Lived aboard an Irwin 42 ketch (the center-cockpit without the raised aft-deck) off and on for about eight years in the 1980s-90s.
Hull was generally bullet-proof and seemingly unaffected by the
blisters of the era… Too much “window” space (to my eye) for any high-latitude endeavors, but clearly many Irwin 42s sailed the same waters as the OI 41’s and did well for recreational sailing -- but no sea-berths… was a sweet-handling boat for nearly 15-tons… the major fly in the ointment was that most of the
appliances and the
electrical systems were essentially trailer-house quality and the way it was built, upgrades often required something beyond minor surgery. Did I like it, yep… nice boat if you liked to putter (not a huge issue for for under-45 live-aboards), and on a beam reach she’d hunker down and really move. Oh, handling under power was about the easiest of any single-screw boat I can recall… Irwin overall – three stars, long-range sailing quality – fours-stars,
fiberglass – four stars, electrical/Galley – no stars, esthetics – I sure liked it at the time…
