The O'Day 25 is an American trailerable sailboat that was designed by C.R. Hunt & Associates.[1] [2] [3] [4]

Production

The boat was built by O'Day Corp. in the United States, with 2,898 completed between 1975 and 1984, when production ended. It was one of the company's most successful designs.[1]

Design

The O'Day 25 is a small recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, a transom-hung rudder and a fixed fin keel or centerboard. It displaces 40070NaN0 and carries 18250NaN0 of ballast.[1] [2]

The boat has a draft of 4.5feet with the standard keel, while the centerboard-equipped version has a draft of 6feet with the centerboard down and 2.25feet with the centerboard up.[1]

The boat is usually fitted with a small 4to outboard motor, but a 70NaN0 Universal Atomic 4 and later a Japanese Yanmar diesel engine were available factory options.[1] [4]

The design has a PHRF racing average handicap of 234 and a hull speed of 6.14kn.[2] [4]

Variants

  • Base model with a fixed fin keel with a draft of 4.5feet and standard height rig.[1] [2]
    O'Day 25 CB
  • Model with swing centerboard with a draft of 6feet. The majority of the production run was CB models.[1] [5]
    O'Day 25 CB TM
  • Model with swing centerboard with a draft of 6feet and a taller mast by about 2feet.[1] [6]

    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 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 ..."[4]
