Character

Where this design lands on the numbers a shopper trusts — read straight from her own ratios.

Shoal draughtDraws 1.14 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.
LivelySea-kindly

Her heavy displacement on a narrow beam gives 34 — a sea-kindly motion in a seaway.

Comfort ratio 34

At 1.69 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.69

42% of her weight is ballast — stiff, standing up well to her sails.

What the fleet has seen

The Irwin Yachts 38-1, as the fleet has seen it

Derived from the videos the fleet has analysed of this model. ▶ marks open the moment aboard.

The Irwin Yachts 38-1 is a Masthead Sloop designed by Ted Irwin, built from 1970 to the present, with an LOA of 11.51 m and a displacement of 6985 kg. Its Keel/CB and spade rudder hull has a 3.20 m beam and a 2.92 m draft. Aboard *Lady K Sailing*, a review noted that Irwin sailboats from the 1980s often have poor construction, with deck hardware screwed directly into fiberglass or wooden toe rails, leading to water intrusion and soft decks.4:04 These boats have heavy, high-windage hulls that perform poorly under sail, often necessitating motor-sailing.7:11 Interior layouts frequently lack effective sea berths, adequate handholds, and ergonomic fiddles.6:38 While offering significant interior volume and center-cockpit configurations, they require extensive maintenance, including re-bedding hardware and fiberglass repair.8:04 Buyers should inspect for hull blistering and deck delamination with a moisture meter.8:54
