The Sidewinder was  MFG Boats' most popular sailboat. Well over 2000 were manufactured. I've seen them as early as 1973 and as late as 1979, but perhaps the range is even greater.

The boat was designed by the world famous designers Rod MacAlpine Downie and Dick Gibbs and was sold in two main configurations: cat and sloop. The hull had two slots for the centerboard, one for the cat rig and the other for the sloop. The boat was offered with a single or a two piece mast. The design of the hull was clearly for intended for speed.

There were up to 17 fleets active around the country in the 1970s, and the National Regattas were always well attended. The boat was fast, especially with the optional spinnaker, and a lot of fun to sail.
