About the Aloha 271

Designed by renowned naval architect Robert Perry and built by Canadian manufacturer Aloha Yachts starting in 1983, this 27-foot sailboat represents a thoughtful approach to compact cruising. Perry's design philosophy shines through in the boat's balanced proportions, featuring a fin keel with spade rudder configuration that provides responsive handling and efficient sailing performance. With a fractional sloop rig and moderate sail area of 343 square feet, the Aloha 271 offers manageable sail handling for couples or small crews while maintaining good light-air performance. The substantial ballast-to-displacement ratio contributes to confident stability, making this boat well-suited for coastal cruising and weekend adventures. Her fiberglass construction ensures durability and relatively low maintenance requirements. The boat's comfort ratio of 17.04 suggests a design optimized more for sailing performance than interior volume, typical of Perry's work during this era. The capsize screening formula of 2.18 indicates reasonable stability for coastal waters, though the boat is better suited for protected waters and day sailing rather than extended offshore passages. This design appeals to sailors seeking a well-mannered boat that rewards good technique while offering the reliability expected from both Perry's design legacy and Aloha's Canadian craftsmanship.

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
 18.34
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
 38.46
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
 203.8
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
 17.04
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
 2.18
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. 6.36 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
 2.81
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. 757.32 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. 18.35
