About the Aphrodite 34

Designed by Carl Beyer and built by Swedish manufacturer Rex Marin from 1976 to 1985, this well-proportioned 34-footer represents solid Scandinavian craftsmanship from the height of the fiberglass production era. The Aphrodite 34's moderate proportions and traditional fin keel with rudder-on-skeg configuration create a balanced platform that appeals to cruising sailors seeking both comfort and performance. With a displacement of 12,125 pounds and ballast ratio supporting confident stability, this masthead sloop demonstrates the thoughtful design philosophy typical of Swedish builders. The hull's lines generate a respectable hull speed of 7.20 knots, while the generous beam of nearly 11 feet provides comfortable interior volume without compromising seaworthiness. Her comfort ratio of 25.81 suggests a motion that favors longer passages over pure speed, making her well-suited for coastal cruising and weekend adventures. The sail area to displacement ratio of 16.73 indicates moderate power that won't overwhelm less experienced crews, yet provides adequate performance in light to moderate conditions. The capsize screening value of 1.89 reflects good initial stability characteristics. This Swedish design embodies the practical cruising philosophy of its era, offering reliability and comfort for sailors prioritizing seaworthiness over racing performance.

Performance Ratios
PHRF Rating PHRF (Performance Handicap Racing Fleet) is a national racing handicap measured in seconds per nautical mile. Lower values indicate faster boats. Ratings are sourced from US Sailing's national database (median across 60+ regional fleets).
Under 0 — Ultralight racer0–90 — Performance racer90–150 — Cruiser/racer150–210 — Typical cruiserOver 210 — Heavy/slow cruiser
141
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
16.73
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
38.68
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
224.95
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
25.81
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
1.89
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. 7.20 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
2.4
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. 1,116.14 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. 16.73
