About the Junker 24

Designed by Sigurd Fr. Herbern and launched in 1978, this Danish sailboat represents solid Scandinavian craftsmanship from builder Holstebro Plastværk A/S. At 23.62 feet overall with an 18.47-foot waterline, the Junker 24 offers a practical size for both novice sailors and experienced cruisers seeking a manageable vessel. The boat's fractional sloop rig carries 245 square feet of sail area, providing adequate power while remaining easy to handle. With a displacement of 4,244 pounds and substantial ballast of 2,094 pounds, this fiberglass yacht delivers the stability expected from European design traditions. The fin keel with rudder on skeg configuration offers good tracking and maneuverability in varied conditions. Built for coastal cruising and weekend adventures, the Junker 24 suits sailors looking for a seaworthy pocket cruiser. Its 8.53-foot beam provides reasonable interior volume for its size, while the 4.10-foot draft allows access to many anchorages. The comfort ratio of 18.85 indicates a relatively quick motion in seas, typical of smaller boats, while the capsize screening value of 2.11 suggests good stability characteristics. Hull speed reaches 5.76 knots, appropriate for relaxed coastal passages and harbor exploration.

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
 15
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
 49.34
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
 300.7
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
 18.85
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
 2.11
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. 5.76 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. 562.94 pounds/inch
