Welcome to the SBO Forum. You likely have a million questions. You are correct trying to understand the language of "Boat". If for no other reason than to enable the crew here too understand your query.
Pictures of your problem will help break down the language barrier.
Catalina has done a great job of providing manuals. You might find what you seek here:

You can also ask the SBO shop resident
@Dave Groshong for his ideas.
As Don has indicated, Harken is one of the solid manufactures of block & tackle systems. I like and use their hardware on m boat.
Catalina built your boat's hull and deck. They outsourced the hardware (i.e. block & tackle etc.) that makes their hull move through the water.
If I was trying to solve your problem, I would first identify the needed systems. Then I would look at different product manufactures of those systems comparing quality and cost. Finally I would source the needed items from the store that has the items price and service that serves my need.
But that is just me. Your boat and your choice. It is what makes boat ownership so wonderful.
