O'Day sold the molds to Rebel Industries in 1980 and that company built the design as the Spindrift One, with a modified cabin, with 76 boats completed.

It has a fractional sloop rig, a rounded raked stem, a vertical transom, a transom-hung rudder controlled by a tiller and a fixed fin keel or optional centerboard.

[1][2][4] The boat is normally fitted with a small 3 to 6 hp (2 to 4 kW) outboard motor for docking and maneuvering.

[5][9][10] In a 1994 review Richard Sherwood describes the design as "a very typical day sailer" and notes, "there is sharp bow entry and high freeboard; like the Rhodes 19, the Mariner can handle heavy weather.

We'd ask around before buying to determine if the newest Mariners can be raced as a one-design class against the older O’Day boats, if that’s what you have in mind.
