Derived from the DEMON, also built by Advance Sailboat Corp., which, in turn was an extended version of the FLYING JUNIOR. This from the SWEET SIXTEEN web site:
"A Demon hull was split medially from bow to stern. One of the half hulls was then placed on a jig. The center midline of the hull was re-faired to form a new keel line. The beam was increased to six feet. The flare of the hull was extended to form the new bow, resulting in an overall length of sixteen feet, or nine inches longer than the Demon. The freeboard and sheer were also raised and a new deck was designed...."
Charles Teeter was in-house designer and tool maker for Advance Sailboats Co.
