I have a 76 Irwin 37CC, I've had it for about three years and I haven't had the luck to take it out into the big blue, but I've been out on the Chesapeake by the Rappahanic River and my wife & I love her. She's got a full keel and is a ketch rig. The one major problem I've had is when there are light wind's, she doesn't want to go to windward at all, in fact after a couple of hours of trying to tack back & forth I found to my amazement that I had lost ground. We really like the boat overall though. Look at our pictures on the Irwin owners web site. Under mike & Glinda.
