S2 7.9
sailboat class
The S2 7.9, originally called the Grand Slam 7.9, is a recreational keelboat that was designed by Graham & Schlageter as a one-design and Midget Ocean Racing Club (MORC) racer-cruiser and first built by S2 Yachts in Holland, Michigan, United States. The designation indicates the length overall in meters.
Production
In 1989 the company was asked by the S2 7.9 Class Association if the design could be put back into limited production and the company agreed, but with a minimum order of ten boats for production to be restarted. The association and the S2 dealership network tried to come up with the ten orders, but was unable to do so at that time. Practical Sailor magazine termed this incident, "an unfortunate commentary on the sailboat industry" and noted it marked the end of sailboat production for the company.
A few more boats were built by S2's Tiara division in 1990 and 1994.
Design
The S2 7.9 is built predominantly of hand laid fiberglass with an end-grain balsa core, with wood trim. All models have a raked stem, a plumb transom and a transom-hung, pivoting rudder controlled by a tiller.
The boat is normally fitted with a small outboard motor for docking and maneuvering. A German BMW inboard diesel engine of 7.5 hp (6 kW) was a factory option plus a few were factory-equipped with Yanmar diesels.

Why this record matters

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 1, 2026. The linked authority identifier is Q109973479. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1989, 1990 and 1994.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
