Manufacturer Provided Description

"The Irwin 52 is long on value and loaded with standard features. On deck there's a spacious walk-in cockpit, a roller furling headstay, thoughtfully-located hardware and much more. Below-deck systems have been analyzed and located for easy accessibility. The opulent main salon is airy and open, featuring two large comfortable L-shaped settees; a custom teak high-low dining table; a large liquor locker (with optional wetbar and ice maker); and a breakfast bar with an upholstered, swiveling captain's chair. The elaborate navigation station has ample chart and instrument space and another captain's chair. The galley is a gourmet's delight, with a tremendous amount of space for food preparation. Opposite the galley is a utility room with a pantry for additional food storage. The master stateroom has a full queen-sized berth, settee, and private head with a tub and shower stall. The forward guest stateroom also has a queen-sized centerline berth with a settee, and a private entrance to the day head with its tub and shower stall. The guest stateroom has upper and lower single berths. The tasteful use of richly varnished teak combined with coordinated mica colors provides a feeling of spacious elegance. A smooth 77-horsepower diesel auxiliary will push the Irwin 52 along quietly when desired. Generous water and fuel capacity means long trips are possible without frequent stopping."
