Hi All,I apologize in advance for my ignorance in the subject. I recently purchased a 1974 Catalina 27 and I am looking foward to change the rigging.To be honest the boat was always in fresh waters and the rig does not show signs of abuse but I don't like to take chances so...The first question I have for you would be:1) How do I determine if I have a tall rig or not ? Would it help if I would provide you the following:I :34.50J :11.25P :28.66E :10.50These dimension were taken from my boat.From the archive info I tend to believe I have a standard RIG since the tall one is 36 if I am correct but I want to be 100% sure...2) Where would you buy it from ? I e-mailed to CatalinaDirect to know if they have it but afte 2 days no news.. I am in Canada Montreal.Thank you for your time
