Has anyone installed the ZARCOR stern perch seats on a Catalina 25? We chartered a larger Catalina this summer and my girls loved sitting on the stern seats. I am hoping putting them on the 25 will make the sail with "dear old dad" more. I am curious about how difficult the installation is and how useable the seats are on a smaller boat. I am worried that sitting there on the smaller bat will not be practical/fun. Any help will be appreciated.
