About the Mirage 27 Perry

Designed by renowned naval architect Robert Perry and built by Canada's Mirage Yachts Ltd. beginning in 1982, this 28-footer represents a compelling blend of performance and practicality for coastal cruising and club racing. Perry's signature design philosophy shines through in the boat's balanced proportions, featuring a modern fin keel with spade rudder configuration that delivers responsive handling and solid upwind performance. With a displacement of 5,200 pounds and 2,200 pounds of ballast, the Mirage 27 Perry strikes an appealing middle ground between lightweight performance and seaworthy stability. The masthead sloop rig carries 313 square feet of sail area, providing spirited performance in moderate conditions while remaining manageable for short-handed sailing. Her 21.67-foot waterline length translates to a theoretical hull speed of 6.24 knots, making her competitive in PHRF racing while offering respectable passage-making ability. The fiberglass construction ensures durability and lower maintenance compared to wooden alternatives of the era. Perry's design expertise, honed through decades of creating successful racing and cruising boats, is evident in the boat's reputation for solid construction quality and predictable sailing characteristics. This combination makes the Mirage 27 Perry an excellent choice for sailors seeking an affordable entry into serious coastal sailing and weekend racing.

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
 16.73
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
 42.31
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
 228.13
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
 17.63
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
 2.14
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. 6.24 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
 2.37
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. 716.22 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. 16.74
