Design

It is acutter riggedsloop,with araked stemwith abowsprit,an angledtransom,an internally mounted spade-typeruddercontrolled by awheeland a fixed longkeel,with a cutaway forefoot and acenterboard.It displaces 7,000 lb (3,175 kg) and carries 2,000 lb (907 kg) of ballast.[1][4]
The boat has a draft of 6.67 ft (2.03 m) with the centerboard extended and 2.75 ft (0.84 m) with it retracted, allowing operation in shallow water, or ground transportation on atrailer.[1][4]
The boat is fitted with a JapaneseYanmardiesel engineof 8 hp (6 kW) or aUniversal Atomic 2gasoline enginefor docking and maneuvering. The fuel tank holds 20 U.S. gallons (76 L; 17 imp gal) and the fresh water tank has a capacity of 45 U.S. gallons (170 L; 37 imp gal).[1][4]
The design has sleeping accommodation for four people, with a double"V" -berthin the bow cabin and a U-shaped settee in the main cabin that can be combined with a drop-dinette table to become a second double berth. Thegalleyis located on the starboard side just forward of thecompanionwayladder. The galley is L-shaped and is equipped with a two-burner stove and a sink. The icebox is accessible from both the galley and the cockpit. The enclosedheadis located just aft of the bow cabin on the port side. Cabin headroom is 68 in (173 cm).[1][4]

Operational history
[edit]The boat is supported by an active class club, theIrwin Yacht Owners.[6]
In a 2010 review Steve Henkel wrote, "best features: Her layout below provides a feeling of spaciousness rare in a 25-footer. Her heavy displacement and wide beam makes her stable in a breeze. The icebox, on the port side, is accessible both from the cockpit (so those on deck don't have to bother the cook to get a cold drink) and also from below deck. Worst features: In light air she's slow. There was one of these in our home harbor, and I remember literally running rings around her in four or five knots with our (then)South Coast 23.Over 10 knots of breeze, she peps up. "[4]
