One of the boats we are seriously considering for our first purchase is a 1992 Catalina tall rig with a wing keel. The owner has been meticulous in the boat's maintenance. It's never been in saltwater, but stayed in northern Lake Michigan. Woodwork is in great shape and the boat is very clean. However, the sails are still the original, making them 21 years old and will probably need to be replaced sometime soon. It has a furled 140% genoa and a mailsail with lazyjacks and a sail stack system. Any ballpark numbers of what we can expect to pay to have the sails replaced? Thanks!
