About the Oday 240

The O'Day 240 is a 24-foot trailerable daysailer and weekender designed by C.R. Hunt & Associates and built by O'Day Corporation in 1988 and 1989. Though production was brief — fewer than two years before O'Day's closure — the 240 represents the final expression of the company's commitment to accessible, family-oriented sailing. Its shallow wing keel keeps draft under three feet, making the boat easy to trail and launch at typical ramp facilities while still providing enough lateral resistance for confident upwind sailing. The cockpit is wide and self-bailing, suited to day sailing with a crew of three or four. Below, a simple cuddy cabin offers basic overnight accommodations — a V-berth forward and minimal galley — adequate for a weekend on the hook. The masthead sloop rig is straightforward and manageable for short-handed sailing. With a displacement under 3,600 lbs and a beam of 8'3", the 240 tows easily behind a mid-sized truck or SUV. The boat's relative scarcity on the used market is a direct result of its short production run, which can make finding good examples challenging but keeps values relatively stable.

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
 231
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
 16.96
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
 33.33
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
 177.82
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
 15.14
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
 2.15
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. 6.12
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. 687.39
