Not a Columbia
I found a link to Challenger Yachts, (TN). I do know that your Challenger has no relation to Columbia Yachts.From "I" Boats.com" This Challenger Yachts (TN) sailboat has a hull made of fiberglass and has an overall length of 39.92 feet. The beam (or width) of this craft is 1210 inches. This sailboat is rigged as a Sloop. The sail area for the boat is 650 square feet. Approximate displacement for the vessel comes in at around 25200 pounds. According to our records, the draft of the boat is around 6'0". (Draft refers to the minimum amount of water needed to sail your vessel. This is an important number to remember.)"
