The boat was built in a variety of models. The designation indicates the approximate [length overall](/source/Length_overall) in meters.[1][2][3][4][5][6][7][8][9][10] ## Production The design was built by [S2 Yachts](/source/S2_Yachts) in [Holland, Michigan](/source/Holland,_Michigan), [United States](/source/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](/source/Keelboat), built predominantly of [fiberglass](/source/Fiberglass), with wood trim. It has a [masthead sloop](/source/Masthead_sloop) rig, a [raked stem](/source/Raked_stem), a plumb [transom](/source/Transom_(nautical)), a transom-hung [rudder](/source/Rudder) controlled by a [tiller](/source/Tiller) and a fixed fin [keel](/source/Keel).[1][6] The boat is fitted with a Japanese [Yanmar](/source/Yanmar) 2GM [diesel engine](/source/Diesel_engine) of 15 hp (11 kW) for docking and maneuvering. The fuel tank holds 15 US gallons (57 L) and the fresh water tank has a capacity of 15 US gallons (57 L).[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](/source/Length_overall) of 29.83 ft (9.1 m), a [waterline length](/source/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](/source/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] ## See also - [List of sailing boat types](/source/List_of_sailing_boat_types) ## References 1.
