We just purchased a 2002 34 Catalina which came with the Maxwell 800 windlass but no anchor rode.
Congratulations! and Welcome. My manuals are on Shamrock. I'll check tomorrow. The manual posted here is for the 500 don't know if it's the same. I would go with what Maxwell recommends, they may have the manual on their website. Do you have, like Shamrock, the drum/gypsie? I very much like mine. Use the drum for a lot of heavy lifting.
FWIW Shamrock has 50 feet of chain and 150 feet of 3 strand nylon.

Just thought of something. Do you have up and down switches? I know some Catalinas were made with only up. You may consider adding the down switch if you don't already have it.
