I had a 1986 Cal 28, she was a fantastic boat, fast well built. The 1989 Irwin I just sold was 38 feet. I am now looking at a 1969 Irwin 32, want a smaller boat as not to have so much money invested. Both are well built, great boats. I don't think you would go wrong with which ever one you get.
Good luck, Capt.Terry
