Columbia and Iona relationship?

[Patricksalt]

I recently acquired a sailboat which was supposed to have been a T-23 Columbia. While trying to order replacement windows I realized that something was different about my boat from a typical T-23. The cabin top is different as well as the transom mine has an added feature concerning the rudder mount. Upon further inspection of the vessels interior I I noticed on the electric panel the name Iona 23. I googled Iona 23 and found a boat that looked very similar to mine. I was only able to find two pictures of an Iona 23 on the Internet both were similar but neither looked exactly like mine. In my opinion, my boat has Columbia windows just not the same as the T 23. The cabin top is definitely an Iona 23. I am very confused as in my cockpit there is a plaque that states that it is a Columbia design by Sparkman and Stevens of New York. The title and electric panel say Glen-coe boats as the builder. Other than the differences I described above this boat appears to look exactly the same as the Columbia 23, This goes for the interior as well. Does anyone have a clue about the origin of this vessel? I am getting the feeling that she may be a rare item. Any information or help would be greatly appreciated thank you.

Evidently, the Columbia 23 was designed by Alan Paine.

Aloha and welcome aboard!
The wonderful world of boating will reveal that sometimes things are not what they seem.
Congratulations on your new to you boat and I hope you have many enjoyable hours and days on the water with her.
I put a lot of time in on a Catalina 22 before I moved up to something larger. I sometimes long for the days of easy maintenance and ease of getting underway that the smaller boat offered.
kind regards,
