I have a 2320 Parker.
For the bow, I have 2 - 7' sections of 1/4" galvanized chain. I may put in an additional length of chain.
If/when I use a stern line, it's usually a wreck anchor so I use only 1 - 7' length of 1/4" galvanized chain.
All connections are galvanized shackles.

If you look on the West Marine Website, you'll find a very informative article on "Selecting an Anchor Rode".
