About the Optima 98 Dehler

Designed and built by Dehler Yachts, this German-engineered sailboat represents the manufacturer's commitment to performance-oriented sailing. The Optima 98 emerged during an era when Dehler was establishing its reputation for creating boats that balanced racing capabilities with practical cruising features. With its sleek hull design and modern sailing characteristics, this vessel appeals to sailors seeking spirited performance on coastal waters. The boat's construction reflects Dehler's Germanic attention to detail and engineering precision, incorporating design elements that promote both speed and stability. The cockpit layout emphasizes sailing efficiency while maintaining comfort for crew and guests during extended outings. The Optima 98 suits sailors who appreciate responsive handling and enjoy active sailing experiences rather than passive motoring. Its design suggests capability for both weekend coastal cruising and club racing activities, making it versatile for owners with varied sailing interests. The boat's size positions it well for couples or small families wanting a manageable yet capable vessel. While detailed specifications remain limited, the Optima 98 carries forward Dehler's tradition of creating boats that reward skilled seamanship with excellent sailing performance, particularly in moderate to fresh wind conditions.

Performance Ratios
SA/Displacement Sail Area to Displacement ratio measures how much sail power a boat has relative to its weight. Higher values mean more performance and speed.
Under 14 — Heavy cruiser, slow14–18 — Cruising sailboat18–22 — Cruiser/racerOver 22 — Performance racer
19.82
Comfort Ratio Ted Brewer's Comfort Ratio predicts how comfortable a boat will feel in offshore conditions. Higher values mean a steadier, more comfortable motion in a seaway.
Under 20 — Uncomfortably rough20–30 — Acceptable coastal30–40 — Good offshore comfortOver 40 — Very comfortable offshore
23.52
Capsize Screening Formula The USHS Capsize Screening Formula estimates offshore capsize risk. Lower is safer — values under 2.0 are considered acceptable for offshore sailing.
Under 2.0 — Safe for offshore2.0–2.2 — Borderline offshoreOver 2.2 — Coastal use recommended
1.91
Hull Speed Hull Speed is the theoretical maximum speed of a displacement hull, calculated from waterline length. Most cruising sailboats reach this speed in moderate conditions. 6.78
Pounds/Inch Immersion Pounds per Inch Immersion (PPI) tells you how much weight is needed to sink the boat one inch. Useful for calculating how additional gear and stores affect waterline. 899.73
