Columbia information
Also have been looking at a demasted 23T, but unless we stumble across a used "close enough" rig from another boat, it looks like a new rig would exceed the value of the boat. Info on all Columbia models can be found at www.columbia-yachts.com; click on "model information" on the left and scroll down to 23T. There's a link on the page to Justin Thompson, who can provide copies of many of the original factory drawings and manuals.Good luck finding the rig!
