About the Oday 25

Built during O'Day's heyday in the 1970s, this compact cruiser emerged from a era when the Massachusetts builder was establishing itself as a dominant force in production sailboats. The Oday 25 represents the company's approach to creating affordable, well-built boats for the growing recreational sailing market. With its moderate proportions and traditional styling, this boat appeals to sailors seeking a manageable platform for coastal cruising and day sailing. The design emphasizes ease of handling over pure performance, making it particularly suitable for couples or small families venturing into protected waters and near-shore environments. O'Day's reputation for solid fiberglass construction and practical layouts shines through in this model. The boat features the clean, purposeful lines typical of 1970s design philosophy, avoiding unnecessary complexity while providing essential sailing functionality. Its size makes it an excellent choice for sailors transitioning from smaller boats or those seeking a low-maintenance weekend cruiser. The Oday 25 fits comfortably into the coastal cruising category, offering enough accommodation for short-term cruising while remaining simple enough for single-handed operation. Its enduring presence in the used boat market speaks to the model's fundamental soundness and continued appeal among recreational sailors.

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
239
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
17.17
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
17.52
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
2.02
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. 6.14
S# (Speed Number) The Speed Number (S#) is a quick performance index. Higher values indicate a faster, more powerful design relative to its size.
