About the Oday 28

Originally built during O'Day's heyday in the 1970s and early 1980s, this 28-footer represents the Massachusetts builder's commitment to creating affordable, well-rounded sailboats for the growing recreational sailing market. O'Day earned a solid reputation for producing boats that balanced performance with practicality, and the 28 continues this tradition. Designed primarily for coastal cruising and daysailing, this boat offers a comfortable cockpit and sensible deck layout that makes it accessible to sailors of varying experience levels. The moderate displacement hull provides a good compromise between speed and stability, making it suitable for weekend adventures and extended coastal passages alike. Like many O'Day designs of this era, the 28 features a roomy interior relative to its length, with clever space utilization that accommodates overnight cruising for small crews. The boat's fiberglass construction reflects the quality standards O'Day maintained during its most successful period. While not particularly fast by modern standards, the O'Day 28 delivers predictable handling characteristics and forgiving sailing manners that have made it popular among families and sailing schools. Its reputation for durability has helped many examples remain actively sailed decades after production ended.

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
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
203
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
15.78
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
20.73
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
2.12
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. 6.42
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
