Irwin 25

The Irwin 25 is an American trailerable sailboat that was designed by Ted Irwin as a cruiser and first built in 1969.

Production
The design was built by Irwin Yachts in the United States from 1969 until 1976, but it is now out of production.

Design
The Irwin 25 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig; a spooned, raked stem; a raised counter, plumb transom; an internally mounted spade-type rudder controlled by a tiller and a fixed fin keel with a retractable centerboard. A fixed fin keel model was also available. It displaces 5400 lb and carries 2200 lb of lead ballast.

The keel-equipped version of the boat has a draft of 4.0 ft, while the centreboard-equipped version has a draft of 6.67 ft with the centerboard extended and 2.67 ft with it retracted, allowing operation in shallow water or ground transportation on a trailer.

The boat is normally fitted with a small 4 to 8 hp outboard motor, or an inboard motor for docking and maneuvering.

The design has sleeping accommodation for four to six people, with a double "V"-berth in the bow cabin, two straight settees in the main cabin, one of which can convert to a double with the drop-down dinette table, and an aft quarter berth on the port side. The galley is located on the starboard side abeam the companionway ladder. The galley is equipped with a fold-down two-burner stove, an icebox and a sink. The enclosed head is located just aft of the bow cabin on the port side. Cabin headroom is 69 in. The fresh water tank has a capacity of 14 u.s.gal

The design has a PHRF racing average handicap of 228 and a hull speed of 6.1 kn.

Operational history
The boat is supported by an active class club, the Irwin Yacht Owners.

In a 2010 review Steve Henkel wrote, "Ted Irwin grew up in St. Petersburg, FL, and as a kid sailed boats in Tampa Bay. As a young man, he worked briefly in the plant of Charlie Morgan's Morgan Yacht Corp. That experience may have rubbed off a bit on the design of his Irwin 25 (introduced in 1968), which to a great extent resembles the Morgan 24/25 ... introduced in 1965. Both boats were popular club racers in the later 1960s and 1970s, but somehow the Morgan usually had the edge. The Irwin has the same displacement but a bit more ballast, a foot shorter waterline but a longer LOD as her overhangs are not as chopped off as the Morgan's; she has many similarities below the waterline, including a high aspect ratio centerboard ... her headroom gains an inch due to her doghouse, and her PHRF is a scant three seconds per mile higher. She was available as a keel/centerboarder ... or with a full keel (4' 0" draft, 1825 lbs. ballast). She had a choice of layouts: settee berths and a portside quarter berth ... or a dinette arrangement. Best features: None notable. Worst features: Centerboards and pendants on these boats are prone to problems,"
