Dehler Optima 98 Information, Review, Specs

Sailing Performance & Handling

The Optima 98 is widely regarded as a stiff, sea-kindly vessel that excels in upwind tracking. Drawing from the design principles of Van de Stadt Design, the hull features a moderate displacement-to-length ratio that provides a sense of security in heavy weather, a characteristic often missing in lighter modern production boats. The boat’s performance is defined by its deep fin keel and a balanced spade rudder, which offers responsive steering even when heeled.

Under sail, the Optima 98 feels balanced; owners frequently report that the boat "finds its groove" easily and requires minimal helm correction once the sails are trimmed. While it lacks the explosive acceleration of modern carbon-reinforced Dehlers, its ability to maintain momentum through a chop is superior to many of its contemporary rivals. The fractional rig option—popular in northern European markets—allows for finer control over mast bend and mainsail shape, making it a favorite for club racing as well as coastal cruising.

Interior Comfort & Variations

The interior of the Optima 98 showcases Dehler's early commitment to maximizing functional living space within a 32-foot frame. The most common configuration features a traditional layout: a forward V-berth, a central salon with a folding table, a compact L-shaped galley to port, and a dedicated navigation station to starboard. One of the standout features of this model is the generous headroom, which reaches nearly 1.90 meters (approx. 6'3") in the main salon, a feat for a boat of this vintage.

Dehler produced several variants to suit different markets. The Optima 92 served as the base hull, but the Optima 98 provided a more sophisticated finishing. While the Optima 92 often featured more basic interior modules, the 98 frequently utilized higher-quality wood veneers and integrated storage solutions that paved the way for the later Optima 101 and 106 models. The "GS" variant often included upgraded upholstery and additional electronics at the helm, aimed at the more discerning cruiser. Because the 98 is a direct sibling to the 92, many parts—including the mast, boom, and much of the interior cabinetry—are interchangeable, though the 98’s extended stern provides a larger cockpit and better access to the water.

Known Issues & Buyer’s Checklist

Prospective buyers of a Dehler Optima 98 should approach the vessel with an understanding of its age, focusing on the following technical areas:

• Deck Core Integrity: Like many boats of the era, Dehler utilized a balsa-core sandwich construction for the decks. It is critical to inspect for soft spots, particularly around the chainplates, stanchion bases, and the mast step, where water ingress can lead to core rot.
• Original Engines: Many Optima 98s were originally fitted with Farymann or early Yanmar diesel engines. While robust, parts for Farymann units are increasingly difficult to source. Buyers should prioritize hulls that have undergone a "re-powering" with a modern Volvo Penta or Yanmar saildrive.
• Rudder Bearing Wear: The spade rudder is a high-performance feature but is prone to developing "play" in the bearings over decades of use. Check for vibration or knocking sounds while the boat is under power or in a swell.
• Keel-to-Hull Joint: Inspect the internal "floors" and keel bolts for signs of weeping or rust. While Dehler’s construction is generally robust, the age of the sealant in the keel joint may require a "drop and re-bed" if any movement is detected.

Community & Resources

The Optima 98 benefits from a highly active owner community, largely centered in Northern Europe. The most prominent technical resource is the Dehler Club, a multi-national organization that hosts technical wikis and historical documentation for the Optima and Delanta series. Additionally, because the boat was designed by E.G. van de Stadt, technical drawings and rig specifications are often preserved in the designer’s archives, providing a level of support rarely found for yachts of this vintage.

The Verdict

The Dehler Optima 98 is a robust, well-engineered cruiser that offers a "big boat" feel in a manageable 32-foot package. It remains an excellent choice for sailors who prioritize structural integrity and sailing sensations over the voluminous, apartment-like interiors of modern wide-beam cruisers.

Pros:

• Exceptional build quality and "sea-kindly" hull design by Van de Stadt.
• Strong upwind performance and tracking.
• Generous headroom for a vessel under 10 meters.
• Active owner community and availability of historical technical data.

Cons:

• Aft-cockpit can feel cramped with more than four adults.
• Original Farymann engines are difficult to maintain.
• Potential for deck core issues if hardware has not been re-bedded.
• Narrow beam compared to modern standards limits lateral interior space.
