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
- S2 9.1 SM
- This original short mast-equipped model has a mast that is approximately 1.3 ft (0.4 m) shorter than the later standard mast. The boat has a length overall of 29.83 ft (9.1 m), a waterline length of 25.00 ft (7.6 m) and displaces 7,850 lb (3,561 kg). It has a draft of 5.50 ft (1.68 m) with the standard keel. The design has a hull speed of 6.7 kn (12.4 km/h).[4][9]
- S2 9.1
- This model has a length overall of 29.83 ft (9.1 m), a waterline length of 25.00 ft (7.6 m), displaces 7,850 lb (3,561 kg) and carries 3,200 lb (1,451 kg) of ballast. The boat has a draft of 5.50 ft (1.68 m) with the standard fin keel. The design has a hull speed of 6.7 kn (12.4 km/h).[1][6]
- S2 9.1 SD
- This shoal draft keel model has a length overall of 29.83 ft (9.1 m), a waterline length of 25.00 ft (7.6 m) and displaces 7,850 lb (3,561 kg). The boat has a draft of 4.50 ft (1.37 m) with the shoal draft keel. The design has a hull speed of 6.7 kn (12.4 km/h).[2][7]
- S2 9.1 SE
- This model has a length overall of 29.83 ft (9.1 m), a waterline length of 25.83 ft (7.9 m) and displaces 7,600 lb (3,447 kg). The boat has a draft of 5.40 ft (1.65 m) with the standard keel. The design has a hull speed of 6.81 kn (12.61 km/h).[3][8]
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]
