The Irwin 23 is an American trailerable sailboat that was designed by Ted Irwin as a cruiser and first built in 1968.[1][2][3]
Production
[edit]The design was built by Irwin Yachts in the United States, from 1968 until 1975, but it is now out of production.[1][3][4]
Design
[edit]The Irwin 23 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, a spooned raked stem, a plumb transom, an internally mounted spade-type rudder controlled by a tiller and a fixed fin keel, with retractable centerboard. It displaces 3,200 lb (1,451 kg) and carries 1,500 lb (680 kg) of lead ballast.[1][3]
The boat has a draft of 5.75 ft (1.75 m) with the centerboard extended and 2.42 ft (0.74 m) with it retracted, allowing operation in shallow water or ground transportation on a trailer.[1][3]
The boat is normally fitted with a small 3 to 6 hp (2 to 4 kW) outboard motor for docking and maneuvering.[1][3]
The design has sleeping accommodation for four people, with a double "V"-berth in the bow cabin, a drop-down dinette table and a straight settee in the main cabin and an aft pilot berth on the port side. The galley is located on the port side amidships. The galley is equipped with a sink. The head is located in the bow cabin on the starboard side. Cabin headroom is 57 in (145 cm).[1][3]
For sailing downwind the design may be equipped with a symmetrical spinnaker.[1][3]
The design has a PHRF racing average handicap of 252 and a hull speed of 5.8 kn (10.7 km/h).[3]
Operational history
[edit]The boat is supported by an active class club, the Irwin Yacht Owners.[5]
In a 2010 review Steve Henkel wrote, "The Irwin 23 was the smallest boat commercially produced by Irwin, who ended up building hundreds of boats and dozens of models. Best features: Among her comp[etitor]s, the Irwin is probably the fastest boat, despite her PHRF rating and maximum theoretical speed being equal to both the Sovereign [23 and Sovereign Antares], which have no centerboard for going upwind efficiently, as does the Irwin. The Sovereigns also have higher topsides and a taller cabin, which may provide better headroom but contribute 'top hamper' or windage that tends to slow the boat upwind. Worst features: Irwin's construction quality tended to be so-so at best."[3]
