A number of you have been in contact with me about how to tune a Catalina 320 and what sails
work and don't work on it. Since I'm probably the only sailmaker in the country who has actually
spent enough time on these boats to develop some comprehensive numbers for the boat I thought
I would put together a tuning guide for you. What follows is the result of quite a bit of on-the-
water experience on the 320, both racing and day-sailing over a long period of time. I have a
number of customers racing these boats successfully now.
