Yeah. I guess I can see that. I am just used to boats that worse manuals.Well, I have sail number 310. The macerator plumbing and seacock location, as shown in the manual, is incorrect. In addition, a Y valve shown in the manual was eliminated with the arrangement in my boat. Some of the wiring is not where it is depicted in the manual. Clearly, changes were made in production and the manual was not updated.
I have some experience with technical manuals. I believe with a minimum of effort, Catalina could have done much better.
