About the Diamant 2000

Danish designer Jan Kjaerulff created this compact 24-footer as a modern coastal cruiser that balances performance with livability. Built by German manufacturer Ott Yacht GmbH starting in 1988, the Diamant 2000 features contemporary design elements that were progressive for its era, including a fin keel with bulb and spade rudder configuration that maximizes sailing efficiency while maintaining excellent maneuverability in tight quarters. With a displacement of 2,425 pounds and 926 pounds of ballast, this fractional sloop offers reassuring stability for coastal cruising and weekend adventures. The sail area-to-displacement ratio of 24.79 indicates spirited performance in moderate conditions, while the hull's 18.86-foot waterline length contributes to a theoretical hull speed of 5.82 knots. The comfort ratio of 11.12 suggests this boat favors performance over heavy-weather comfort, making it ideal for day sailing and coastal cruising rather than extended offshore passages. The Diamant 2000's 8.20-foot beam provides reasonable interior volume for overnight accommodation, while the 4.10-foot draft allows access to shoal waters and smaller harbors. This versatile design appeals to sailors seeking a responsive, well-mannered boat for exploring coastal waters with occasional short-handed sailing capability.

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
 24.79
Ballast/Displacement Ballast to Displacement ratio shows what percentage of the boat's total weight is ballast. Higher values generally mean better initial stability and stiffer sail carrying.
30–35% — Typical cruiser35–45% — Stiff performance boatOver 45% — Racing oriented
 38.19
Displacement/Length Displacement to Length ratio measures how heavy a boat is relative to its waterline length. Lower values mean a lighter, faster boat.
Under 100 — Ultralight racer100–200 — Light cruiser/racer200–300 — Moderate cruiser300–400 — Heavy cruiserOver 400 — Very heavy
 161.38
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
 11.12
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
 2.44
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. 5.82 kn
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. 552.59 pounds/inch
