Dan, On our boat, a 1987 sail number 5680, the head windows are 10 inches by 4 and 1/4 opening. I would guess from that that the cut out is about 5 1/2 x 11 1/2. The catalog lists a Lewmar O window that fits a cut out about that size. Dave
Catalina used a lot of different sized port windows. My 79 is closer to 7 x 14. About the only way to tell is to measure the opening of your particular boat. Even better if you can take out the window and get a more precise measurement.
