Oh, it was an Irwin.

I think this is the racing version. It is a centerboard model. I think the cruiser has a fixed keel. I presently have the mast down because I'm replacing the step. Can't wait to sail it down to the Keys! I also was able to get ahold of Charley Morgan, who gave me some good information on the boat. It is a 1970 model, and in great shape!
