The S2 9.1 is an American sailboat that was designed by Graham & Schlageter as a Midget Ocean Racing Club (MORC) racer and first built in 1983. The boat was built in a variety of models. The designation indicates the approximate length overall in meters.[1] [2] [3] [4] [5] [6] [7] [8] [9] [10]
Production
The design was built by S2 Yachts in Holland, Michigan, United States from 1983 until 1987 with 127 boats completed, but it is now out of production.[1] [6] [11] [12]
Design
The S2 9.1 is a racing keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, a raked stem, a plumb transom, a transom-hung rudder controlled by a tiller and a fixed fin keel.[1] [6]
The boat is fitted with a Japanese Yanmar 2GM diesel engine of 150NaN0 for docking and maneuvering. The fuel tank holds and the fresh water tank has a capacity of .[1] [6]
The first seven boats built were delivered to customers with a shorter mast, now known as the "9.1 SM". Owners of those boats thought the design was under-powered and a mast about 1.31NaN1 taller, along with sails with more area were used on later boats and became the standard for the class.[13]

The boat is supported by an active class club that organizes racing events, the S2 9.1 Meter North American One Design Class Association.[14] [15]
In a 2002 review Bill Brockway reported in Sailing World, "one successful racer from Seattle says that his S2 9.1 tall-rig boat is a good all-rounder in medium air, best upwind at the upper end of a No. 1, and can sail well going deep on a downwind leg."[13]
