Main halyard is 5/16", I found one on ebay 70' long and that seems to be about right as mine runs back to the cockpit thru a rope clutch, maybe a little long. I used a large needle and some heavy thread to sew the ends together then wrapped the connection with the thread and some tape, worked very well and ran smooth.
Thanks, Steve and Steve A. The manual calls for 70' of 3/8 dacron.
I've never quite figured out the correct mounting of the boom vang. The dealer installed the vang with the connected cleat to the boom and not the mast. I always found this to be odd based on owning other boats but who am I to doubt the wis-dumb of a dyed in the wool Catalina dealer? The manual shows the cleat connected to the mast. Out of the five 250's on the lake, there's one other with the vang mounted cleat onto the boom.
I should note that unlike other 250's there are no provisions installed on the deck to run the line from the vang to the cockpit.
I prefer having the vang's fiddle block with cleat on the boom rather than at the base of the mast. The line then dangles down resting on the companionway hatch - easy to reach. Others like to run the vang line back to the cockpit along with their halyards, cunningham, topping lift, etc.
Good luck with it, Bob, my manual shows 5/16" for the halyards and 3/8" for the mainsheet. I used 7/16" for the mainsheet, jibsheet and vang, diameter not critical, just easier to handle than the 3/8", for me anyway. PO used 1/2" for jibsheets, I prefer 7/16".
Safest way to make the exchange: Butt ends of old and new line together. Sew them together with some sailing twine. Make a light wrap of electrical tape around the joint to make it stiffer then haul away. If you just tape the ends together you run the risk of it coming apart as it goes through the block aloft.
Finding dacon line or rope of any size is a problem. West Marine: Zero. As were several other marine supply outlets. Even Googling 3/8 dacon rope brought nothing.

I see many places advertising polyester rope. I suspect that in this application they are the same, but I am not sure. The way the fiber spinning process is done can affect the elongation of the polymer chains, and thus affect stretch and tensile strength. But it is possible that these do not matter unless you're planning on racing.
It's possible that Google came up empty because you misspelled Dacron.

I can spell dacron but I do not always proof read. Dacron is what's recommended by Catalina. <hr height="1" noshade id="quote"></font id="quote"></blockquote id="quote"> It may be more difficult to find Dacron these days. The Dacron trademark is owned by Koch Industries, and it is illegal to use the trademark unless the fiber is spun or licenced by Invista. In the drive to reduce costs, and since the underlying patents for the technology are long since expired, I suspect that Dacron has been replaced by generic PET imported from Asia for most recreational marine applications. If someone sells you something that they call Dacron, it will be interesting to see if it is actually labeled that way.
It looks like WM has hundreds of products labeled as polyester, but none as Dacron.
I am speaking less as a sailor than as someone who has spent his entire career in the chemical industry.
