About the Mirage 55

Designed by Ken Fickett and produced by Mirage Manufacturing from 1975 to 1983, this compact 20-footer represents an interesting chapter in American small boat design. With 550 hulls built over its eight-year production run, the Mirage 55 found a solid niche among sailors seeking an affordable entry into keelboat sailing. The boat's defining feature is its swing keel configuration, which allows the 5.33-foot draft to be reduced significantly for trailering and shallow water exploration. This versatility makes it particularly well-suited for coastal cruising, lake sailing, and weekend adventures where launching ramp access is important. The masthead sloop rig with 190 square feet of sail area provides adequate power for its 1,200-pound displacement, while the 320 pounds of ballast offer reasonable stability for a boat of this size. With a comfort ratio of 6.41, this design leans toward the sportier side of the spectrum rather than heavy cruising comfort. The fiberglass construction typical of its era has generally proven durable, though potential buyers should carefully inspect older hulls for osmotic blistering and structural integrity. The Mirage 55 serves best as a day sailor or short-term coastal cruiser for small crews seeking an affordable, trailerable keelboat experience.

About this estimate
  • Prices are based on recent asking prices from public listings — not actual sale prices, which are typically lower.
  • Condition is not factored in. A well-maintained boat with new sails and engine can be worth significantly more than a project boat of the same model.
  • Location affects price. Boats in landlocked states or areas with fewer buyers often sell for less than those on the coast.
  • Year of manufacture is not filtered. Older examples of this model will generally be priced lower than newer ones.
  • Included equipment varies widely. A boat with a full suite of electronics, dodger, and new standing rigging may command a large premium.
  • Outliers are automatically excluded using statistical filtering to improve accuracy, but some bad data may remain.

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
26.97
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
26.67
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
102.93
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
6.41
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
3.01
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. 5.58 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
5.68
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. 495.38 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. 26.85
