About the Rh 43

Designed by renowned naval architect Ron Holland and built by Taiwan's respected Ta Chiao Shipbuilding, this 43-footer represents quality construction from the mid-1980s golden era of performance cruising yachts. Holland's signature design philosophy shines through in the balanced proportions and thoughtful engineering that made his boats sought-after on both racing circuits and cruising grounds. The masthead sloop rig and fin keel with rudder on skeg configuration deliver excellent sailing performance, while the robust fiberglass construction ensures durability for serious offshore passages. With a displacement of 23,780 pounds and ballast of 9,390 pounds, she strikes an appealing balance between stability and performance. The comfort ratio of 33.08 suggests a relatively stiff, performance-oriented design that won't pound excessively in a seaway, while the capsize screening formula of 1.81 indicates good offshore capability. This yacht excels as a serious bluewater cruiser with competitive sailing ability. The generous sail area of 860 square feet provides excellent light-air performance, while the substantial displacement offers the load-carrying capacity needed for extended cruising. Ta Chiao's reputation for quality construction, combined with Holland's proven design credentials, makes this an excellent choice for sailors seeking a capable offshore cruiser with racing pedigree.

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
 16.71
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
 39.49
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
 273.71
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
 33.08
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
 1.81
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. 7.80 kn
S# (Speed Number) The Speed Number (S#) is a quick performance index. Higher values indicate a faster, more powerful design relative to its size.
Under 3.0 — Slow cruiser3.0–5.0 — Average cruiser5.0–7.0 — Performance cruiserOver 7.0 — Racer
 1.93
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. 1,572.35 pounds/inch
SA/Displacement (Calc) Calculated Sail Area to Displacement ratio using actual measured sail dimensions rather than reported values. More precise than the reported SA/Disp figure. 16.62
