Keep setup and tear down stuff simple
Using your boat as a trailersailor I would not recommend all the go fast equipment or extra sail handling stuff. From your bio I see you’re making the boat convenient and comfortable for when you’re on the boat, which is the way to go. The standard factory sail adjusting equipment will handle any kind of wind or seas thrown at a Cat 25 if you learn how to use it.
Adding all the trick stuff has it’s purpose but, is additional setup and teardown time and when it has a malfunction your sailing trip is ruined.
The Catalina adjustable backstay, being attached at the stern and not disconnected when raising or lowering the mast may not add much time during setup normally but, when it gets tangled with something then sailing time is compromised because of time spent in the parking lot.
I would get rid of that furler, while it’s the cats meow when the weather changes, the time wasted on a trailer boat adds up and if it breaks during setup then the whole sailing trip is gone. Lazy jacks is another item on a trailer boat that takes more time during setup than having to wrestle with the sail occasionally.
Keep the rigging and sail plan simple, put all your effort into making the boat comfortable when not under sail!
