The design is a production follow-on to the 1959 Contest 25-1 and the 1974 Contest 25-2, both unrelated designs.[1][3]

Production

The design was built by Contest Yachts, a brand of Conyplex of the Netherlands. Production started in 1982 and ended in 1985, with about 30 boats completed, but it is now out of production. Production ended as a result of the early 1980s recession.[1][3][5]

Design

The Contest 25 OC is a recreational keelboat, built predominantly of fibreglass, with wood trim. It has a 7/8 fractional sloop rig with a deck-stepped mast with no spreaders, wire standing rigging and aluminum spars. The hull has a raked stem, a plumb transom, an internally mounted spade-type rudder controlled by a tiller and a fixed fin keel. It displaces 3,788 lb (1,718 kg) and carries 1,510 lb (685 kg) of cast iron ballast.[1][3][4][6]

The boat has a draft of 4.92 ft (1.50 m) with the standard keel.[1][3]

The boat is fitted with a Swedish Volvo Penta diesel engine of 7 hp (5 kW) for docking and manoeuvring. The fuel tank holds 20.4 U.S. gallons (77 L; 17.0 imp gal) and the fresh water tank has a capacity of 26 U.S. gallons (98 L; 22 imp gal).[1][3]

The design has sleeping accommodation for four people, with a double "V"-berth in the bow cabin and two straight settees in the main cabin. The galley is located on the port side just aft of the bow cabin. The galley is equipped with a two-burner stove and a sink. The head is located just aft of the bow cabin on both sides. Cabin headroom is 64 in (160 cm).[1][3][4]

For sailing downwind the design may be equipped with a spinnaker of 420 sq ft (39 m2). The boat has a PHRF racing average handicap of 264 and a hull speed of 6.2 kn (11.5 km/h).[3]

Operational history

In a 2010 review Steve Henkel wrote, "best features: The beam on the Contest is a foot wider than any of her comp[etitor]s. and her freeboard amidships is also relatively high ... Worst features: The Contest’s relatively deep draft (4'11") and fixed fin limit her cruising ground to deep-water territory, and her high PHRF must have been a disappointment to prospective buyers."[3]
