S2 9.1

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 15 hp (11 kW) for docking and maneuvering. The fuel tank holds 15 U.S. gallons (57 L; 12 imp gal) and the fresh water tank has a capacity of 15 U.S. gallons (57 L; 12 imp gal).^[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 1.3 ft (0.4 m) taller, along with sails with more area were used on later boats and became the standard for the class.^[13]

Variants

The design has a hull speed of 6.7 kn (12.4 km/h).^[4][9]

Operational history

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]
