About the Islander 34 2

Designed by renowned naval architect Robert Perry, this sophisticated cruiser represents the final evolution of Islander Yachts' popular 34-foot platform. Built from 1983 to 1985 with just 16 hulls completed, the Islander 34 2 combines Perry's signature performance-oriented design philosophy with practical cruising amenities. The fiberglass hull features modern Divinycell core construction for optimal strength-to-weight ratio, while the fin keel and spade rudder configuration delivers responsive handling and excellent windward performance. With a displacement of 9,656 pounds and 3,771 pounds of ballast, this masthead sloop offers reassuring stability for coastal cruising and capable offshore passages. Perry optimized the design for serious sailors seeking both comfort and performance. The generous sail area of 545 square feet and SA/Displacement ratio of 19.29 provide spirited sailing in light to moderate conditions, while the substantial displacement ensures steady motion in seaway. The moderate beam of 11 feet maximizes interior volume without compromising seaworthiness. The comfortable 20.47 comfort ratio and conservative 2.07 capsize screening value reflect the boat's suitability for extended cruising. With its proven Perry pedigree and quality Islander construction, the 34 2 appeals to discerning sailors who appreciate thoughtful design execution in a rare, well-built package.

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
 210
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
 19.29
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
 39.05
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
 196.37
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
 20.47
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
 2.07
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. 7.09 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
 2.71
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. 1,100.52 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. 16.68
