The boat was intended as a first cruising sailboat for an owner stepping up from a daysailer. The design put an emphasis on spaciousness and simplicity. The O'Day 20 is a recreational keelboat, built predominantly of fiberglass, with wood trim.

The design has a PHRF racing average handicap of 218 and a hull speed of . Operational history
In a 2010 review Steve Henkel wrote, "The O'Day 22 ... was introduced in 1972 and a year later the O'Day 20 came along. According to the yachting press of the time, the smaller O'Day 20 was a lower-priced follow-up to the similar O'Day 22. ... Best features: It is interesting to compare the O'Day 20 with her near sisterships, the O'Day 19 and 192, one longer and one shorter in LOD. For example, both these comps have more internal space than the O’Day 20. But the O'Day 20 has a slightly better Motion Index resulting from her extra 200 pounds of ballast, and slightly more speed due to her longer LWL. Worst features: Other than the above, we don't see much difference. Maybe the only really bad feature was in the higher new price..."

In a 1974 review in MotorBoating described the design as having, "four full-sized bunks, head, galley sink,
icebox and optional stove make her self-sufficient away from port. A tall rig and 3'11" draft (with centerboard down) make her a lively performer under sail. Four hundred pounds of lead ballast make her safely self-righting. And her shallow draft keel (14" centerboard up) and tabernacle stepped mast make her easy to trailer." See also
