion of a coastal cruiser with moderate stability — not an encouraging figure for those prone to seasickness on longer passages in confused seas.
The picture that emerges is of a boat designed for performance coastal and short-offshore work rather than sustained bluewater passages. She will handle a Channel crossing or a Baltic season with distinction; owners contemplating extended ocean passages should manage expectations around motion comfort in heavy weather.
Known Issues and Ownership Considerations
The balsa core sandwich construction of hull and deck that keeps the 35 CWS light also demands vigilance at deck hardware penetrations: any fastening that allows moisture ingress risks core delamination, a well-documented failure mode for this construction method across the production era. Pre-purchase surveys should probe the deck methodically around chainplates, stanchion bases, and any non-original fittings.
The outward-facing chart table is a design choice that owners frequently modify or work around. The galley stowage limitations are structural rather than incidental and represent the most common practical complaint from those sailing the boat offshore — a clever refit adding drawers beneath the nav station and on the outboard galley bulkhead addresses this meaningfully.
The Central Winch System, while ingenious, introduces electrical and mechanical complexity that ageing examples may present as a maintenance obligation. Prospective buyers should confirm the system is fully operational and that service history for the winch mechanism is available, as replacement parts for the original Dehler-specific hardware can be difficult to source.
Refits and Upgrades
Because the 35 CWS was built in modest numbers by a quality-oriented German builder, the structural foundation for a thorough refit is generally sound. The most productive upgrades focus on the areas Yachting Monthly identified as weak: improving galley stowage, addressing the chart table ergonomics, and upgrading the standing rigging if it has not been renewed within a reasonable service interval. The balsa core deck construction rewards a proactive inspection of all deck hardware with appropriate core remediation where moisture has penetrated.
Running rigging led aft to the cockpit in line with the CWS philosophy benefits from modern high-modulus lines if original ropes remain — the lower stretch dramatically improves control at the helm. The fractional rig responds well to carbon-fibre boom replacement as a weight-aloft reduction. Below decks, a lithium house bank paired with solar or wind generation transforms the boat for extended independent passages without touching the fundamental character of the design.
The Verdict
The Dehler 35 CWS is a thoughtful, well-engineered German fractional sloop that rewards sailors who value performance and short-handed handling over maximum interior volume. Van de Stadt's refined hull is quick and responsive, the patented Central Winch System remains a genuinely useful innovation, and the below 2.0 capsize screening figure gives reasonable confidence for coastal offshore work. The narrow beam that sharpens her sailing also constrains the saloon and galley in ways that passage-making crews will notice, and the chart table ergonomics represent an unfulfilled design ambition. She is not a blue-water go-anywhere cruiser, but as a performance yacht for coastal and short-offshore use she is compelling.

Cons
- Saloon is traditional and on the small side relative to the overall length
- Galley stowage is limited — a genuine constraint for extended offshore provisioning
- Chart table orientation is only moderately successful ergonomically
- Light displacement penalises performance under heavy cruising loads
- CWS mechanical and electrical system demands active maintenance on older examples
