The O'Day 25 is a small recreational [[Engineering:Keelboat|keelboat]], built predominantly of [[Chemistry:Fiberglass|fiberglass]], with wood trim. It has a masthead sloop rig, a transom-hung [[Engineering:Rudder|rudder]] and a fixed fin [[Engineering:Keel|keel]] or centerboard. It displaces {{convert|4007|lb|kg|0|abbr=on}} and carries {{convert|1825|lb|kg|0|abbr=on}} of ballast.<ref name="Data"/><ref name="Joy"/>

The boat has a draft of {{convert|4.50|ft|m|abbr=on}} with the standard keel, while the centerboard-equipped version  has a draft of {{convert|6.00|ft|m|abbr=on}} with the centerboard down and {{convert|2.25|ft|m|abbr=on}} with the centerboard up.<ref name="Data"/>

The boat is usually fitted with a small {{convert|4|to|8|hp|kW|0|abbr=on}} [[Engineering:Outboard motor|outboard motor]], but a {{convert|7|hp|kW|0|abbr=on}} [[Engineering:Universal Atomic 4|Universal Atomic 4]] and later a Japanese [[Company:Yanmar|Yanmar]] diesel engine were available factory options.<ref name="Data"/><ref name="Henkel"/>

The design has a PHRF racing average handicap of 234 and a [[Physics:Hull speed|hull speed]] of {{convert|6.14|kn|km/h|abbr=on}}.<ref name="Joy"/><ref name="Henkel"/>

==Operational history==
In a 2010 review Steve Henkel wrote, "the O'Day 25 ... came in two variations: the keel-centerboarder ... and a deep fin keel version with 4' 6" draft, 20 square feet more sail area, two-foot higher mast, and 50 pounds less ballast. Outboard power on a stern bracket (or a small Atomic 2 gasoline engine of 7&nbsp;hp) was the choice at one point; then diesels came in. Production of both types of O'Day 25s together totaled over 2,800 between 1975 and 1983, right at the peak of the Golden Age of sailboat sales in this size range. Best features: Here is a nice-looking, good (though not superb) quality boat, with plenty of owners with whom to fraternize if you like to socialize ... Worst features: The galley seems a bit skimpy to us ..."<ref name="Henkel"/>
