Thanks Randy for a great site!
The posted Date of Manuf of 1972 is incorrect on the Advance Demon spec page.
The Demon, being the donor boat to building the Sweet16, could not have started production 10yrs later than the Sweet 16.
In 1962, Advance Sailboat Corp was a manufacturer of many classes of one-design dinghys; including the Flying Dutchman, Flying Junior, US-1, Windmill, and the Demon 15.

Mr. Kuppersmith recognized a void in the market line and directed Charlie Teeter, Advance's designer and toolmaker, to develop a dinghy that was both stable, roomy enough for family and friends, lightweight, and easy to rig and trailer, yet quick and agile enough to be raced competitively as a one-design.

The Demon, a successful part of the Advance line, had been an extension of the Flying Junior. In its design, Mr. Teeter had added two feet to the FJ stern and retooled the top deck. Mr. Teeter was well aware of the characteristics of the high performance Flying Dutchman monohedral planing hull which the designer, Uffa van Essen, had carried over to the Flying Junior. The FJ was extended to the Demon from whence Mr. Teeter started the Sweet Sixteen development process.

A Demon hull was split medially from bow to stern. One of the half hulls was then place don a jig. The midline of the hull was faired medially with filler materially to form a new keel line. Through fiberglass and plastic surgery, the five feet three inches Demon beam was widened to six feet. Filler material was then sculpted forward n the flare of the hull to form the new bow, resulting in an overall length of sixteen feet, or nine inches longer than the Demon. The freeboard and shear were raised to accomplish symmetry, and a new top deck was designed for comfort and style. The resulting effort was the Sweet Sixteen.

Taken with grace from the Sweet 16 history website

So I must be at least 10 years off. Date correction and notes added.
