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]}

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]
