Irwin 65 Ketch
Description
The Irwin 65 Ketch (1981–1986, only 13 hulls built) was Ted Irwin’s ultimate statement: the largest production sailboat ever built in the United States at the time, and still one of the most voluminous center-cockpit ketches ever conceived. Designed as a luxurious, shoal-draft world cruiser for owners who wanted superyacht space on a (relatively) affordable budget, it stretches the classic Irwin formula to its absolute limit.
