Design

Rush 31

The Rush 31 is a racing keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, a raked stem, a reverse transom, an internally mounted spade-type rudder controlled by a tiller and a fixed fin keel. It displaces 6,620 lb (3,003 kg) and carries 2,755 lb (1,250 kg) of iron or lead ballast.^[1][2]

The boat has a draft of 4.58 ft (1.40 m) with the standard keel.^[1][2]

The boat is fitted with a French Renault Couach diesel engine for docking and maneuvering. The fuel tank holds 7 U.S. gallons (26 L; 5.8 imp gal) and the fresh water tank has a capacity of 24 U.S. gallons (91 L; 20 imp gal).^[1][2]

The design has sleeping accommodation for three people, with a single "V"-berth in the bow cabin and two straight settee berths in the main cabin. The galley is located on the port side at the companionway ladder. The galley is L-shaped and is equipped with a two-burner stove, an ice box and a sink. A navigation station is opposite the galley, on the starboard side. The head is located just aft of the bow cabin on both sides.^[1][2]

The design has a hull speed of 6.76 kn (12.52 km/h).^[2]

Operational history

The boat is supported by an active class club that organizes racing events, the Half Ton Class.^[9][10]

In its Rush Royal Standard model it was chosen as the one-design boat for the Tour de France à la voile for 1982-1983.^[11][12]
