The Irwin 30 Citation is an American sailboat that was designed by Ted Irwin as a cruiser and first built in 1977.[1][2][3]
Production
The design was built by Irwin Yachts in the United States starting in 1977, but it is now out of production.[1][3][4]
Design
The Irwin 30 Citation is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, a raked stem, a plumb transom, a skeg-mounted rudder controlled by a wheel and a fixed shoal draft, optional deep fin keel or keel and centerboard. It displaces 10,400 lb (4,717 kg) and carries 4,300 lb (1,950 kg) of ballast.[1][3]
The deep fin keel-equipped version of the boat has a draft of 5.30 ft (1.62 m), while the centerboard-equipped version has a draft of 8.08 ft (2.46 m) with the centerboard extended and 4.0 ft (1.2 m) with it retracted, allowing operation in shallow water.[1][3]
The design was factory-fitted with a Japanese Yanmar diesel engine of 15 hp (11 kW) for docking and maneuvering. The fuel tank holds 30 U.S. gallons (110 L; 25 imp gal) and the fresh water tank has a capacity of 75 U.S. gallons (280 L; 62 imp gal).[1]
For sailing downwind the design may be equipped with a symmetrical spinnaker.[1][3]
The design has a hull speed of 6.95 kn (12.87 km/h).[3]
Operational history
The boat is supported by an active class club, Irwin Yacht Owners.[5]
