About the Jaguar 23 Tk

Designed by John Mullins and built by Jaguar Yachts Ltd. in the UK starting in 1983, this 23-footer represents a practical approach to small boat cruising with its distinctive twin keel configuration. The twin keel design allows the boat to dry out safely on beaches or in tidal harbors, making it particularly appealing for coastal exploration and gunkholing adventures where single-keel boats fear to tread. With a moderate displacement of 3,200 pounds and fractional sloop rig carrying 254 square feet of sail, the Jaguar 23 Tk strikes a reasonable balance between stability and performance for weekend coastal cruising. The twin keels provide excellent directional stability and reduced draft compared to a traditional fin keel design, though at some cost to windward performance. Her fiberglass construction ensures durability and relatively low maintenance. The comfort ratio of 14.44 suggests a relatively stiff, motion-conscious design suitable for day sailing and short coastal hops rather than extended offshore passages. Her capsize screening value of 2.22 indicates reasonable stability for coastal waters. The 8.16-foot beam provides adequate interior space for a boat this size, while the hull speed of nearly 6 knots offers respectable performance under sail for relaxed coastal cruising.

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
18.76
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
178.57
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
14.44
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
2.22
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. 5.99 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. 583.13 pounds/inch
